Tomonobu Itagaki (板垣 伴信, Itagaki Tomonobu) (April 1, 1967 – October 16, 2025) was a Japanese video game designer best known for creating the Dead or Alive series and also reviving the Ninja Gaiden franchise in 2004. In 2009, he was chosen by IGN as one of the top 100 game creators of all time. Joining Tecmo in 1992, Itagaki produced two video game franchises that were commercial successes and earned him several promotions; he headed Tecmo's development team, Team Ninja, and sat on the executive board. He left the company in June 2008 after 16 years of service, filing a lawsuit against it for withholding bonus pay. He formed a new company Valhalla Game Studios with several Team Ninja members and released Devil's Third. The company was dissolved in December 2021, although he formed Itagaki Games shortly thereafter. == Early life == Tomonobu Itagaki was born in Tokyo on April 1, 1967. Itagaki later graduated from Waseda University Senior High School in March 1985. He enrolled in Waseda University and graduated from its School of Law in 1992. == Career == === Tecmo (1992-2008) === Itagaki joined Tecmo in 1992 as a graphics programmer, and initially worked on the Super Famicom version of the American football video game, Tecmo Super Bowl. He was mentored by Yoshiaki Inose (of Solomon's Key, Bomb Jack, Rygar and original Ninja Gaiden fame) and Akihiko Shimoji (Tecmo Bowl) in his early years at Tecmo, and learned from them to include fun as a necessary component in his projects. His career breakthrough came in 1996 with his first Dead or Alive game, a game based on Sega Model 2 hardware (Virtua Fighter) created in response to a request from Tecmo management. The release of Dead or Alive 2 greatly increased the series popularity, as well as Itagaki's. He had sought to create fighting games with details he felt were lacking in other games. However, at D.I.C.E. 2012, Itagaki said Tecmo tricked him into releasing the game before he felt it was fully completed which greatly upset him. Starting with Dead or Alive 3, Itagaki would release a series of successful games exclusively for Xbox. Itagaki's rise through the company had been steady since then. He was appointed the head of the third creative department in April 2001. and assumed the leadership of Team Ninja in July of the same year. In the Dead or Alive Xtreme Beach Volleyball series, Itagaki brought together the girls of Dead or Alive onto an island. The player is to foster good relationship between the girls to create a harmonious winning beach volleyball duo. In the second iteration of the series, the focus is shifted by expanding the number of activities the player can have the girls take part in. He explained the core of the game as a paradise where the player can watch the girls they 'love' enjoy simple activities. For Dead or Alive 4, he pushed back the release of the game in order to polish the game based on feedback of top Japanese Dead or Alive players recruited to playtest the game. He decided to exclude guns from the moveset of the Spartan named Nicole in Dead or Alive 4. The Butt Battle, and Tug-of-War of Dead or Alive Xtreme 2 were heavily panned on the basis of minigame design. Itagaki defended those games as nostalgia comedic pieces, meant to make the player remember the celebrity games played on Japanese television. With Dead or Alive Xtreme 2, he chose to patch an easy-cash exploit rather than leaving it alone and ruminating over the consequences. Ninja Gaiden (2004) was Itagaki's effort to develop a game centered on violent gameplay with super ninja Ryu Hayabusa as the protagonist. Capitalizing on the brand name of the earlier NES series, Itagaki developed a critically acclaimed action-adventure game for the Xbox. While working on Ninja Gaiden, he wanted to produce the "best and the ultimate action game" on the Xbox before moving on to the Xbox 360, which led to the production of the additional downloadable content Ninja Gaiden Black. He continued work on it to release an enhanced version, Ninja Gaiden Black. Tecmo appointed him as an executive officer in June 2004 and later assumed the position of general manager of the high-end production department in February 2006. In March 2008, he released Ninja Gaiden: Dragon Sword for the Nintendo DS. The move to a portable console was partly due to a promise made to his daughter. Itagaki claimed to be one of the very few in the Japanese video game industry to establish communications with the Western world. He suggested other Japanese developers should do like-wise and be aware of the gaming tastes outside Japan, so as to be able to reverse the Japanese gaming industry slump of the mid 2000s. He objected to the suggestion of Kasumi in the Ninja Gaiden universe, saying her 'soft' nature conflicts with the 'hard-edged' nature of the game, whereas Ayane perfectly fits in. === Lawsuit === In 2006, a female former Tecmo employee filed a sexual harassment suit against Itagaki. She claimed that Itagaki had made several unwanted sexual advances on her since 2003. While Itagaki admitted to kissing her, he claimed that whatever had gone between them had been consensual. Tecmo's ensuing investigation reached the conclusion that "the allegations in question were a result of the former employee's desire to vent frustration over her own personal affair, and not indicative of sexual harassment." Tecmo also demoted Itagaki and the accuser for their mingling of "personal affairs with their corporate responsibilities". In June 2007, a Tokyo district court found Itagaki innocent of the charges. === Departure from Tecmo and later projects === On June 2, 2008, just before the release of Ninja Gaiden II, Itagaki released a statement in which he announced that he was resigning from Tecmo and was suing the company for 148 million yen ($1.4 million) for withholding a bonus promised for his previous works. He was also suing Tecmo's president Yoshimi Yasuda for damages based on "unreasonable and disingenuous statements" made in front of Itagaki's colleagues. In a 2010 interview with 1up.com, Itagaki revealed that he was working on a project with former members of Team Ninja under a new studio, Valhalla Game Studios. The title in question, Devil's Third, was revealed shortly before E3 2010. In 2017, Itagaki announced he had become a special advisor to video game company Metal Soft. In January 2021, Itagaki