This is a list of Japanese inventions and discoveries. The Japanese have made contributions across a number of scientific and technological domains. In particular, the country has played a crucial role in the digital revolution since the 20th century, with many modern revolutionary and widespread technologies in fields such as electronics and robotics introduced by Japanese inventors and entrepreneurs.
Arts [ edit ]
Comic book Adam L. Kern has suggested that kibyoshi, picture books from the late 18th century, may have been the world's first comic books. These graphical narratives share with modern manga humorous, satirical, and romantic themes.[1] Some works were mass-produced as serials using woodblock printing.[2]
Folding hand fan In ancient Japan, the first hand fans were oval and rigid fans, influenced greatly by Chinese fans. The earliest visual depiction of fans in Japan dates back to the 6th century AD, with burial tomb paintings showed drawings of fans. The folding fan was invented in Japan, with dates ranging from the 6th to 9th centuries and later exported to East Asia, Southeast Asia, and the West. Such a flourishing trade involving Japanese hand fans existed in the Ming dynasty times, when folding fans almost absolutely displaced the old rigid type in China.[3][4] Manga The history of manga has origins in scrolls dating back to the 12th century, and it is believed they represent the basis for the right-to-left reading style. During the Edo period (1603–1867), Toba Ehon embedded the concept of manga.[5] The word itself first came into common usage in 1798,[6] with the publication of works such as Santō Kyōden's picturebook Shiji no yukikai (1798),[7][8] and in the early 19th century with such works as Aikawa Minwa's Manga hyakujo (1814) and the Hokusai Manga books (1814–1834).[9][1]
Revolving stage Invented for the Kabuki theatre in Japan in the 18th century, the revolving stage was introduced into Western theater at the Residenz theatre in Munich in 1896 under the influence of japonism fever.[10]
Film and animation [ edit ]
Anime Japanese animation, or anime, today widely popular both in Japan and abroad, began in the early 20th century.
Postcyberpunk animation/film The first postcyberpunk media work in an animated/film format was Ghost in the Shell: Stand Alone Complex in 2002. It has been called "the most interesting, sustained postcyberpunk media work in existence."[12]
Architecture [ edit ]
Japanese castle Fortresses constructed primarily out of stone and wood used for military defence in strategic locations.[18]
Metabolism A post-war Japanese architectural movement developed by a wide variety of Japanese architects including Kiyonori Kikutake, Kisho Kurokawa and Fumihiko Maki, Metabolism aimed to fuse ideas about architectural megastructures with those of organic biological growth.[19]
Tahōtō Tahōtō is a form of Japanese pagoda found primarily at Esoteric Shingon and Tendai school Buddhist temples. Unlike most pagodas, it has two stories.[20]
Capsule hotel The first capsule hotel in the world opened in 1979 and was the Capsule Inn Osaka, located in the Umeda district of Osaka, Japan and designed by Kisho Kurokawa. From there, it spread to other cities within Japan. Since then, the concept has further spread to various other territories, including Belgium, China, Hong Kong, Iceland, India, Indonesia, and Poland.
Atmospheric sciences [ edit ]
Downburst Downbursts, strong ground-level wind systems that emanate from a point above and blow radially, were discovered by Ted Fujita.[21]
Fujita scale The first scale designed to measure tornado intensity, the Fujita scale, was first introduced by Ted Fujita (in collaboration with Allen Pearson) in 1971. The scale was widely adopted throughout the world until the development of the Enhanced Fujita scale.[22]
Fujiwhara effect The Fujiwhara effect is an atmospheric phenomenon where two nearby cyclonic vortices orbit each other and close the distance between the circulations of their corresponding low-pressure areas. The effect was first described by Sakuhei Fujiwhara in 1921.[23]
Jet stream Jet streams were first discovered by Japanese meteorologist Wasaburo Oishi by tracking ceiling balloons. However, Oishi's work largely went unnoticed outside Japan because it was published in Esperanto.[24][25]
Microburst The microburst was first discovered and identified as a small scale downburst affecting an area 4 km (2.5 mi) in diameter or less by Ted Fujita in 1974. Microbursts are recognized as capable of generating wind speeds higher than 270 km/h (170 mph). In addition, Fujita also discovered macrobursts and classified them as downbursts larger than 4 km (2.5 mi).[21]
Sports [ edit ]
Drifting competition In 1988, Keiichi Tsuchiya alongside Option magazine founder and chief editor Daijiro Inada organised the first contest specifically for sliding a car sideways. In 1996, Option organized the first contest outside Japan[26] which began to spread to other countries.
