The 4th Kisei was the 4th edition of the Kisei tournament. Since Fujisawa Hideyuki won the previous year, he is given an automatic place in the final. Eight players battled in a knockout tournament to decide the final 2. Those two would then play each other in a best-of-3 match to decide who would face Fujisawa. Rin Kaiho became the challenger after beating Hashimoto Shoji 2 games to 1, but would lose 4 games to 1 against Fujisawa.
