1350-1400: From the Middle English noun bobel which may have been from the Middle Dutch bubbel & bobbel and/or the Low German bubbel (bubble) and Middle Low German verb bubbele, all thought to be of echoic origin.  The related forms include the Swedish bubbla (bubble), the Danish boble (bubble) and the Dutch bobble.  The use to describe markets, inflated in value by speculation widely beyond any relationship to their intrinsic value, dates from the South Sea Bubble (a classic example of stock-price speculation) which began circa 1711 and collapsed in 1720.  In response to the collapse, the UK parliament passed The Bubble Act (1720), which required anyone seeking to float a joint-stock company to first secure a royal charter; interestingly, the act was supported by the South Sea Company before its failure.  Ever since cryptocurrencies emerged, analysts have been describing them as a bubble which will burst and while that has happened with hundreds of coins (the exchange collapses are something different), the industry thus far has continued with only with occasional periods of inflation and deflation; this makes cryptocurrencies highly volatile meaning there is much scope for profit and much risk of loss, the extent to which they're subject to insider trading an manipulation has been debated but only as a matter of degree.  Bubble & bubbling are nouns & verbs, bubbler is a noun, bubbled is a verb, bubbly is a noun & adjective, bubbleless & bubblelike are adjectives and bubblingly is an adverb; the noun plural is bubbles.

Tulips.  The collective noun police in the seventeenth century missed an opportunity in not declaring that henceforth the standard use would be: "a bubble of tulips".

However, although the South Sea affair was the first use of “bubble” to describe such a market condition, it wasn’t the first instance of a bubble, the most infamous of which was the Dutch tulpenmanie (tulip mania) which bounced during the 1630s, contract prices for some bulbs of the recently introduced and wildly fashionable flower reaching extraordinarily high levels, the values accelerating from 1634 until a sudden collapse in 1637.  Apparently just a thing explained by a classic supply and demand curve, the tulip bubble burst with the first big harvest which demonstrated the bulbs and flowers were really quite common and easy to grow.  In history, there would previously have been many bubbles but it wasn’t until the economies and financial systems of early-modern Europe were operating that the technical conditions existed for them to manifest in the form and to the extent we now understand.  Interestingly, for something often regarded as the proto-speculative asset bubble and a landmark in economic history, twentieth-century revisionist historians have suggested it was more a behavioral phenomenon than anything with any great influence on the operation of financial markets or the real economy, the “economic golden age” of the Dutch Republic apparently continuing (mostly) unaffected for almost a century after the bottom fell out of the tulip market.  The figurative uses have been created or emerged as required, the first reference pre-dating the tulip affair, the usual motion being andything lacking a desired firmness, substance, or permanence; the first recorded used was in the 1590s but it was likely long established in oral use.  The soap-bubble dates from 1800, bubble-shell is from 1847, bubble-gum was introduced in 1935 and bubble-bath appears first to have be sold in 1937.  The slang noun variation “bubbly” was first noted in 1920, an invention of US English to describe a happy, talkative young lady.

The term "bubble top" (also briefly as "bubble-top") came into use in the 1940s after advances in materials and manufacturing techniques allowed the cockpit canopies of aircraft to be made using large Perspex moldings.  The concept had been around for decades but it was the combination of modern plastics and the demands of wartime which made possible the mass-production of large moldings.  The designers called them "bubble canopies" but pilots preferred the snappier "bubbletop".  Spitfire TE288 was built in May 1945 at Vickers Armstrong's Castle Bromwich factory but, with the end of hostilities in Europe it was only briefly in service, mostly in a training role.  Gifted in 1964 to the Canterbury branch of the Brevet Club, it was mounted on a plinth as a memorial outside the club's building but by 1984 had become so valuable it was moved to the RNZAF (Royal New Zealand Air Force) museum at Wigram.  During restoration, molds were taken and a fibreglass replica was constructed to be placed on the plinth.  Optimized for the low-altitude performance needed to counter the threat of the German V1 “Doodlebugs” (an early cruise missile), the Spitfire Mk XVI was a variant of the Mark IX and powered by the Packard-built Rolls-Royce Merlin 266 engine rated 1,720 HP (horsepower).  Entering production in October 1944, 1,054 were built and as well as serving as interceptors, they were used in the ground attack role, notably against the sites from which the V2 missiles (an early ballistic missile and the first major step on the path to ICBMs (inter-continental ballistic missile) and the big rockets used by the US in the Apollo programme) were launched.  The bubble canopy afforded outstanding visibility while the clipped wingtips improved responsiveness (notably the superior roll-rate) while sacrificing some performance above 15,000 feet (4,500 metres) but by then the demands of aerial combat had shifted lower in the sky.

1961 Pontiac Ventura Sports Coupe (Bubble Top).

The term (as bubble top) later was applied to cars with rooflines in a shape which recalled the use in aviation although the structures were of conventional metal & glass.  The classic examples were the full-sized two-door hardtops produced by GM's (General Motors) Chevrolet and Pontiac divisions in 1960-1962, the 1961 models the most collectable.  The 1961 Pontiac Ventura Sports Coupe (a sub-model of the Catalina) pictured is fitted with Pontiac's much admired 8-Lug wheels, their exposed centres actually the brake drum to which the rim (in the true sense of the word) directly was bolted.  Introduced for 1960, the design was a fortuitous conjunction of fashion & function because as well as looking good, the heat dissipation qualities were outstanding, addressing one of the problems which plagued drum brakes.  Unfortunately, the design was not compatible with (outboard) disc brakes and as their fitment increased, sales of the option (circa US$125) fell and in 1968 production of the 8-Lug ceased.  

