Godokoro is a title that was given in Japan from the beginning of the Edo period until the Meiji Restoration. In that period it was the highest official standing that could be attained by a go player. Literally it is a metonym, meaning the 'go office'. The title was created by Tokugawa Ieyasu and was given by the Jisha-bugyō. The Godokoro was required to be a Meijin and to be the best player in the land.
