Kamakura Jubango
The Kamakura jubango (ten-game match) was a historically significant go match played in Japan in 1939, 1940 and 1941. It pitted Kitani Minoru and Go Seigen, close rivals for a decade and friends at a personal level, and both ranked 7 dan, against each other.
Go Seigen emerged victorious by a 6-4 margin. This match marked the beginning of the period of his dominance as the top player, which continued until the First Meijin Tournament in 1962.
