Ushinohama Satsuo
(牛之浜撮雄, b.1948) Kansai Ki-in pro, 9 dan in 1977.
Hashiguchi Mika and Muraoka Mika are his pupils.
In the 6th Tengen Challengers' Final played on 23 October 1980, Ushinohama lost a game versus Yamabe Toshiro on time after 51 moves. During the dinner break, Ushinohama had fallen asleep in one of the bedrooms on the 8th floor of the Nihon Ki-in and could not be located to resume the game.
Fairbairn discussed this event twice on L19, both times in 2011: in a dedicated thread ''Goldilocks go'' and in ''Igo Kansai''.