Keirin Started as a gambling sport in 1948 and became an Olympic sport in 2000.
Martial arts [ edit ]
Aikido Aikido was created and developed by Morihei Ueshiba in first half of the 20th century.
Judo It was created as a physical, mental and moral pedagogy in Japan, in 1882, by Kanō Jigorō.[27]
Jujutsu Jujutsu, the "way of yielding", is a collective name for Japanese martial art styles including unarmed and armed techniques. Jujutsu evolved among the samurai of feudal Japan as a method for defeating an armed and armored opponent without weapons. Due to the ineffectiveness of striking against an armored opponent, the most efficient methods for neutralizing an enemy took the form of pins, joint locks, and throws. These techniques were developed around the principle of using an attacker's energy against him, rather than directly opposing it.[28]
Karate It began as a common fighting system known as "ti" (or "te") among the pechin class of the Ryukyuans. There were few formal styles of ti, but rather many practitioners with their own methods. One surviving example is the Motobu-ryū school passed down from the Motobu family by Seikichi Uehara.[29] Early styles of karate are often generalized as Shuri-te, Naha-te, and Tomari-te, named after the three cities from which they emerged.[30]
Ninjutsu Developed by groups of people mainly from the Iga Province and Kōka, Shiga of Japan. Throughout history, many different schools (ryū) have taught their unique versions of ninjutsu. An example of these is the Togakure-ryū. This ryū was developed after a defeated samurai warrior called Daisuke Togakure escaped to the region of Iga. Later he came in contact with the warrior-monk Kain Doshi who taught him a new way of viewing life and the means of survival (ninjutsu).[31]
Okinawan martial arts In the 14th century, when the three kingdoms on Okinawa (Chūzan, Hokuzan, and Nanzan) entered into a tributary relationship with the Ming dynasty of China, Chinese Imperial envoys and other Chinese arrived, some of whom taught Chinese Chuan Fa (Kempo) to the Okinawans. The Okinawans combined Chinese Chuan Fa with the existing martial art of Te to form Tō-de ( 唐手 , Okinawan: Tū-dī , Tang hand) , sometimes called Okinawa-te ( 沖縄手 ) .[32] By the 18th century, different types of Te had developed in three different villages – Naha, Shuri, and Tomari. The styles were named Naha-te, Shuri-te, and Tomari-te, respectively. Practitioners from these three villages went on to develop modern karate.[33]
Sumo
Sumo is said to have started in the Heian period (794–1192). The imperial family watches sumo as a form of entertainment. It has evolved over the centuries with professional sumo wrestlers appearing in the Edo period (1603–1868).[34] The word sumo is written with the Chinese characters or Kanji of "mutual bruising."[35]
Video games [ edit ]
Dance Dance Revolution, one of the most successful Playing, one of the most successful rhythm games
PlayStation The first Sony PlayStation was invented by Ken Kutaragi. Research and development for the PlayStation began in 1990, headed by Kutaragi, a Sony engineer.[36]
Nintendo Gunpei Yokoi was the creator of the Game Boy and Virtual Boy and worked on Famicom (and NES), the Metroid series, Game Boy Pocket and did extensive work on the system we know today as the Nintendo Entertainment System (called the FamiCom in Japan).[37]
Active Time Battle Hiroyuki Ito introduced the "Active Time Battle" system in Final Fantasy IV (1991),[38] where the time-keeping system does not stop.[39] Square Co., Ltd. filed a United States patent application for the ATB system on March 16, 1992, under the title "Video game apparatus, method and device for controlling same" and was awarded the patent on February 21, 1995. On the battle screen, each character has an ATB meter that gradually fills, and the player is allowed to issue a command to that character once the meter is full.[40] The fact that enemies can attack or be attacked at any time is credited with injecting urgency and excitement into the combat system.[39]
Bullet hell The bullet hell or danmaku genre began to emerge in the early 1990s as 2D developers needed to find a way to compete with 3D games which were becoming increasingly popular at the time. Toaplan's Batsugun (1993) is considered to be the ancestor of the modern bullet hell genre.[45] The Touhou Project series is one of the most popular bullet hell franchises.
