Data East Corporation (株式会社データイースト Dēta Īsuto Kabushikigaisha?) also abbreviated as DECO, was a Japanese video game and electronic engineering company. The company was in operation from 1976 to 2003, when it declared bankruptcy. Its main headquarters were located in Suginami, Tokyo, The American subsidiary, Data East USA, had been headquartered in San Jose, California.
Data East was founded by Tetsuo Fukuda (福田 哲夫 Fukuda Tetsuo?) on April 20, 1976  as an electronic engineering company which focused on integrating interchangeable tapes inside arcade game devices, allowing video games operators to replace a game from a machine without having to replace the cabinet itself. Realizing the money that could be made within the interactive content, Data East developed in 1977 its first arcade game Jack Lot.  This was followed in 1978 by Super Break, a clone of Atari's Breakout and Space Fighters, a clone of Taito's Space Invaders. In 1979, Data East released its first original game, Nice On, which was released exclusively in Japan. Data East established a U.S. division in 1979, after its chief competitors Sega and Taito had already established a market presence. In 1980, Data East published Astro Fighter which became its first major arcade title. While making games, Data East released a series of interchangeable systems compatible with its arcade games, notably the DECO Cassette System and the Multi Conversion Kit, but these products soon became infamous among its users due to its numerous technical problems.
In 1981, three staff members of Data East founded Technōs Japan, who then supported Data East for a while before becoming completely independent.
Data East proved to be one of the more successful and long-lasting companies in the business, surviving the video game crash of 1983 in reasonably good shape and going on to release dozens of games for both arcade and home console systems over the next two decades. Some of its most famous coin-op arcade games from its 1980s heyday included Karate Champ, Heavy Barrel, BurgerTime, Bad Dudes Vs. Dragon Ninja, Sly Spy, RoboCop, Bump 'n' Jump, Trio The Punch – Never Forget Me..., Karnov and Atomic Runner Chelnov. Karate Champ was the first successful fighting game, due to being one of the most influential to modern fighting game standards. It was also the subject of the litigation Data East USA, Inc. v. Epyx, Inc., in which Data East alleged that Epyx's International Karate infringed the copyright in Karate Champ.
Data East also purchased licenses to manufacture and sell arcade games created by other companies. Its most successful licensed games included Kid Niki: Radical Ninja, Kung Fu Master and Vigilante, all licensed from Irem, and Commando, licensed from Capcom. It had a brief stint as a Neo-Geo arcade licensee in the mid-1990s, starting with Spinmaster.
Data East also made pinball machines from 1987 through 1994, and included innovations such as the first pinball to have stereo sound (Laser War), the first usage of a small dot matrix display in Checkpoint along with the first usage of a big DMD (192x64) in Maverick. In designing pinball machines they showed a strong preference for using high-profile (but expensive) licensed properties, rather than creating totally original machines, which did not help the financial difficulties the company began experiencing from 1990 on. Some of the properties that Data East licensed for its pinball machines included Guns N' Roses, Star Wars, Back to the Future, Batman, RoboCop, The Simpsons, and Teenage Mutant Ninja Turtles. Data East is the only company that manufactured custom pinball games (e.g. for Aaron Spelling, the movie Richie Rich, or Michael Jordan), though these were basically mods of existing or soon to be released pinball machines (e.g. Lethal Weapon 3). The pinball division was created in 1985 by purchasing the pinball division of Stern Electronics and its factory and assets. Amidst plummeting sales across the entire pinball market, Data East chose to exit the pinball business and sold the factory to Sega in 1994. At the time of the buyout by Sega, Data East Pinball was the world's second-largest pinball manufacturer, holding 25 percent of the market.
Although video games represented the majority of the company's revenue, Data East had always been involved in engineering. Outside of video games, Data East produced image transmission equipment, data communication adapters for satellite phones from NTT DoCoMo, and development of electrocardiogram equipment for ambulances. According to the company's website, its Datafax product, released in 1983, was the world's first portable fax machine. 
By the end of the 1990s, the company's American division, Data East USA, had been liquidated and Data East had ceased to exist outside of Japan. The Japanese parent company itself withdrew entirely from the arcade industry in 1998 and had accumulated a debt estimated at 3.3 billion yen. Unable to escape its mounting financial problems, Data East filed for reorganization in 1999 and stopped making video games altogether. For the following three and a half years, Data East sold negative ion generators and licensed some of its old video games to other companies; all of this in hope of collecting enough money to be able to make video games again and return to the competition. Nonetheless, the company's restructuring efforts were not enough to put back the financial problems brought by the 1990s and in April 2003, Data East filed for bankruptcy and was finally declared bankrupt by a Tokyo district court on June 25, 2003. The news was released to the public two weeks later, on July 8.
Most of Data East's intellectual properties were acquired in February 2004 by G-Mode, a Japanese mobile game content provider. However some Data East's important assets, including Karnov, Chelnov, the Vapor Trail trilogy and the Glory of Heracles series are owned by Paon Corporation instead of G-Mode. Likewise, G-Mode does not own rights to the Metal Max series and the Tantei Jingūji Saburō series which were retained by Crea-Tech and WorkJam respectively. RoboCop (at least, the arcade version) was acquired by D4 Enterprise in September 2010.  The remaining properties of Data East are regrouped under a shell corporation called Takutoron Corporation maintained by founder Tetsuo Fukuda. Takutoron has since sued Nintendo twice for patent infringement, but both cases were dismissed.
In September 2009, Majesco Entertainment has announced that it would release a collection of arcade games from Data East called Data East Arcade Classics for the Wii console under license from G-Mode.
