Seiji Ogata (緒方精次, Ogata Seiji) is a Professional 9 Dan and a student of Koyo Toya, who later obtained the titles Judan and Gosei after Koyo Toya retire from Professional Go


Ogata anime
In the anime

Ogata is a tall man with dirty blond hair. He wears glasses over his sharp brown eyes and is usually dressed in a white suit when playing. Sometimes he is seen smoking cigarettes at home. Altogether, he is in the very image of modern Japan - living hyper-modern yet playing a strategy game thousands of years old.


A fiercely focused man, Seiji has a tendency towards obsessing over things, especially whenever they do not make sense to him or he does not have all the facts, much to the distress of Shindou. He likes dissecting puzzles and often overthinks, which once cost him the Honinbo title.

Having been born in between the "great waves" of the Japanese Go world, Ogata is somewhat title-crazy, seeking to welcome the younger generation as title-holder. He thus has a heavy rivalry/war going with Kuwabara Honinbô about the latter's title, who refuses to give it up.


Not much is known of Ogata Seiji's history, but it should be noted that he entered the Go World in a time of relative calm, where people like Koyo Toya and Kuwabara dominated the field. Eventually, he became the student of Touya.