Platform game Space Panic, a 1980 arcade release, is sometimes credited as the first platform game.[50] It was clearly an influence on the genre, with gameplay centered on climbing ladders between different floors, a common element in many early platform games. Donkey Kong, an arcade game created by Nintendo, released in July 1981, was the first game that allowed players to jump over obstacles and across gaps, making it the first true platformer.[51]
Rhythm game Dance Aerobics was released in 1987, and allowed players to create music by stepping on Nintendo's Power Pad peripheral. It has been called the first rhythm-action game in retrospect,[58] although the 1996 title PaRappa the Rapper has also been deemed the first rhythm game, whose basic template forms the core of subsequent games in the genre. In 1997, Konami's Beatmania sparked an emergent market for rhythm games in Japan. The company's music division, Bemani, released a number of music games over the next several years.
Shoot 'em up Space Invaders is frequently cited as the "first" or "original" in the genre.[64][65] Space Invaders pitted the player against multiple enemies descending from the top of the screen at a constantly increasing speed.[65] As with subsequent shoot 'em ups of the time, the game was set in space as the available technology only permitted a black background. The game also introduced the idea of giving the player a number of "lives". Space Invaders was a massive commercial success, causing a coin shortage in Japan.[66][67] The following year, Namco's Galaxian took the genre further with more complex enemy patterns and richer graphics.[64][68]
Visual novel The visual novel genre is a type of Interactive fiction developed in Japan in the early 1990s. As the name suggests, visual novels typically have limited interactivity, as most player interaction is restricted to clicking text and graphics.[73]
Philosophy [ edit ]
Lean manufacturing A generic process management philosophy derived mostly from the Toyota Production System (TPS) (hence the term Toyotism is also prevalent) and identified as "Lean" only in the 1990s.[74][75]

Epinephrine (Adrenaline) Japanese chemist Jōkichi Takamine and his assistant Keizo Uenaka first discovered epinephrine in 1900.[83][84] In 1901 Takamine successfully isolated and purified the hormone from the adrenal glands of sheep and oxen.[85]
Esophagogastroduodenoscope Mutsuo Sugiura was a Japanese engineer famous for being the first to develop a Gastro-camera (a present-day Esophagogastroduodenoscope). His story was illustrated in the NHK TV documentary feature, "Project X: Challengers: The Development of a Gastro-camera Wholly Made in Japan". Sugiura graduated from Tokyo Polytechnic University in 1938 and then joined Olympus Corporation. While working at this company, he first developed an esophagogastroduodenoscope in 1950.
