Ogata Seiji

Japanese name:

緒方 精次

A Go professional who recognizes Hikaru's talent when he comments on a go move during a children's tournament that even professional Go players would take some time to see (although this is Sai's insight - Hikaru had not yet attained much skill by this time). He is also a student of Koyo Toya and soon takes the Judan and Gosei titles when Koyo Toya retires. He keeps tropical fish and smokes heavily.
