His alias' namesake is an emphasized version of the company's first syllable, Kou, and Shibusawa Eiichi. He's also taken credit as Eiji Fukuzawa, first part a derivative of Koei's "ei" and the second name being a homage to Fukuzawa Yukichi.
He is also going to lead the production of the PS3 version of Hisao Kurosawa's film, tentatively titled "Oni" and later "Ni-Oh". Both the film and game were going to be co-produced at the same time. The film was projected to be out in 2006 but the current status for both projects remain unknown.
He states that he first became interested in the Romance of the Three Kingdoms from various comics based on it. He then read the novel, which eventually lead to his hobby of exploring global history. To replicate the same experience in others, he aims to make all his projects "entertain and educate" players. His goal for creating video games is also the company's motto.
While famous for his video game contributions, he is making a recent debut to the film industry as the supervisor in charge of the Japanese dubbed version of The Last Airbender (known as Airbender in Japan). Though it is his first time dealing with Japanese voice overs, Shibusawa remarks that he has confidence since he can use his experience with cinema in video games to help him. He hopes to create an emotional and action filled impact with his interpretation of the movie script.
When asked about which Koei product he would like to adapt to film, Shibusawa expressed a possible interest in making a live-film adaption of the Dynasty Warriors series.
