Independent era Koei Koei Co., Ltd. (株式会社コーエー
Kabushiki gaisha Kōē, formerly 光栄 (Kōei)) was founded in July 1978 by husband-and-wife duo and
Keiko Erikawa. Yōichi was a student at
Keio University, and when his family's rural
dyestuffs business failed he decided to pursue his interest in programming. The company was (and, as Koei Tecmo, still is) located in the
Hiyoshi area of
Yokohama along with Yoichi's alma mater, and the company's name is simply a
spoonerism of the school's. The company initially focused on
personal computer sales and made-to-order business
software. In 1983 it released ''
Nobunaga's Ambition (信長の野望 Nobunaga no Yabō
), a historical strategy game set during the Sengoku period of Japanese history. The game went on to receive numerous awards, and Koei produced several more such games set against the backdrop of world history, including Romance of the Three Kingdoms, set during the Three Kingdoms period of Chinese history, and Uncharted Waters (大航海時代 Dai Kōkai Jidai
; lit. Great Navigation Era''), set in
Portugal during the
Age of Exploration. In 1988, Koei established a
North American
subsidiary,
Koei Corporation, in
California. This subsidiary localized Koei games for export to all territories outside Japan, as well as producing original games and concepts with the leadership of designer
Stieg Hedlund, like
Liberty or Death,
Celtic Tales: Balor of the Evil Eye, and
Gemfire. After Hedlund's departure, this subsidiary ceased game development in 1995, focusing instead on localization, sales and marketing. A
Canadian subsidiary,
Koei Canada, Inc. was established in early 2001, and a
European subsidiary,
Koei Limited was established in early 2003 in
Hertfordshire,
United Kingdom. In 2004, a
Lithuanian subsidiary was formed.
Tecmo formerly known as was founded by Yoshihito Kakihara on July 31, 1967, as a supplier of cleaning equipment. Two years later, in 1969, it started to sell
amusement equipment. Tecmo had its headquarters in
Kudankita,
Chiyoda,
Tokyo. Tecmo's United States offices were located in
Torrance, California. In March 1981, a U.S. division was inaugurated as
U.S. Tehkan, Inc.. A month later, in April 1981, Tehkan released in Japan its first arcade video game titled
Pleiades (which was distributed in America by
Centuri). When it was still called Tehkan, the company also released such classic games as
Bomb Jack and
Tehkan World Cup. On January 8, 1986, Tehkan officially changed its name to Tecmo. In 1989 Tecmo was named as co-defendant in a lawsuit, when
Indianapolis Colts running back Eric Dickerson sued the
NFLPA over use of his likeness in the game
Tecmo Bowl. In January 2006, Tecmo president, Junji Nakamura, resigns from the company while Yoshimi Yasuda was named his successor. In 2006, Founder Yoshihito Kakihara died of
interstitial pneumonia. On June 3, 2008, Team Ninja head
Tomonobu Itagaki resigned from the company and filed a 145 million yen ($1.3 million) lawsuit against Yoshimi Yasuda for "unpaid completion bonuses" and "emotional distress". This was followed by another lawsuit filed on June 16, 2008, by two plaintiffs on behalf of Tecmo's 300 employees for unpaid wages amounting to ¥8.3 million.
