一色 識央 (also Satoo) 
Retired Nihon Ki-in professional
Isshiki had a short career. He qualified as a professional on 1997-04-01 and was promoted to 2p in the same year, on 1997-07-09.  However, he was not promoted again, and retired from play in 2000. 
 He's actually called Satoo everywhere else. Perhaps that convention should've been followed here. Never sure whether to keep doubled Os.