The word "bubble" spiked shortly after the start of the Covid-19 pandemic.  Over time, use has expanded to encompass large-scale operations like touring sporting teams and even the geographical spaces used for the 2022 Beijing Winter Olympics but the original meaning was more modest: small groups based on close friends, an extended family or co-workers.  These small bubbles weren't supposed to be too elastic and operated in conjunction with other limits imposed in various jurisdictions; a bubble might consist of a dozen people but a local authority might limit gatherings to ten in the one physical space so two could miss out, depending on the details in the local rules.  The way most governments handled the pandemic was a bit muddled but in such events, as in most wars, much is a muddle.  Bubble thus began as an an unofficial term used to describe the cluster of people beyond one's household with whom one felt comfortable in an age of what was believed a highly infectious virus.  Bubbles were however a means of risk-reduction, not a form of quarantine.  In a bubble, risk still exist, most obviously because some may belong to more than one bubble, contact thus having a multiplier effect, the greater the number of interactions, the greater the odds of infection so staying home and limiting physical contact with others remained preferable, the next best thing to an imposed quarantine.  The more rigorously administered bubbles used for events like the Olympics are essentially exercises in perimeter control, a defined "clean" area, entry into which is restricted to those tested and found uninfected.  At the scale of something like an Olympic games, it's a massive undertaking to secure the edges but, given sufficient resource allocation can be done although it's probably misleading to speak of such an operation as as a "bubble".  Done with the static-spaces of Olympic venues, they're really quarantine-zones.  Bubble more correctly describes touring sporting teams which move as isolated bubbles often through unregulated space.

The Bubble Skirt

A type of short skirt with a balloon style silhouette, the bubble dress (more accurately described as a bubble skirt because that’s the bit to which the description applies) is characterized by a voluminous skirt with the hem folded back on itself to create a “bubble” effect at the hemline.  Within the industry, it was initially called a tulip skirt, apparently because of an at least vague resemblance to the flower but the public preferred bubble.  It shouldn’t be confused with the modern tulip skirt and the tulip-bubble thing is just a linguistic coincidence; there’s no link with the Dutch tulipmania of the 1630s.  Stylistically, the bubble design is a borrowing from the nineteenth century bouffant gown which featured a silhouette made of a wide, full skirt resembling a hoop skirt, sometimes with a hoop or petticoat beneath to provide structural support.  While bouffant gowns could be tea (mid-calf) or floor length, bubble skirts tend to truncate the look well above the knee; while calf-length creations are seen in collects, they're rare on the high street.  Perhaps with a little more geometric accuracy, the design is known also as the “puffball” and, in an allusion to oriental imagery, the “harem” skirt.  Fashion designer Christian Lacroix (b 1951) became fond of the look and a variation included in his debut collection was dubbed le pouf but, in English, the idea of the “poof skirt” never caught on although it was used by furniture makers.

It must have been a memorable sight in the still austere post-war world, a sheath dress made voluminous with layers of organza or tulle, the result a cocoon-like dress with which Pierre Cardin (1922-2022) and Hubert de Givenchy (1927-2018) experimented in 1954 and 1958, respectively. A year later, Yves Saint Laurent (1936-2008) for Dior added the combination of a dropped waist dress and bubble skirt; post-modernism had arrived.  For dressmakers, bubble fashion presented a structural challenge and mass-production became economically feasible only because of advances in material engineering, newly available plastics able to be molded in a way that made possible the unique inner construction and iconic drape of the fabric.  For that effect to work, bubble skirts must be made with a soft, pliable fabric and the catwalk originals were constructed from silk, as are many of the high end articles available today but mass-market copies are usually rendered from cotton, polyester knits, satin or taffeta.

The bubble skirt was never a staple of the shows in the sense that it would be missing from annual or seasonal collections, sometimes for a decade or more and sales were never high, hardly surprising given it was not often a flattering look for women above a certain age (perhaps anyone aged over eight or nine).  Deconstructing the style hints at why: a hemline which loops around and comes back up (created sometimes by including a tighter bottom half with the bulk of additional material above), it formed a shape not dissimilar to a pillow midway through losing its stuffing.  For that reason, models caution the look works best when combined with a sleek, fitted top to emphasize the slimness of the waistline, cinched if necessary with a tie or belt of some sort to delineate when one thing starts and the other finishes.  The bubble needs to be the feature too, avoiding details or accessories which might otherwise distract; if one appears to be wearing a partially un-stuffed pillow, the point needs to be made it’s being done on purpose and the obvious way that's achieved is to ensure it's the focus piece.  Really, tempting though it may seem in the catalogue, it's a style for experts in a narrow BMI (body mass index) range.

On the catwalks however, again seemingly every decade or so, the bubble returns, the industry relying on the short attention span of consumers of pop culture inducing a collective amnesia which allows many resuscitations in tailoring to seem vaguely original or at least a novel variation on the theme.  Still, if ever a good case could be made for a take on a whimsical 1950s creation to re-appear, it was the staging of the first shows of the 2020-2021 post-pandemic world and the houses responded, Louis Vuitton, Erdem, Simone Rocha and JW Anderson all with billowy offerings; even seen was an improbably exuberant flourish of volume from Burberry.  What appeared on the post-Covid catwalk seemed less disciplined than the post-war originals, the precise constraints of intricately stitched tulle forsaken to encourage rather more swish and flow, the look romantic rather than decadent.  Generally the reception was polite but for those who hoped for a more adventurous interpretation, history suggests the bubble will be back in a dozen-odd years.

Strapless, pale-pink bubble gown (Look 53) from Balenciaga's Spring/Summer 2026 collection, Paris Fashion Week, October 2025.

