Ota Yuzo
Ota Yuzo (太田 雄蔵 Ōta Yūzō, 1807-1856) was a professional Go player.
Ota was one of the Tempo Four. He played 23 games out of a sanjubango against Shusaku. Taken from Invincible: Yuzo was Shusaku's top rival and Shusaku played more games with Yuzo than with anyone else. Yuzo's favorite move was the mokuhazushi and he was a very aggressive player. He was also said to be one of the most handsome professional Go players of the time. He did not participate in the Castle games because he would have had to shave his head.