Frontier molecular orbital theory Kenichi Fukui developed and published a paper on Frontier molecular orbital theory in 1952.[86]

Food and food science [ edit ]
Umami Umami as a separate taste was first identified in 1908 by Kikunae Ikeda of the Tokyo Imperial University while researching the strong flavor in seaweed broth.[111]
Fortune cookie Although popular in Western Chinese restaurants, fortune cookies did not originate in China and are in fact rare there. They most likely originated from cookies made by Japanese immigrants to the United States in the late 19th or early 20th century. The Japanese version had a fortune, but not lucky numbers, and was commonly eaten with tea.[112]
Mathematics [ edit ]
Katsuyo Sampo (1712), tabulating binomial coefficients and Bernoulli numbers A page from Seki Kōwa's(1712), tabulating binomial coefficients and Bernoulli numbers
Bernoulli number Studied by Seki Kōwa and published after his death, in 1712. Jacob Bernoulli independently developed the concept in the same period, though his work was published a year later.[113][114][115]
Determinant In Japan, determinants were introduced to study elimination of variables in systems of higher-order algebraic equations. They used it to give shorthand representation for the resultant. The determinant as an independent function was first studied by Seki Kōwa in 1683.[115][116]
Elimination theory In 1683 (Kai-Fukudai-no-Hō), Seki Kōwa came up with elimination theory, based on resultant.[116] To express resultant, he developed the notion of determinant.[116]
Resultant In 1683 (Kai-Fukudai-no-Hō), Seki Kōwa came up with elimination theory, based on resultant. To express resultant, he developed the notion of determinant.[116]
Sangaku Japanese geometrical puzzles in Euclidean geometry on wooden tablets created during the Edo period (1603–1867) by members of all social classes. The Dutch Japanologist Isaac Titsingh first introduced sangaku to the West when he returned to Europe in the late 1790s after more than twenty years in the Far East.[120]

Double-coil bulb In 1921, Junichi Miura created the first double-coil bulb using a coiled coil tungsten filament while working for Hakunetsusha (a predecessor of Toshiba). At the time, machinery to mass-produce coiled coil filaments did not exist. Hakunetsusha developed a method to mass-produce coiled coil filaments by 1936.[136]
Tactile paving The original tactile paving was developed by Seiichi Miyake in 1965.[138] The paving was first introduced in a street in Okayama city, Japan, in 1967. Its use gradually spread in Japan and then around the world.
Audio technology [ edit ]
Physical modelling synthesis The first commercially available physical modelling synthesizer was Yamaha's VL-1 in 1994.[140]
Commercial digital recording Commercial digital recording was pioneered in Japan by NHK and Nippon Columbia, also known as Denon, in the 1960s. The first commercial digital recordings were released in 1971.[141]
Karaoke There are various disputes about who first invented the name karaoke (a Japanese word meaning "empty orchestra"). One claim is that the karaoke styled machine was invented by Japanese musician Daisuke Inoue[142] in Kobe, Japan, in 1971.[143][144]
Perpendicular recording Perpendicular recording was first demonstrated in the late 19th century by Danish scientist Valdemar Poulsen, who was also the first person to demonstrate that sound could be recorded magnetically. There weren't many advances in perpendicular recording until 1976 when Dr. Shun-ichi Iwasaki (president of the Tohoku Institute of Technology in Japan) verified the distinct density advantages in perpendicular recording. Then in 1978, Dr. T. Fujiwara began an intensive research and development program at the Toshiba Corporation that eventually resulted in the perfection of floppy disk media optimized for perpendicular recording and the first commercially available magnetic storage devices using the technique.[146]
Digital audio tape recorder In 1971, Heitaro Nakajima resigned from his post as head of NHK's Technical Research Laboratories and joined Sony. Four years earlier at NHK, Nakajima had commenced work on the digitization of sound and within two years had developed the first digital audio tape recorder.[147]
Direct-drive turntable Invented by Shuichi Obata, an engineer at Matsushita (now Panasonic),[148] based in Osaka.[149] In 1969, Matsushita released it as the SP-10, the first in their influential Technics series of turntables.[150] The Technics SL-1100, released in 1971, was adopted by early hip hop DJs for turntablism,[150] and the SL-1200 is still widely used by dance and hip hop DJs.[149]
Vowel-Consonant synthesis A type of hybrid Digital-analogue synthesis first employed by the early Casiotone keyboards in the early 1980s.
Batteries [ edit ]

Calculators [ edit ]
Pocket calculator The first portable calculators appeared in Japan in 1970, and were soon marketed around the world. These included the Sanyo ICC-0081 "Mini Calculator", the Canon Pocketronic, and the Sharp QT-8B "micro Compet". Sharp put in great efforts in size and power reduction and introduced in January 1971 the Sharp EL-8, also marketed as the Facit 1111, which was close to being a pocket calculator. It weighed about one pound, had a vacuum fluorescent display, and rechargeable NiCad batteries. The first truly pocket-sized electronic calculator was the Busicom LE-120A "HANDY", which was marketed early in 1971.[158]
Cameras [ edit ]
Chindōgu [ edit ]
Chindōgu is the Japanese art of inventing ingenious everyday gadgets that, on the face of it, seem like an ideal solution to a particular problem. However, Chindōgu has a distinctive feature: anyone actually attempting to use one of these inventions would find that it causes so many new problems, or such significant social embarrassment, that effectively it has no utility whatsoever. Thus, Chindōgu are sometimes described as "unuseless" – that is, they cannot be regarded as 'useless' in an absolute sense, since they do actually solve a problem; however, in practical terms, they cannot positively be called "useful." The term "Chindōgu" was coined by Kenji Kawakami.
