Yamashita made it the very hard way. He seemed to have the match all wrapped up when he swept to a 3-0 lead, but Hane Naoki made an extraordinary comeback, taking the next three games to set up a climactic showdown.
Hane Noki could not give him revenge for his failed defense of Honinbo title against Yamashita last year when he lost 4-1.
