Starting in 1939, Go Seigen began a spectacular series of Jubango matches against other top players of the day. It was through these matches that Go Seigen convincingly demonstrated an overwhelming dominance over his contemporaries. Go Seigen had only two formal disciples — Rin Kaiho, Honorary Tengen and Rui Naiwei, who was the strongest female go player ever and won open Guksu title.