Domestic appliances [ edit ]
Bladeless fan The first bladeless fan was patented by Toshiba in 1981.[161]
Bread machine The bread machine was developed and released in Japan in 1986 by the Matsushita Electric Industrial Company.

Inverter Air Conditioner Created by Toshiba in 1981 as an alternative to the standard home window Air conditioner, With the difference being in the compressor that is able to cool or warm a room to the intended temperature as quickly as possible while efficiently maintaining the desired temperature unlike standard AC units in which the compressor frequently turns off. Inverter AC units do not turn off only operating at a certain consistent speed while also being able to adjust its regularity.
Electronics [ edit ]
JFET (junction gate field-effect transistor) The first type of JFET was the static induction transistor (SIT), invented by Japanese engineers Jun-ichi Nishizawa and Y. Watanabe in 1950. The SIT is a type of JFET with a short channel length.[171]
Microcomputer for Automotive Engine Toshiba developed a close relationship with Ford for the supply of rectifier diodes for automobile AC alternators. In March 1971, Ford unexpectedly sent a set bulky specifications asking Toshiba to join a project to make an electronic engine control (EEC) in response to US Clean Air Act (sometimes known as the Muskie Act).[182]
Parametron Eiichi Goto invented the parametron in 1954 as an alternative to the vacuum tube. Early Japanese computers used parametrons until they were superseded by transistors.[187]
Radio-controlled wheel transmitter Futaba introduced the FP-T2F in 1974 that was the first to use a steering wheel onto a box transmitter.[189] KO Propo introduced the EX-1 in 1981 that integrated a wheel with a pistol grip with its trigger acting as the throttle. This became one of the two types of radio controlled transmitters currently for surface use.[190][191]
Stored-program transistor computer The ETL Mark III began development in 1954,[194] and was completed in 1956, created by the Electrotechnical Laboratory.[195] It was the first stored-program transistor computer.[195][196][197]
Videocassette recorder The first machines (the VP-1100 videocassette player and the VO-1700 videocassette recorder) to use the first videocassette format, U-matic, were introduced by Sony in 1971.[202]
Game controllers [ edit ]
D-pad In 1982, Nintendo's Gunpei Yokoi elaborated on the idea of a circular pad, shrinking it and altering the points into the familiar modern "cross" design for control of on-screen characters in their Donkey Kong handheld game. It came to be known as the "D-pad".[203] The design proved to be popular for subsequent Game & Watch titles. This particular design was patented. In 1984, the Japanese company Epoch created a handheld game system called the Epoch Game Pocket Computer. It featured a D-pad, but it was not popular for its time and soon faded. Initially intended to be a compact controller for the Game & Watch handheld games alongside the prior non-connected style pad, Nintendo realized that Gunpei's design would also be appropriate for regular consoles, and Nintendo made the D-pad the standard directional control for the hugely successful Nintendo Entertainment System under the name "+Control Pad".
Printing [ edit ]
What does a 3 team teaser pay?
A three-team 6-point teaser used to pay +180 which is equivalent to a regular parlay of three -244 favorites. As you will notice in the next...
