Mr. Yamamoto is the father of Julie Yamamoto.
Mr. Yamamoto is a middle-aged Japanese-American man who has graying hair and a mustache. He wears a blue button-down shirt.
Mr. Yamamoto doesn't seem to be very trusting of Ben, bordering on a distaste for the young man. While this may be out of concern for the safety of his daughter and justified by many of Ben's actions, he apparently does approve of Ben enough to allow his daughter to allow them to continue seeing him. He does, however, set a curfew for Julie, and seems to be rather unyielding about it, much like Ben's own parents.
Mr. Yamamoto appears in the episode The Perfect Girlfriend, in a scene where Ben arrives at the Yamamoto home to ask if Julie is there. He informs Ben that she isn't, and if anything Ben should know where she is more than he would.
