Tokuhiko Uwabo (上保 徳彦), born April 26, 1960, is one of the older sound members in Sega's history, more commonly known by his alias, Bo. He mainly dealt with sound porting during the Master System era and shifted to a more advisory role for the Mega Drive era. He also composed the music for the first two Phantasy Star titles.
Though Uwabo's last known game with Sega was Sonic 3 & Knuckles in 1994, he has stayed in touch with the company following its release. In 1995, he transferred to Sega of Europe's development team, residing in Richmond, London, England. In 1997, he returned to Sega of Japan, but quit sometime afterward. He then spent the next 10 years between some number of investment companies, including a new role as a Venture Capitalist in Tokyo looking over different investment portfolios in Asia.
In June 2007 he joined Winlight Co., Ltd., a mobile gaming company, and worked there as a director. After Winlight was bought in 2012 by Singapore based Pole To Win Asia Pte. Ltd., Uwabo was promoted to Managing Director. Despite having left Sega (which was unofficially publicized as early as April 2006 via liner notes), he has provided commentary for recent Wave Master soundtrack releases of his compositions.
Uwabo currently lives and works in Singapore.