3D printing In 1981, Hideo Kodama of Nagoya Municipal Industrial Research Institute invented two additive methods for fabricating three-dimensional plastic models with photo-hardening thermoset polymer, where the UV exposure area is controlled by a mask pattern or a scanning fiber transmitter.[205][206]
Hydrographics Hydrographics, also known variously as immersion printing, water transfer printing, water transfer imaging, hydro dipping, or cubic printing has an somewhat fuzzy history. Three different Japanese companies are given credit for its invention. Taica Corporation claims to have invented cubic printing in 1974. However, the earliest hydrographic patent was filed by Motoyasu Nakanishi of Kabushiki Kaisha Cubic Engineering in 1982.[207]
Robotics [ edit ]
Android Waseda University initiated the WABOT project in 1967, and in 1972 completed the WABOT-1, the world's first full-scale humanoid intelligent robot.[208] Its limb control system allowed it to walk with the lower limbs, and to grip and transport objects with hands, using tactile sensors. Its vision system allowed it to measure distances and directions to objects using external receptors, artificial eyes and ears. And its conversation system allowed it to communicate with a person in Japanese, with an artificial mouth. This made it the first android.[209][210]
DER-01, a Japanese actroid (an android intended to be very visually similar to humans)
DER 01 was developed by a Japanese research group, The Intelligent Robotics Lab, directed by Hiroshi Ishiguro at Osaka University, and Kokoro Co., Ltd. The Actroid is a humanoid robot with strong visual human-likeness developed by Osaka University and manufactured by Kokoro Company Ltd. (the animatronics division of Sanrio). It was first unveiled at the 2003 International Robot Exposition in Tokyo, Japan. The Actroid woman is a pioneer example of a real machine similar to imagined machines called by the science fiction terms android or gynoid, so far used only for fictional robots. It can mimic such lifelike functions as blinking, speaking, and breathing. The "Repliee" models are interactive robots with the ability to recognise and process speech and respond in kind.[211][212][213]
Karakuri puppet Karakuri puppets ( からくり人形 , karakuri ningyō ) are traditional Japanese mechanized puppets or automata, originally made from the 17th century to the 19th century. The word karakuri means "mechanisms" or "trick".[214] The dolls' gestures provided a form of entertainment. Three main types of karakuri exist. Butai karakuri ( 舞台からくり , stage karakuri) were used in theatre. Zashiki karakuri ( 座敷からくり , tatami room karakuri) were small and used in homes. Dashi karakuri ( 山車からくり , festival car karakuri) were used in religious festivals, where the puppets were used to perform reenactments of traditional myths and legends.
Robotic exoskeleton for motion support (medicine) The first HAL prototype was proposed by Yoshiyuki Sankai, a professor at Tsukuba University.[215] Fascinated with robots since he was in the third grade, Sankai had striven to make a robotic suit in order "to support humans." In 1989, after receiving his Ph.D. in robotics, he began the development of HAL. Sankai spent three years, from 1990 to 1993, mapping out the neurons that govern leg movement. It took him and his team an additional four years to make a prototype of the hardware.[216]

Myriad year clock The Myriad year clock (万年自鳴鐘 Mannen Jimeishou, lit. Ten-Thousand Year Self-ringing Bell), was a universal clock designed by the Japanese inventor Hisashige Tanaka in 1851. It belongs to the category of Japanese clocks called Wadokei.[241]
Quartz wristwatch The world's first quartz wristwatch was revealed in 1967: the prototype of the Astron revealed by Seiko in Japan, where it was in development since 1958. It was eventually released to the public in 1969.[242]
Spring Drive A watch movement which was first conceived by Yoshikazu Akahane working for Seiko in 1977 and was patented in 1982. It features a true continuously sweeping second hand, rather than the traditional beats per time unit, as seen with traditional mechanical and most quartz watches.[243]
Transportation [ edit ]
Self-driving car The first self-driving car that did not rely upon rails or wires under the road is designed by the Tsukuba Mechanical Engineering Laboratory in 1977. The car was equipped with two cameras that used analog computer technology for signal processing.[246][247]
Hybrid electric vehicle The first commercial hybrid vehicle was the Toyota Prius launched in 1997.[249]
Hydrogen car In 2014, Toyota launched the first production hydrogen fuel cell vehicle, the Toyota Mirai.[250] The Mirai has a range of 312 miles (502 km) and takes about five minutes to refuel. The initial sale price was roughly 7 million yen ($69,000).
