Preliminaries

In the preliminaries, 24 players (18 from Nihon Ki-in, 6 from Kansai Ki-in) earned access to the main tournament. They were joined by three semifinalists of last year's main tournament (Ichiriki Ryo, Nishi Takenobu, Yu Zhengqi) and Seki Kotaro, Kyo Kagen. The fourth semifinalist, Yoda Norimoto, was suspended for 6 months by the Nihon Ki-in.