By using a structural bubble hem, the gown illustrates how a light-weight fabric can be made to emulate a selective rigidity.  The fashion critics said the oversized glasses were there as an evocation of futurism but the skinnytokers (said to be “the acceptable pro ana”) call it the “bug-eye look” and recommend them because the exaggerated size of the frames and lens creates the visual illusion of making the face appear thinner.  Most catwalk models are of course anyway splendidly slender but skinnytok's skinnysplainers would suggest they’d look good even on them; in such matters, the skinnytokers are the world's foremost experts.  The double-faced fabric was neo gazar (the original gazar a silk organza with a plain weave created by the house in 1957-1958), co-developed by Balenciaga and the textile company Lorma, incorporating a soft silk & wool lamiset weft.  The advantages neo gazar offers are said to be a capacity to maintain a shape without the same extent of internal framework, while being easier to work with than original, more rigid, silk gazar.

Although Look 53 may be a classic case study of the disconnect between what appears on catwalks in headline collections and stuff actually sold, that’s not a criticism because such pieces must be assessed on the basis of fulfilling their intended purpose and that this creation admirably did.  Pierpaolo Piccioli’s (b 1967) first collection for the house (after a long stint at Valentino) was much anticipated by critics, most of whom appear to have been impressed, noting the designer’s mastery handling of the distinctive “house codes” Balenciaga has over the decades made signatures.  So everybody liked the clothes but whether the show notes were of much help is uncertain, notably the text: “The meaning of Balenciaga is a methodology.  The process of creation as ideology, as identity, an expression of humanity and human invention.”  The collection deserved to be judged on its merits but what to make of the show notes?  It was grammatically coherent English and so laden with words and phrases with recognizable semantic associations that, in a strictly linguistic sense, the passage couldn’t be devoid of meaning but what would be concluded by those not students of textual deconstruction?  It was of course a delight for those students because it was an exemplar of what in literary theory is called “semantic inflation” (or “floating signifiers”), abstract nouns arranged in a way that might be used by sentences saying something profound while yielding no precise meaning.  Structurally, what each phrase did was substitute a metaphorical association for a concrete predication; nothing could be proved or falsified.

Walmart Mission and Vision Statement: No background in literary deconstruction required.

Just about every process of course has a “method” with “methodology” used just as a “fancy” way of making what seems an obvious point and while the process of creation certainly can be an expression of an ideology, something more specific in the text may have helped.  After all, what people create is by definition “an expression of humanity and human invention”, that applying equally to bubble dresses, hamburgers and nuclear weapons.  Still, while not as succinct a statement as something like E=mc², the show notes were not useless because earnest students of marketing effortlessly would identify the ritualistic, atmospheric prose as part of the discourse of luxury branding which needs to convey characteristics such as “edginess”, “avant-garde sensibility”, “intellectual seriousness” and a certain distance from the vulgar business of selling cheap clothes to the working class shopping at places like Walmart.  Between themselves, in expressions, gestures, clothing and more, the rich often communicate in intricate or elaborate codes not obvious to others.  Positioning the company in the cultural & economic milieu of those used to abstractions, Balenciaga would be assured the folk who buy their garments could (unlike the literalists at price-tag-focused Walmart), interpret connotative meaning despite the absence of denotative precision, the trick being to read not what is said but what is meant.  Indeed, so impressed might some of them have been by the show notes they may even have “sampled” chunks of the text for their next mission statement because it’s hard to improve on: “Recollection rather than tribute, shadows of Balenciaga’s architectonic shapes are embedded in the actuality of today—bold and disruptive volumes applied to clothes that define our modern wardrobe.  A vocabulary of contemporaneity, entirely transformed through approach.”

Bubbletop

Bubbletop (pronounced buhb-uhl-top)

(1) In aircraft design, a design of pilot’s canopy (originally military slang for what designers dubbed the “bubble canopy”, a Perspex molding which afforded exceptional outward visibility).

(2) An automobile using a transparent structure over the passenger compartment, replacing the usual combination of roof & windows.

(3) A descriptor of certain automobiles (as "Bubble Top") of the early 1960s, based on the shape rather than the method of construction, conventional metal and glass used.

1940s: The construct was bubble +‎ top.  Bubble dates from the late fourteenth century and was from the Middle English noun bobel which may have been from the Middle Dutch bubbel & bobbel and/or the Low German bubbel (bubble) and Middle Low German verb bubbele, all thought to be of echoic origin.  The related forms include the Swedish bubbla (bubble), the Danish boble (bubble) and the Dutch bobble.  Top pre-dates 1000 and was from the Middle English top, toppe & tope (top, highest part; summit; crest; tassel, tuft; (spinning) top, ball; a tuft or ball at the highest point of anything), and the Old English top & toppa (top, summit, tuft of hair), from the Proto-West Germanic topp, from the Proto-Germanic tuppaz (braid, pigtail, end), of unknown origin.  It was cognate with the Old Norse toppr (top), the Scots tap (top), the North Frisian top, tap & tup (top), the Saterland Frisian Top (top), the West Frisian top (top), the Dutch top (top, summit, peak), the Low German Topp (top), the German Zopf (braid, pigtail, plait, top), the Swedish topp (top, peak, summit, tip) and the Icelandic toppur (top).  Alternative forms are common; bubble-top in automotive & aeronautical engineering and bubble top in fashion.  Bubbletop is a noun and bubbletopped is an adjective; the noun plural is bubbletops.

Evolution of the Mustang's bubbletop: P-51C (top), P-51 III (centre) and P-51D (bottom).

“Bubbletop” began as World War II (1939-1945) era military slang for officially was described as the “bubble canopy”, the transparent structure sitting atop the cockpit of fighter aircraft, the advantages being (1) superior visibility (the purest interpretation of the design affording an unobstructed, 360° field-of-view, (2) improved aerodynamics, (3) easier cockpit ingress & egress (of some significance to pilots force to parachute and (4), weight reduction (in some cases).  Bubbletops had been seen on drawing boards in the early days of aviation and some were built during World War I (1914-1918) but it was the advent of Perspex and the development of industrial techniques suitable for the creation of large, variably-curved moldings which made mass-production practical.  The best known early implementations were those added to existing air-frames including the Supermarine Spitfire, Republic P-47 Thunderbolt and North American P-51 Mustang.  By 1943, the concept had become the default choice for fighter aircraft and the technology was applied also to similar apparatuses used elsewhere on the fuselage where they were styled usually as “blisters”.  In the post war years it extended to other types, most dramatically in the Bell 47 helicopter where the cabin was almost spherical, some 70% of the structure clear Perspex.

