First appearance: Lesson 16 (manga), Lesson 3 (anime)

Age:  31 

Teaches:  Social Studies and Physics 

Interests:  Handicrafts, Flower Art, Macaroni Collages, his pet hamster

He's kinda of a renaissance type of guy. One of the few teachers that Onizuka has befriended/ hasn't made enemies of.  Very much a minor supporting character.
