From Sega Retro
Osamu "Sam" Ohashi (大橋 修) is an executive member of Sega whose first title was Sonic the Hedgehog 3, where he served as an art assistant. Following this, however, he undertook executive roles (first as Planner, then Director, and finally Producer) for the Soccer Club subset of the Let's make!! series produced by Smilebit (formerly Sega AM6) for the Saturn, Dreamcast and PlayStation 2 consoles.
He has since returned to the Sonic scene by serving as Producer for the Mario & Sonic at the Olympic Games series of games (with Sonic Team and Nintendo) and has held the title of Chief Producer since Sonic the Hedgehog 4 Episode I, usually working with Toshihiro Nagoshi of AM2 fame.