announced that he had established a new game studio, Itagaki Games. At its inception, Itagaki said Itagaki Games would release its first game for PlayStation 5, Xbox Series, and PC. In early October 2024, the studio was dissolved, leading to initial reports that he had left the games industry. However, it was later discovered that he had renamed his production company to Itagaki Games Co., Ltd. in September 2024, which continued to operate. == Works == == Design approach == === Game design philosophy === Itagaki believed a good game should be an integrated product of good graphics, interactivity, and playability. He also placed a high priority on ensuring his games are interactive with the player's actions and respond quickly to the player's inputs. It is this opinion which led to his derogatory statements on Heavenly Sword. He found the payoff for the game's button-prompting sequences to be less fulfilling than that of Genji: Dawn of the Samurai, whose Kamui sequences he called dumb, but entertaining. Likewise, he cited Metal Gear Solid 2: Sons of Liberty and Final Fantasy X as games lacking the interactivity appealing to him. Itagaki professed a liking for simplicity of inputs, he stated too many inputs would result in the loss of the gaming experience. As such, he respected Sega-AM2 for their work on Virtua Fighter 4, while maintaining his claim that Dead or Alive 3 is still a better game. Likewise, he deplored implementing scenarios to show off technology just for the sake of it, sarcastically asking what is the point of cutting down "thousand heads of cabbages on screen." In his integration mindset, everything (graphics, controllers, interactiveness, responsiveness, etc.) has its place, even CG pre-rendered cutscenes which he said can deliver a better cinematic experience of some scenes than doing them in real-time. === Opinions on hardware === As a game developer, Itagaki defined his philosophy as being able to extract the strengths of a game machine, and integrate them together to develop games to a level no one else can reach. He defined a game developer's satisfaction with a game machine as dependent upon these criteria. With this philosophy, he continually expressed happiness in developing on the Xbox 360, proclaiming it to be more 'software friendly' than the PlayStation 3 and viewing it as the most powerful console on the market at the time. Furthermore, he admired Nintendo's dedication to innovation with the Wii, which he held in high regard for the "spirit of gaming." Itagaki also spoke of his philosophy for handheld video game consoles, which focused on responsiveness and physical interaction instead of raw hardware power. As such, Itagaki refused to make a game for the PlayStation Portable (PSP), stating it went against the design philosophy of handheld devices. He believed that a game created based on the specifications of the PSP would be more suited for a home console. === Pet projects === Itagaki classified his projects into core projects (for business and technical excellence purposes), and those purely for self-fulfillment. The Dead or Alive Xtreme Beach Volleyball series and Dead or Alive: Code Chronos fall into the latter. According to Itagaki, the Volleyball games are just meant for simple fun, and to fulfill a 'love' for the female characters, letting the player nurture and watch the girls partaking in simple joys. While he admitted to there being sexual content in the game, Itagaki refused to create scenarios which he felt were vulgar for his 'daughters', a term he used to refer to his female characters. Code Chronos falls into the same category of development, developed as Itagaki's hobby for style. === Frank personality === Itagaki valued frank and "to the point" attitudes, believing anything else would allow "quibbles and sectionalists" to come in and derail the train of thought. His frank attitude was also in line with his admitted aggression. This related to his desire for challenges, producing games like Ninja Gaiden which are acknowledged as 'hard' by the gaming industry, and to push himself to produce games which can contend as the best games of the genre. He openly claimed to be the sole creative force behind his projects, as well as being able to convey his plan clearly for the team to understand. He bemoaned that the Japanese are starting to forget the basic concepts, closing off their minds to outside criticisms. Itagaki consistently gave harsh opinions on Namco's Tekken games, mainly due to his grudge against the company for its insulting radio commercial on his Dead or Alive game. He stated he never forgot an insult to his family, and would retaliate with "nuclear missiles more than 100 times for that". This along with what he viewed as Tekken's stagnation in the fighting game genre (starting from Tekken 4), led him to condemn the Tekken series, placing it as his top five hated games, in spite of him stating Tekken, Tekken 2, and Tekken 3 were good games which his family enjoyed. In 2025, series director Katsuhiro Harada revealed that Itagaki had apologised privately to Namco Bandai in 2008, saying he had respected Tekken and its staff, and that his aggressive language was part of a strategy to draw media attention, especially from Western gaming outlets. == Personal life and death == Itagaki was married and had a daughter, whom he has mentioned as one of the primary influences on his projects and a constant gaming partner in games like the Halo series. Itagaki had in his office a set of katana Japanese swords his father made for him, which he tended to take out to show to his visitors. As he wished to stop people from reading his expressions during gambling-type games, he was always seen wearing sunglasses, a habit that became his trademark in the video game community. On October 16, 2025, Itagaki's family posted news of his death through a pre-written message on his Facebook account. He was 58. Team Ninja acknowledged his death and offered condolences on social media, while industry veterans such as Tekken producer Katsuhiro Harada and Super Smash Bros. director Masahiro Sakurai produced separate tributes. == References == == External links == Tomonobu Itagaki at IMDb Tomonobu Itagaki on Facebook Tomonobu Itagaki's profile at MobyGames Tomonobu Itagaki's profile at IGN Tomonobu Itagaki's profile at GiantBomb Valhalla Game Studios International Ltd.
