Koei Tecmo Holdings Co., Ltd.[a][2] is a Japanese video game, amusement and animeholding company created in2009 by the merger ofKoei andTecmo.[3] The holding company itself, as well as its subsdiaries and divisions, were known as Tecmo Koei until the names were reversed to Koei Tecmo in 2014 without any change to the logo.
Koei Tecmo Holdings owns many companies, the biggest one of them being is its flagshipvideo game developer andpublisher Koei Tecmo Games that was founded in 1978 asKoei. Since 2010, Koei Tecmo Games has been the owner of the previous Koei and Tecmo franchises, and occasionally used both brand names on new video games for marketing purposes until 2016.
The company is best known for theirAtelier,Dead or Alive,Dynasty Warriors,Samurai Warriors,Fatal Frame,Monster Rancher,Ninja Gaiden,Nioh,Nobunaga's Ambition andRomance of the Three Kingdoms franchises. They are also known for their work on external video game franchises, namely onSquare Enix'sFinal Fantasy andNintendo'sFire Emblem.

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 duoYōichi [ja] andKeiko Erikawa. Yōichi was a student atKeio University, and when his family's ruraldyestuffs business failed he decided to pursue his interest in programming. The company was (and, as Koei Tecmo, still is) located in theHiyoshi area ofYokohama along with Yoichi's alma mater, and the company's name is simply aspoonerism of the school's.
The company initially focused onpersonal computer sales and made-to-order businesssoftware. In 1983 it releasedNobunaga's Ambition (信長の野望Nobunaga no Yabō), a historicalstrategy game set during theSengoku period ofJapanese history. The game went on to receive numerous awards, and Koei produced several more such games set against the backdrop of world history, includingRomance of the Three Kingdoms, set during theThree Kingdoms period ofChinese history, andUncharted Waters (大航海時代Dai Kōkai Jidai; lit.Great Navigation Era), set inPortugal during theAge of Exploration.
In 1988, Koei established aNorth Americansubsidiary,Koei Corporation, inCalifornia. This subsidiary localized Koei games for export to all territories outside Japan, as well as producing original games and concepts with the leadership of designerStieg Hedlund, likeLiberty or Death,Celtic Tales: Balor of the Evil Eye, andGemfire. After Hedlund's departure, this subsidiary ceased game development in 1995, focusing instead on localization, sales and marketing.
ACanadian subsidiary,Koei Canada, Inc. was established in early 2001, and aEuropean subsidiary,Koei Limited was established in early 2003 inHertfordshire,United Kingdom. In 2004, aLithuanian subsidiary was formed.[4]

Tecmo, Ltd.,[b] formerly known asTehkan Ltd.,[c] was founded by Yoshihito Kakihara on July 31, 1967,[5] as a supplier of cleaning equipment.[6] Two years later, in 1969, it started to sellamusement equipment. Tecmo had its headquarters inKudankita,Chiyoda,Tokyo.[7] Tecmo's United States offices were located inTorrance, California.[8]
In March 1981, a U.S. division was inaugurated asU.S. Tehkan, Inc.. A month later, in April 1981, Tehkan released in Japan its first arcade video game titledPleiades (which was distributed in America byCenturi). When it was still called Tehkan, the company also released such classic games asBomb Jack andTehkan World Cup. On January 8, 1986, Tehkan officially changed its name to Tecmo. In 1989 Tecmo was named as co-defendant in a lawsuit, whenIndianapolis Coltsrunning backEric Dickerson sued theNFLPA over use of his likeness in the gameTecmo Bowl.[9]
In January 2006, Tecmo president, Junji Nakamura, resigns from the company while Yoshimi Yasuda was named his successor.[10]
In 2006, Founder Yoshihito Kakihara died ofinterstitial pneumonia.[11]
On June 3, 2008, Team Ninja headTomonobu 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".[12] 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.[13]
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.[14][15] Upon hearing this news on August 31, Kenji Matsubara, President and COO of Koei, called a board meeting for the next day, September 1.[16] 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,[17] and later that same day announced plans to merge with Koei.[16][18][19]
To survive and compete in this market, we need to have some sort of scale - it's critical. And that's the trigger of this consolidation. Square Enix had made an offer, and we had started a discussion with Tecmo as well. But Tecmo's founding family and Koei's founders' family have actually had a good relationship for many years, which is why we were able to make a deal in such a short time! We started the discussion on September 1st, and it was agreed two days after! Tecmo's founders and management team understands that while it is nice to stand alone, it is risky, and scale is critical.
— Kenji Matsubara[20]
In November, the companies announced their specific plan of action, to complete the merger on April 1, 2009, forming Tecmo Koei Holdings.[21] 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.[22] Effissimo Capital Management Pte, Tecmo's second-largest shareholder at 17.6%, openly opposed the merger.[23] 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 they may seek to sell their shares.[24] 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."[25] On February 12, Kenji Matsubara liquidated KOEI FranceSAS.[26] 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.[27]
Despite these misgivings, the holding company formed on April 1, 2009, as planned.[28] Kenji Matsubara became CEO of the new company, and former Tecmo CEO Yasuharu Kakihara became board chairman.[29] 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.[30]
On June 23, 2009, Tecmo Koei announced a planned restructure of its international subsidiaries.[31][32] Koei Europe was renamedTecmo Koei Europe in 2009 and became the first subsidiary to publish games under the new moniker,[33] starting withNinja Gaiden Sigma 2.[34] In August 2009 Tecmo Koei announced that it was setting up a subsidiary in Hanoi, Vietnam.[35] In January 2010, Tecmo's sole subsidiary, the American Tecmo Inc., and Koei's American branch, Koei Corporation, were moved under a newly formedTecmo 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 theEntertainment Software Association (ESA) announced that Tecmo Koei was now a member.[36]
On April 1, 2010, Tecmo was declared disbanded in Japan.[37][38] Koei absorbed Tecmo the same day to becomeTecmo Koei Games.[39][40] 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.[41][40] Koei Singapore was also re-branded as Tecmo Koei.[42]
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.[43]
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.[41][40]
