During the 1950s, apart from playing the "jubango", Go Seigen participated in many three-game special matches against the Honinbo title holders and other notable players. His opponents in these matches included many illustrious names, such as Hashimoto Utaro, Sakata Eio, Takagawa Shukaku, and the ex-Honinbo Iwamoto Kaoru. Go Seigen was also matched against Kubouchi Shuchi, a player from the Kansai Ki-in who had a strong individual style. In these matches, Go Seigen demonstrated an equal dominance over his rivals. He had an excellent record against Takagawa, whose main achievement was winning the Honinbo title for nine consecutive years. In the period between 1951 and 1960, Go won 22 of their games, and Takagawa won 13. By 1960, Sakata had emerged as Go Seigen's most serious rival, but the results of their games between 1950 and 1960 told the same kind of story. Go had 14 wins to Sakata's 9 and one "jigo", or draw.
