Okamiden started off as a humble fan project. Kuniomi Matsushita and a small group of Okami fans inside of Capcom voluntarily made a Nintendo DS demo. After work was complete, Matsushita brought the pre-prototype to Ace Attorney Investigations producer Motohide Eshiro.
“What in the? Isn’t that white dog, no, white wolf, Okami, running around,” Eshiro exclaimed. Matsushita asked Eshiro if he would produce the game and official developed followed afterward.