Kei car A category of small automobiles, including passenger cars, vans, and pickup trucks. They are designed to exploit local tax and insurance relaxations, and in more rural areas are exempted from the requirement to certify that adequate parking is available for the vehicle.[251][252]
Rickshaw A two or three-wheeled passenger cart seating one or two people that serves as a mode of human-powered transport pulled by a runner draws a two-wheeled cart. The rickshaws was invented in Japan around 1869,[253][254] after the lifting of a ban on wheeled vehicles from the Tokugawa period (1603–1868),[255] and at the beginning of a rapid period of technical advancement across the Japanese archipelago.[254][256]
Spiral escalator Mitsubishi Electric unveiled the world's first practical spiral escalator in 1985. Spiral escalators have the advantage of taking up less space than their conventional counterparts.[257]
Inverter-Controlled High-Speed Gearless Elevator The insulated gate bipolar transistors (IGBTs) realized increased switching frequency and reduced magnetic noise in the motor, which eliminated the need for a filter circuit and resulted in a more compact system. The IGBT also allowed the development of a small, highly integrated and highly sophisticated all-digital control device, consisting of the combination of a high-speed processor, specially customized gate arrays, and a circuit capable of controlling large currents of several kHz. Today, the inverter-controlled gearless drive system is applied in high-speed elevators worldwide.[258]
Personal watercraft Kawasaki were the first to develop stand-up personall watercraft under their trademark Jet Ski. While experimentation with personal watercraft preceded this. The Jet Ski was the first commercially successful and practical PWC.[259]
Military [ edit ]
Amphibious assault ship Imperial Japanese Army Akitsu maru is regarded as the first of the kind.
Dock landing ship Imperial Japanese Army Shinshu maru is regarded as the first of the kind.
Fire balloon A fire balloon, or balloon bomb, was an experimental weapon launched by Japan from 1944 to 1945, during World War II.[261]
Katana The katana were traditional Japanese swords used by samurai warriors of ancient and feudal Japan. The swords originated in the Muromachi period (1392–1573) as a result of changing battle conditions requiring faster response times. The katana facilitated this by being worn with the blade facing up, which allowed the samurai to draw their blade and slash at their enemy in a single motion. Previously, the curved sword of the samurai was worn with the blade facing down. The ability to draw and cut in one motion also became increasingly useful in the daily life of the samurai.[262]
Shuriken The shuriken was invented during the Gosannen War as a concealed weapon, primarily for the purpose of distracting a target.[263]
Wireless transmission [ edit ]
Writing and correction implements [ edit ]
Correction tape Correction tape was invented in 1989 by the Japanese product manufacturer Seed. It is an alternative to correction fluid.[266]
Gel pen The gel pen was invented in 1984 by the Sakura Color Products Corporation of Osaka.[267]
Rollerball pen The first rollerball pen was invented in 1963 by the Japanese company Ohto.[268]
Other [ edit ]
Artificial snowflake The first artificial snowflake was created by Ukichiro Nakaya in 1936, three years after his first attempt.[269]
Canned coffee Canned coffee was invented in 1965 by Miura Yoshitake, a coffee shop owner in Hamada, Shimane Prefecture, Japan.[270]
Emoji The first emoji was created in 1998 or 1999 in Japan by Shigetaka Kurita.[271]
Fake food Simulated food was invented after Japan's surrender ending World War II in 1945. Westerners traveling to Japan had trouble reading Japanese menus and in response, Japanese artisans and candlemakers created wax food so foreigners could easily order something that looked appetizing.[272]
Go, modern rules of Though the game originated in China, free opening of the game as it is played globally began in the 16th century Japan.
Imageboard The first imageboards were created in Japan. Later imageboards such as 2chan would be created.[273]
Yoshizawa–Randlett system The Yoshizawa–Randlett system is a diagramming system used for origami models. It was first developed by Akira Yoshizawa in 1954. It was later improved upon by Samuel Randlett and Robert Harbin.[274] Textboard Textboards like imageboards were invented in Japan. However, unlike imageboards, textboards are relatively unknown outside Japan.[273]
