Initially operating from a single-room apartment, Technos was founded in 1981 by three staff members of Data East. Their first game was Minky Monkey, released in 1982. Many of Technos Japan's earlier games were often published or distributed by other companies, particularly Data East (as was the case with Karate Champ) and Taito, as Technos at the time did not have the economical resource to distribute their own games at first.
Nekketsu Kōha Kunio-kun ("Hot Blooded Tough Guy Kunio"), a side-scrolling beat-em-up released in 1986 about a high school student who fought thugs and delinquents from other schools, was the company's first big hit in Japan. Kunio-kun was released in the west as Renegade with the game's graphics changed to make the game marketable in the overseas market. Technos would then produced an Famicom/NES version of the game, which would be Technos' first game for the home console market. Technos Japan's subsequent arcade beat-em-up, Double Dragon, was a big success worldwide when it was released in 1987, which also resulted in an NES version of the game produced, as well as licensed versions produced by other companies for various platforms.
The success of Kunio-kun led to the production of numerous spin-offs and sequels starring the same character produced for the 8-bit Famicom game in Japan and later for the Game Boy and Super Famicom, resulting in more than twenty games starring Kunio by the mid-1990s, many of which were rule-bending sports games. A few Kunio-kun games were localized for the North American market; namely Super Dodge Ball, River City Ransom (considered by critics to be a cult classic) and Nintendo World Cup, but none maintain any connection with each other. Technos would attempt to remedy this by attempting to localize several Kunio-kun under the Crash 'n the Boys label, but only Crash 'n the Boys: Street Challenge was released (the game's ending features a teaser for Ice Challenge, which was unreleased).
Technos also released two arcade sequels to Double Dragon: Double Dragon II: The Revenge in 1988 and Double Dragon 3: The Rosetta Stone in 1990 (the latter was developed by an external development team at East Technology), and produced the respective NES versions of those games, as well as Super Double Dragon in 1992, an original installment for the Super NES. An American-produced Double Dragon animated series and a live-action film were also made as well.
Outside the Double Dragon and Kunio-kun games, Technos produced a few original games for the arcade and home markets such as U.S. Championship V'Ball, The Combatribes and Shadow Force, as well as two WWF arcade games (WWF Superstars and WWF Wrestlefest), but most of these games did not achieve the same kind of success that Kunio-kun and Double Dragon achieved.
By 1996, Technos Japan declared bankruptcy and went out of business. The company's last few games were produced for the Neo Geo hardware, which includes a Double Dragon fighting game based on the movie, the anime-based fighter Voltage Fighter Gowcaizer and a Neo-Geo sequel to Super Dodge Ball (which was officially released only in MVS format).
Since Technos Japan's closure, a company called Million (a company founded by former CEO Kunio Taki and Kunio-kun series producer Mitsuhiro Yoshida) has purchased the former intellectual properties of Technos Japan and are producing new games based on them. Million has produced Super Dodge Ball Advance, Double Dragon Advance and River City Ransom EX for the Game Boy Advance, Super Dodgeball Brawlers for the Nintendo DS, and Super Dodge Ball for Japanese mobile phones.
Technos Japan had a subsidiary in the U.S. called American Technos Inc., which was located at Cupertino, California. American Technos was formed in 1987, shortly after release of Double Dragon at the arcades and published all of Technos Japan's arcade games in North America beginning with Double Dragon II: The Revenge. While the majority of Technos Japan's console games were still licensed to other companies such as Tradewest (Double Dragon), Acclaim (Double Dragon II and III), CSG Imagesoft (Super Dodge Ball) and even Nintendo (Super Spike V'Ball and Nintendo World Cup), American Technos also managed to published a few console games: namely River City Ransom and Crash 'n the Boys: Street Challenge for the NES, Super Double Dragon (co-published with Tradewest) and Combatribes for the Super NES and Geom Cube for the PlayStation. American Technos also published Super Bowling (developed by Athena) and Super Pinball: Behind the Mask (developed by Meldac/KAZe) for the Super NES and the helicopter game Strike Point for the PlayStation. American Technos was still operating after Technos Japan's demise until sometime during the late 1990s.