The enormous and rapid advances in wartime aeronautics profoundly influenced designers in many fields and nowhere was that more obvious than in the cars which began to appear in the US during the 1950s.  Elements drawn variously from aeronautics and ballistics did appear in the first generation of genuinely new post-war models (most of what was offered between 1945-1948 being barely revised versions of the 1942 lines) but it was in the next decade the designers were able to embrace the jet-age (a phrase which before it referred to the mass-market jet-airline travel made possible by the Boeing 707 (which entered commercial service in 1958) was an allusion to military aircraft, machines which during the Cold War were a frequent sight in popular culture).  On motif the designers couldn’t resist was the bubble canopy, something which never caught on in mass-production although Perspex roofed cars were briefly offered before word of their unsuitability for use in direct sunlight became legion.

GM Firebird XP-21 (Firebird I, 1953).

Not content with borrowing the odd element from aircraft, the General Motors (GM) team decided the best way to test which concepts were adaptable from sky to road was to “put wheels on a jet aircraft” and although they didn’t do that literally, by 1953 when Firebird XP-21 was first displayed, it certainly looked as though it was exactly that.  Its other novelty was it was powered by a gas turbine engine, the first time a major manufacturer in the US had built such a thing although a number of inventors had produced their own one-offs.  When the XP-21 (re-named Firebird I for the show circuit) made its debut, some in the press referred to it as a “prototype” but GM never envisaged it as the basis for a production car, being impractical for any purpose other than component-testing; it should thus be thought of as a “test-bed”.  The bubble canopy looked as if it could have come from a US Air Force (UFAF) fighter jet and would have contributed to the aerodynamically efficiency, the 370 hp (280 kW), fibreglass-bodied Firebird I said to be capable of achieving 200 mph (320 km/h) although it’s believed this number came from slide-rule calculations and was never tested.  Despite that, in its day the Firebird II made quite a splash and a depiction of it sits atop the trophy (named after the car’s designer, Harley Earl (1893–1969), the long time head of GM’s styling studio) presented each year to the winner of NASCAR’s (National Association for Stock Car Auto Racing) premiere event, the Daytona 500.

GM Firebird II (1956).

Compared with its predecessor, the Firebird II (1956), rendered this time in titanium was almost restrained, the Perspex canopy a multi-part structure over a passenger compartment designed to seat “a family of four”.  The family might have chosen to drive mostly in darkness because the heat build-up under the midday sun would have tested the “individually-controlled air conditioning”, a system upon which comfort depended because the Perspex sections were fixed; there were no opening “windows”.  Still, even if hot, the family would have got places fast because the same 200 mph capability was claimed.

GM Firebird III (1958).

The Firebird III was displayed at the 1958 Motorama and although GM never built any car quite like it, within a season, elements of it did begin to appear on regular production models in showrooms (notably the rear skegs which Cadillac used for a couple of years) and some of its features are today standard equipment in even quite modest vehicles.  The striking “double bubbletop” never made the assembly lines although some race cars have at least partially implemented the concept.  What proved more of a harbinger was the specification, the Firebird III fitted with anti-lock brakes, cruise control, air conditioning, an automated “accident avoidance system” and instead of a steering wheel, the driver controlled the thing with a joystick, installed in a centrally-mounted “Unicontrol & Instrument Panel”.  All these were analogue-era electro-mechanical devices too bulky, fragile or expensive for mass production, wider adoption in the decades to come made possible by integrated circuits (IC) and micro-processors.

1959 Cadillac Cyclone (XP-74).

Borrowing from the Firebird II, Cadillac also used a bubble top for the Cyclone (XP-74) concept car which in 1959 toured the show circuit.  Although it was powered by the corporation’s standard 390 cubic inch (6.5 litre) V8, there was some adventurous engineering including a rear-mounted automatic transaxle and independent rear suspension (using swing axles, something not as bad as it sounds given the grip of tyres at the time) but few dwelt long on such things, their attention grabbed by features such as the bubble top (this time silver coated for UV (ultra violet) protection) which opened automatically in conjunction with the electrically operated sliding doors.  The Perspex bubble canopies from fighter aircraft never caught on for road or race cars but so aerodynamically efficient was the shape it found several niches.

1953 Ferrari F166MM Spider by Vignale (left) and 1969 MGCGT (centre) and the MGC's replica hood in  fibreglass (right).

Bubbles often appeared atop the hood (bonnet) to provide clearance for components inconveniently tall (typically induction systems).  Most were centrally located (there was the occasional symmetrical pair) but the when BMH (British Motor Holdings, the old  BMC (British Motor Corporation) shoehorned their big, heavy straight-six into the MGB (1963-1980), it wouldn’t fit under the bonnet, the problem not the cylinder head but the tall radiator so the usual solution of a “bonnet bulge” was used.  However, for that to clear the forward carburetor, the bulge would have been absurdly high so a small bubble (usually, ones this size are referred to as "blisters") was added.  It probably annoyed some there wasn’t a matching (fake) one on the other side but it’s part of the MGC’s charm, a quality which for years most found elusive although it’s now more appreciated.  For MGC owners wish to shed some weight or for MGB owners who like the look, the “bonnet with bubble” is now available in fibreglass.

The winning Ford GT40 Mark IV (J-Car) with bubble to the right, Le Mans 1967 (left) and the after-market (for replicas) “Gurney Bubble” (right).

