Videogame creator. Yoot's most popular work is probably Seaman for the Sega Dreamcast. His games are usually published by Sega. He is quite a character, and is said to be friends with Shigeru Miyamoto. His other noteable game is Yoot Tower.
Side notes: It was Yoot's face that was used as the face of a mature Seaman.
He wanted to make Seaman for the PC so that the game could search any avalible network and find personal data to suprise you with.
The Japanese version of Seaman is said to be far less talkitive than his western counterpart.