Merger and reorganization On August 20, 2008, Tecmo announced the resignation of president Yoshimi Yasuda, to be replaced by current chairman of the board Yasuharu Kakihara as of September 1. On August 28,
Square Enix announced plans for a friendly takeover of Tecmo by purchasing shares at a 30 percent premium with a total bid of
¥22.3 billion. They gave Tecmo until September 4 to either accept or reject the proposal. Upon hearing this news on August 31, Kenji Matsubara, President and COO of Koei, called a board meeting for the next day, September 1. The board discussed the possibility of a merger with Tecmo, and began discussions with Tecmo that same day. On September 4, 2008, Tecmo officially declined Square Enix's proposal, and later that same day announced plans to merge with Koei. In November, the companies announced their specific plan of action, to complete the merger on April 1, 2009, forming Tecmo Koei Holdings. Koei stock was to be exchanged for Tecmo Koei stock at a rate of 1:1, and Tecmo stock exchanged at .9:1, giving Koei shareholders, in total, a three-quarter stake in the new company. Though the combined profits in 2007 were 8.5 billion yen, they anticipated that the merged company would net over 16 billion yen in the fiscal year ending March 2012. Effissimo Capital Management Pte, Tecmo's second-largest shareholder at 17.6%, openly opposed the merger. On January 26, 2009, the shareholders for both Koei and Tecmo reached separate agreements in favor of the merger. Effissimo raised some dissent during the meeting, and implied it may seek to sell its shares. Effissimo's director Takashi Kosaka stated "We have not had sufficient information from the company to make a judgment on the merger, such as the feasibility of their plan to raise shareholder value." On February 12, Kenji Matsubara liquidated KOEI France
SAS. On February 13, Tecmo announced it had received a repurchase claim (a request for the company to buy stock back) from a major shareholder, 15.64% of the stock (3,890,700 shares) from a shareholder that stood in opposition to the firm's upcoming merger with Koei. While the requesting shareholder was not mentioned,
Reuters stated that it was likely Effissimo. Despite these misgivings, the holding company formed on April 1, 2009, as planned. Kenji Matsubara became CEO of the new company, and former Tecmo CEO Yasuharu Kakihara became board chairman. As of May 26, Tecmo Koei had still not reached an agreement with Effissimo, prompting the investment fund to seek mediation with the Tokyo District Court. While Tecmo Koei favored a stock value in the mid-600 yen range, Effissimo was expected to ask for at least 900, in part due to the rejected Square Enix offer of 920 per share. On June 23, 2009, Tecmo Koei announced a planned restructure of its international subsidiaries. Koei Europe was renamed
Tecmo Koei Europe in 2009 and became the first subsidiary to publish games under the new moniker, starting with
Ninja Gaiden Sigma 2. In August 2009 Tecmo Koei announced that it was setting up a subsidiary in Hanoi, Vietnam. In January 2010, Tecmo's sole subsidiary, the American Tecmo Inc., and Koei's American branch, Koei Corporation, were moved under a newly formed
Tecmo Koei America Corporation, itself a direct subsidiary to Tecmo Koei Holdings. Koei's Canadian, Korean, and Taiwanese subsidiaries were re-branded Tecmo Koei, and also moved to direct subsidiaries of the holding company. Later that month the
Entertainment Software Association (ESA) announced that Tecmo Koei was now a member. On April 1, 2010, Tecmo was declared disbanded in Japan. Koei absorbed Tecmo the same day to become
Tecmo Koei Games. The development divisions of both companies were spun-out into separate subsidiaries of Tecmo Koei Games, created specifically for the planning and development of software.
As Tecmo Koei The continued operating loss prompted Kenji Matsubara, the former president and CEO of both Tecmo Koei Holdings and Tecmo Koei Games label, to render his resignation in November 2010. Yoichi Erikawa, co-founder of Koei, took over the four positions vacated by Matsubara. On February 8, 2011, Tecmo Koei Holdings announced that the new individual developers Tecmo and Koei that were formed in March 2010 would be merged into Tecmo Koei Games in April 2011, though the company would continue to create games in the future under the Tecmo and Koei brands. On February 18, 2016, Koei Tecmo announced a second reorganization of the company, to support the expansion of the company. Brand names Team Tachyon, Koei and Tecmo, amongst others, were dropped. On February 10, 2025, Koei Tecmo announced that Hisashi Koinuma, who currently serves as the representative director and executive vice president of Koei Tecmo Holdings, will replace Yoichi Erikawa as company president and CEO, effective April 1, 2025. Yoichi Erikawa, co-founder of Koei and more commonly known as Kou Shibusawa, will transition to representative director and chairman of Koei Tecmo Holdings. His wife Keiko Erikawa, also a co-founder, will transition from representative director and chairman to director and chairman emeritus, as well as representative director and president of Koei Tecmo Corporate Finance, which will be established on April 1. Koei Tecmo Corporate Finance will take over the investment functions of Koei Tecmo Games through an absorption-type company split. The move aims to strengthen governance related to investments and improve cash management across the company. == Subsidiaries/divisions ==