US racing driver Dan Gurney (1931–2018) stood 6' 4" (1.9 m) tall which could be accommodated in most sports cars and certainly on Formula One but when he came to drive the Ford GT40 Mark IV it was found he simply didn’t fit when wearing his crash helmet.  The original GT40 (1964) gained its name from the height being 40 inches (1016 mm) but Mark IV (the “J-Car”, 1966) was lower still at 39.4 inches (1,000 mm).  Gurney was the tallest ever to drive the GT40 and the solution sounds brutish but fix was effected elegantly, a “bubble added to the roof to clear the helmet.  Gurney and AJ Foyt (b 1935) drove the GT40 to victory in the 1967 Le Mans 24-hour endurance classic and the protrusion clearly didn’t compromise straight-line speed, the pair clocked at 213 mph (343 km’h), on the famous 3.6-mile Mulsanne Straight (which was a uninterrupted 3.6 miles (5.8 km) until the Fédération Internationale de l'Automobile (the FIA; the International Automobile Federation and world sport’s dopiest regulatory body) imposed two “chicanes”),  Known ever since as the “Gurney Bubble”, such is the appeal that they’re now available for any GT40 replica: Like the AC Shelby Cobra, the GT40 “reproduction” industry is active and there are many times more of these than there are survivors of 105 originals.

Ferrari 250 GT “Tour de France” LWB Berlinettas by Zagato: The “double bubble” roof (left), the Hofmeister kink (centre) and the famous “Z” kink, (right).

The Italian coachbuilding house Zagato was founded in 1919 by Ugo Zagato (1890-1968) and since the early post-war years, their designs have sometimes been polarizing (the phrase “acquired taste” sometimes seen), their angularity often contrasted with the lines of other, notably Pinninfarina and Bertone but unlike many which have over the years folded, Zagato remains active still.  One Zagato design never criticized was his run in 1956 of five Ferrari 250 GT “Tour de France” LWB Berlinettas, memorable also for introducing the signature “Zagato double-bubble roof.  The roof was practical in that it better accommodated taller occupants but it really was a visual trick and a variation on the trick Mercedes-Benz used on the “Pagoda” (W113; 230, 250 & 280 SL; 1963-1971) which they explained by saying “We didn’t lower the roof, we rained the windows”.  The other famous feature (which appeared on only one) was the fetching “Z” shape on the rear pillar, replacing the “Hofmeister kink” used on some others.

1962 Chevrolet Impala “bubble top” Sport Coupe (left), 1963 Ford Consul Capri (centre) and 1972 BMW 3.0CS (E9, right).

The 1959 Chevrolet quickly came to be nicknamed “bubble top” and the style spread, both within GM and beyond.  The “bubble top” reference was to the canopy on aircraft like the P-51D Mustang but was an allusion to the shape, not the materials used; on cars things were done in traditional glass and metal.  Across the Atlantic, Ford in the UK applied the idea to their Consul Capri (1961-1964), a two-door hardtop which the company wanted to be thought of as a “co-respondent's” car (ie the sort of rakish design which would appeal to the sort of chap who slept with other men’s wives, later to be named as “co-respondent” in divorce proceedings).  The Capri was a marketplace failure and the styling was at the time much criticized but it’s now valued as a period piece.  Chevrolet abandoned the look on the full-size cars after 1963 but it was revived for the second series Corvair (1965-1969).  A fine implementation was achieved in the roofline of the BMW E9 (1968-1975) which remains the company’s finest hour.

The bubble shirt and bubble tops.

The bubble skirt (worn by Lindsay Lohan (centre)) is one of those garments which seems never to quite die, although there are many who wish it would.  Once (or for an unfortunate generation, twice) every fashion cycle (typically 10-12 years), the industry does one of its "pushes" and bubble skirts show up in the high street, encouraged sometimes by the odd catwalk appearance; it will happen again.  While the dreaded bubble skirt is easily identifiable, the “bubble top” is less defined but there seem to be two variations: (1) a top with a “bubble skirt-like” appendage gathering unhappily just above the hips (left) and (2) a kind of “boob tube” which, instead of being tightly fitted is topped with an additional layer of material, loosely gathered.  The advantages of the latter (which may be thought of as a “boob bubble”) are it can (1) without any additional devices create the illusion of a fuller bust and (2) allow a strapless bra to be worn, something visually difficult with most boob tubes because the underwear’s outline is obvious under the tight material.

Hikikomori

Hikikomori (pronounced hic-hee-kee-koh-moh-ree)

(1) A mode of behaviour in which an individual becomes a recluse from society, typically remaining isolated, sometimes for decades, in a single room at home.

(2) An individual exhibiting this behaviour for a sustained period.

1990s: From the Japanese noun 引きこもり or 引き籠もり (hikikomori), (literally “pulling inward; being confined”), from the verb hikikomoru (引きこもる).  The construct was 引く (hiku) (to pull, to draw back, to withdraw) + 籠る or こもる (komoru) (to shut oneself away; to remain secluded; to stay inside).  So, the literal translation is something like “to withdraw and remain shut in” but, used to mean “one who has withdrawn into seclusion”, the more common verbal shorthand is “shut in” (in the sense of “acute social withdrawal” or something in that vein).  Although once regarded as a uniquely Japanese phenomenon, it’s not now thought culturally specific, that perception a product of the condition and its extent first being widely documented in Japanese publications.  In Japan, the usual clipping is hikki.  Hikikomori is a noun; the noun plural is plural hikikomori or hikikomoris.

