After the league, there was a three-way tie for first, which was resolved by a round robin won by Sakata.
There was a single elimination playoff for fourth place (to retain a place in the league). Fujisawa received a first round by, and won his game (against Takagawa). Nevertheless, he did not participate in the 7th title. On the other hand, Takagawa came back through the preliminary round to regain his place in the league, which he won and went on to defeat Hashimoto Utaro in the title match to begin his remarkable run of nine straight Honinbo titles (only recently surpassed by Cho Chikun).
In the first stage, 32 unseeded 5, 6 and 7 dans were sorted into five knockout groups.
The winners of these groups (Sakata Eio 7 dan, Mitsuhara Itaro 7 dan, Miyashita Shuyo 7 dan, Shinohara Masami 6 dan and Magari Reiki 5 dan) advanced to the second stage along with the five players who had 3-3 scores in the 5th Honinbo league (Fujisawa Kuranosuke 9 dan, Hasegawa Akira 7 dan, Hayashi Yutaro 7 dan, Kitani Minoru 7 dan, Takagawa Kaku 7 dan).
In the second stage, players were eliminated after two losses.