The element komoru is not recent; historically it referred not only to people but also generally to the concept of “being shut away or enclosed” or natural features such as a mountain at times when it was encircled by clouds or a land mass visible only at low tide (a tidal island or tombolo (a sand bar or path of dirt that connects this land to the coastline when the tide falls)).  More typically however it was use of individuals opting for whatever reason to “remain indoors” (such as those who, for religious reasons, might retreat to a mountain hermitage, either for a period of contemplation (that might last a lifetime) or to escape a society they had come to view as in some way “unsatisfactory”.  The concept of hikikomori is different in that those “afflicted” are not deemed to be motivated by a religious calling or philosophical position but instead “suffering” a visceral reaction to the condition of society or their life, manifesting as an urge to retreat from the outside world to a “safe” enclosed space.  This aligns with the modern use in psychiatry.

So use of the verb hikikomoru goes back generations but the noun hikikomori came into use only in the 1990s when the psychiatric sense was popularized in the book Shakaiteki Hikikomori: Owaranai Shishunki (Social Withdrawal: Adolescence Without End, 1998) by Japanese psychiatrist Dr Tamaki Saitō san (b 1961).  For reasons both structural and historic, it’s rare for concepts in psychiatry to have origins in Japan so hikikomori enjoys an unusual place in modern nosology (the characteristics or scientific understanding of a specific disease).  Internationally however, hikikomori “caught on” and became part of the standard jargon; that was not because there was any particular interest in categorizing uniquely Japanese phenomena but because clinicians in other places had for some time been aware the behaviour was not uncommon in their countries.  The Western media soon took an interest in hikikomoru because editors knew stories about “disaffected adolescents locking themselves in their bedrooms for years” would be good productive clickbait, readers likely to be attracted by tales of troubled geniuses or depressed emos.

The companion terms are the English language acronym NEET (Not in Employment, Education or Training) and the Japanese オタク (Otaku).  Otaku (best translated as “geek” or “nerd”, reflecting the bias in use towards computers or other tech) emerged from fandom community associated with Macross (a Japanese science fiction mecha anime media franchise), the use derived from お宅 (otaku) (you), from the honorific form 宅 (taku) (home), thus the notion of Macross being “your home” (ie one’s natural environment”).  From the Macross obsessives, use extended to “obsessive interest in something” (especially (and often exclusively) Japanese anime or manga).  While originally a derogatory term, fandom communities “reclaimed” otaku as a self-descriptor although it does continue to be applied disparagingly.  In the West, it tends to be neutral, used to refer to anyone with a strong interest (obsessive or not) in anime or manga.  NEET is applied not to all those “unemployed” but only those thought apathetic or who exhibit the characteristics of a hikikomori but in sub-groups, the play on words with the English “neat” (in the sense “excellent, desirable; interesting; cool”) prevails.

The hikikomori came to be known as “the lost generation” and that it was a thing identified in the 1990s and celebrated (in a sense, that can be the right word) in Dr Saitō san’s 1998 book is interesting because it was the 1990s that came to be known as “the lost decade”).  Although there were of course the inevitable fluctuations in the growth curve, over the 40 years between 1949-1989, the trend for the Japanese economy in most indicative measures (GDP (gross domestic product), GNP (gross national product), RPP (relative purchasing power), AMWE (average male weekly earning), corporate profits, exports, trade surplus etc) tended upwards and while, given the country’s paucity of natural resources, that was an achievement in some ways even more remarkable than the Wirtschaftswunder (“economic miracle”) witnessed in the FRG (Bundesrepublik Deutschland (Federal Republic of Germany; the old West Germany, 1949-1990) over the same period, the stellar performance was not without consequences and some of those consequences triggered reactions.  The strength of Japanese economy was by the 1980s producing notable distortions in the world’s production and trading systems and that of course affected currencies, as aspect of the international system distorted still further by this happening at a time when currencies weren’t allowed to “float” to the extent now familiar, governments and central banks (in some places, for this purpose, the distinction between the two institutions not significant) sometimes literally “setting the rate” by fiat.  All this required trips to Tokyo by the US Treasury Secretary to negotiate the devaluation of the US dollar and it was in the 1970s & 1980s the deindustrialization of the US economy really began, later forces such as automation, computing, the CCP (Chinese Communist Party) proving most adept at capitalism and AI (artificial intelligence) being building blocks in what continues to evolve as the “new model”.  US politicians of course responded to this by inducing Japan, the FRG and others running substantial trade surpluses with the US to shift some production to the US and that to some extent reduced the imbalances but, factories and assembly lines in the 1980s not being what they were a generation earlier, US employment levels or incomes certainly weren't restored.

The Japanese economy continued to flourish and the fear in the US was often expressed as “Japan taking over the world”.  That this might be done by the use of Japanese money was a thought bad enough but to add insult to injury, much of the money was in US dollars gained by Americans paying Japanese companies for the sort of stuff once manufactured in their now shuttered factories.  Against that threat, the world’s most potent military (a chunk of which was allocated to the defense of Japan) and an impressive arsenal of thermo-nuclear weapons able to be delivered anywhere on the planet was not a great deal of help.  What was a help was economic reality because by 1989 one part of the Japanese economy had developed into a disproportionately large bubble; at this bubble’s peak, the notional value of Tokyo real estate market was greater than the entire continental US.  Although obviously not something that could have been realized in the “real world” (ie had every piece of real estate in Tokyo been offered for sale at its nominal valuation), the numbers were indicative of one of economic history’s most notable imbalances.  In a kind of national hubris (an exuberance as “irrational” as anything seen since the Dutch “tulip bubble”), the combination of extreme over-confidence by speculators and ultra-loose credit policies by lenders had resulted in land values in Japanese cities (Tokyo the most extreme example) coming to be decoupled from economic reality (and, because of the “extrapolation effect” by which especially the value of commercial floor-space was calculated within markets), ultimately, basic mathematical reality too.

An (extreme) example of a similar disconnection from reality would be Donald Trump (b 1946; POTUS 2017-2021 and since 2025) applying the metrics and methods of valuation (that for decades have served him well) to news cosmologists had used their new “big telescopes” to discover a “perfect Earth-like” planet (one of the so-called exoplanets (any planet located outside of our solar system)) a “mere” hundred light-years distant.  Obviously, this planet (or at least what it was a century ago). with an ideal climate, ample resources, stable geology etc, would contain much desirable real estate so the valuations attached to this unspoiled paradise would’ in other circumstances, be high.  There might be some uncertainly if it couldn’t be determined if the place had inhabitants (on Earth such folk have proved troublesome in land-grabs) but that’s just something speculators have to “factor in”.  The problem however is that however desirable might be the exoplanet’s lands and seas, they’re a “stranded asset” because of the distance from Earth; we cannot contemplate travelling a single light-year, let alone a hundred.

So distance can be an intrusive reality, “stranding an asset”.  That’s what the math in 1989 did to Japanese real estate values, the extrapolated numbers meaning floor space in office buildings became at once “the most expensive on the planet” and unrealizable as convertible into cash; the asset became stranded in its bubble.  Still, the frothy days of 1989 must trigger a warm glow of nostalgia among the few able to take their profits and “exit” before the crash of 1990.  When the “bubble burst”, the effects were profound because, unlike the Dutch “tulip bubble” now understood to have had relatively little long-term effect on the wider economy of the Netherlands, in Japan, the crash in the real estate market trigged a cascade of consequences affecting the stock market, over-exposed banks and the wider economy.  In retrospect, that it was a bubble seems so obvious but then, in retrospect, much often does: In 1989, the cumulative value of the Japanese property market was four times that of the US (the latter with more than twice the population and 25 times the land mass); metropolitan Tokyo alone was worth more than the entire continental US and the 1.15 km² grounds of the Imperial Palace were valued at up to US$5.1 trillion (greater than the entire state of California).  So assets can become “stranded” in a number of ways but the concept is much the same: Whatever may appear the “book value”, if this number can never be translated to “real” economic value (not necessarily cash), that asset is stranded.  The Gaza strip is less distant from New York’s Trump Tower than the desirable real estate on an exoplanet a hundred light away but, with a population tiresomely showing no wish to go somewhere else so sea-front resorts can be built, it may as well be as distant.

Four episodes of Welcome to the N.H.K. (note the “Parental Warning” advisor stickers).

Among the most intriguing of the anime projects was Welcome to the N.H.K., based on a series of novellas by Tatsuhiko Takimoto san (b 1978).  Featuring a very anime-friendly cast of characters (with all that implies), as might be expected in a work about hikikomori, the text explored issues such as social isolation, depression, anxiety and existential dread but the novelty was the appearance of the mysterious N.H.K. (Nihon Hikikomori Kyoukai (Japan Hikikomori Association), a Masonic-like institution responsible for the increasing number of recluses “shut up” in their bedrooms.  The hook is the tale is that the N.H.K. is the shadowy creation of NHK (Nippon Hōsō Kyōkai (Japan Broadcasting Corporation)), the national public broadcaster.

What came to be called “Japan's Lost Decade” of the 1990s was marked severe economic stagnation, a “banking crisis” (bad loans left sitting on the books as if there was a prospect of repayment), a stock market collapse and deflation.  Between 1989-1991 the Nikkei 225 prime index would slump from near 39,000 to around 6,600 and in an era when many governments were fretting about apparently “entrenched” inflation, in Tokyo, what was being observed was deflation.  Central bankers at least know how to “fix” inflation (they engineer a recession), but deflation is a fabulous beast that convinces people not to spend because they know the same commodity will next week likely be cheaper; like the inverse process in an inflation-ridden state, deflation “feeds on itself” in a spiralling “feedback loop”.  Solutions proved elusive.  While central banks fighting inflation could continue raising interest rates until the pain of spending became too much for consumers, the concept of “negative interest rates” (ie one has to pay the bank to store one’s money) was of limited utility because savers’ “work arounds” to evade this would likely make the situation worse before it induced them to open the purse-strings.  Pulling the textbook off the shelf, after blowing off the dust, Japanese governments embarked on “fiscal stimulus programmes” that (with borrowed money) sustained banks continuing to loan to anyway insolvent borrowers, this creating both “zombie banks and “zombie companies”; institutions “not alive yet not quite dead”.  If anything is likely to stifle efficient resource reallocation in an economy, it’s having “zombies at scale”.  In a quirk of the uniqueness of the Japanese economy however, although government debt is now somewhere between 210-240% of GDP (the methods of calculation can vary) this is said “not to be a problem” because so much of the debt is in Yen and locally held (a benefit of all that saving induced by living in deflationary times).  Like the US government debt of US$40 trillion odd (120-135% of GDP), it may take some time before it’s confirmed whether or not these numbers are “a problem”.

Why I Became a Hikikomori (Shut-In), SillyPau explains.  Now we know.

All this happened in conjunction with GDP consistently under 1% and an aging population (a demographic trend that had become structural and continues to this day) and while those “salary men” in employment tended to remain so (although suffering “career stagnation”), the young, despite graduates being the most educated in history, faced what was dubbed the shūshoku hyōgaki (employment ice age), the jobs available for most being low paid, unstable and often non-permanent.  For a generation brought up with high expectations and a sense of unlimited possibilities, it was an unpleasant welcome to the new decade that would come to be called “the lost decade” and even that proved optimistic; by early in the twenty-first century the use had been updated to “lost decades” as the sluggishness persisted.  While it had come to be understood things were not going back to what they were in the happy days of 1989 (because what then was “was not real”), the young in particular still longed for something better.

Some continued their longing and some “just gave up”.  It was in the 1990s the “lost decade” produced the “lost generation” that came to be called the hikikomori, withdrawing from a society that seemed to offer little other than a dreary, meaningless existence.  By becoming recluses hardly ever leaving their bedrooms, maybe that was just another form of meaningless dreariness but at least it was on their terms and lent life some sense of “control”, illusory though that may have been.  According to Japanese researchers, the number of hikikomori had by 2024 grown to over a million and the phenomenon has, on a smaller scale, been noticed in other countries.  In Japan, having a million-odd modern-day hermits sitting in their bedrooms refusing to face the outside world remains unlikely to do much to stimulate the economy or the rapidly declining birth-rate.  Indeed, in mid-2026, the Ministry of Internal Affairs and Communications disclosed the population of domestic citizens had for the first time fallen below 120 million, a 0.76% decrease from the previous year; with 670,467 births against 1,593,475 deaths, deaths are outpacing births by more than two to one.

If something is happening in Japan, there will be anime documenting it in every aspect.  Titles include ReLIFE (2016), Recovery of an MMO Junkie (2017) and the ominous sounding Forbidden Deductions (2023).

Some have argued there is an element of technological determinism is all this.  Whether or not one chooses to label it “internet addiction”, there’s no doubt the ecosystem of the web and apps (especially hyper-realistic gaming) had made it possible as never before to lead a kind of fulfilling life without ever leaving one's bedroom.  With accommodating parents (an ample supply found in Japan) and a good internet connection, the bedroom can become one’s universe, a place without the awfulness one know lies beyond one’s four walls.  There is nothing new about those who either cannot cope with or have no wish to deal with the demands of modern society retreating to the margins but, for the first time in history, it has become possible for these recluses to exist in a rich, diverse, entertaining world that is wholly virtualized; relationships and even love affairs able to be conducted with AI (artificial intelligence) bots.  Because of the dynamics of the ways these bots can be constructed, many users (and by, implication, many hikikomori) probably find these relationships more satisfactory than anything experienced with one with a creature of flesh and blood; in many ways, for the tech industry, the COVID-19 pandemic was a “perfect storm”, contributing to some finding social isolation as “normalized”. The Japanese Government acknowledges hikikomori exists and defines it as something affecting people who have stayed at home for at least six months.

Hikikomori is discussed in the APA’s (American Psychiatric Association) DSM (Diagnostic and Statistical Manual of Mental Disorders) but not as a distinct mental disorder. Instead, it’s listed as a behavioral or psychosocial phenomenon that may occur in association with a variety of psychiatric conditions (and even, in some cases, without any diagnosable mental disorder).  In other words, the DSM treats hikikomori as a symptom rather than a pathology.  That would make sense to clinicians (if not all behavioural sociologists) and in DSM-5-TR (2022), hikikomori is mentioned in the section dealing with “Cultural Concepts of Distress”, the characteristics including (1) marked social withdrawal, (2) remaining at home (often confined to one room) for at least six months and (3) an association with significant functional impairment.  So, in the DSM, hikikomori is not classified as a separate diagnosis and clinicians are encouraged to consider whether the withdrawal is better explained by disorders such as: (1) autism spectrum disorder, (2) major depressive disorder, (3) schizophrenia spectrum disorders, (4) social anxiety disorder, (5) avoidant personality disorder or (6) OCD (obsessive-compulsive disorder).  If a patient seems not a good fit for any of those, helpfully, the DSM includes (7) other psychiatric illnesses and presumably, that cohort will be thought diagnostically the most interesting.  It would not be surprising if the profession settles on an acceptance of hikikomori as something transdiagnostic, a behavioral endpoint that can arise from various causes.

The Hikikomori: The Girl Who Couldn't Go Outside (2022) by Mark Vrankovich.

There is much thematic variation in hikikomori literature, ranging from the hopeful to the nihilistic.  There are also redemption tales.  In The Hikikomori: The Girl Who Couldn't Go Outside, Miko Nishimura san is a hikikomori who has become convinced she is the most insignificant person in Japan.  Crippled by anxiety, she never leaves her bedroom, occupying just about every waking moment playing racing games (she’s a most modern girl) on her computer.  However, a crisis ensues when the batteries in her wireless mouse die during a time when her parents are absent.  It’s made clear not many things could induce Miko san to leave the house but not being able to continue her gaming was such a rare  circumstance.  Miko san should of course have had spare batteries to hand (or, better still, used a wired mouse needing no batteries) but what’s done is done and can’t be undone and she knew she was compelled to make the terrifying trip to the shop to buy new batteries. As courageously she ventures forth, what unfolds is a tale intertwining contemporary Japanese culture, ancient magic powers and the finding of love.

Although in the west there’s a long tradition of “the recluse” (from the briefly installed Celestine V (circa 1212-1296; pope Jul-Dec 1294) to the film star Greta Garbo (1905–1990) and the multi-faceted Howard Hughes (1905–1976)) when in 1998 Dr Saitō san published his book, it seemed in the West fashionable to see hikikomori as something culturally specific, an example of one of the tradition-bound syndromes that delight writers who regard “Japanese weirdness” as the last acceptable form of the “orientalism” that was for decades a standard paradigm of academic and popular analysis of stuff east of Suez.  It’s still claimed (though increasingly unconvincingly) there are many of these “Japanese” syndromes relating to fields such as education, employment the family and attitude to psychiatric treatment but the modern view is that in these matters, between Japan and other cultures (certainly in East Asia), there are as many similarities as differences.  It has also become clear hikikomori–like behaviour exists in clinically significant numbers in a number of countries including South Korea, China, Hong Kong, Singapore, Spain, Italy, France, New Zealand, Canada, the US, Australia, the UK, Brazil and India.  Despite that, it is still most associated with Japan because it was there first identified (a la the “Spanish flu” process of 1919) but there’s no doubt the conjunction of the nation’s “lost decades” and the subsequent overlays of (1) the internet, (2) social media, (3) the COVID-19 pandemic and (4) consumer-packaged AI algorithms that made possible “life-like virtual relationships” created economic and social conditions that made the phenomenon both more prevalent and visible.
