Hiseikai

The Hiseikai (裨聖會, ひせいかい) was a group of five professional players formed by Karigane Junichi in 1922. Its goal was to play multiple round-robin tournaments under a new playing system with the manifesto of: Time limits to be up to 32 hours per games, 16 hours per player. Players who have not finished playing before expiry of their time allocation lose the game.^[1] It was the first organisation to introduce time limits. It discarded the traditional systems for the So-tagaisen(総互先制, all even-game) system, which is regarded as the birth of the modern playing system. It included even games, regardless of playing strength, time limits and Oteai games. The group consisted of: Karigane Junichi, Onoda Chiyotaro, Segoe Kensaku, Suzuki Tamejiro and Takabe Dohei. It disbanded in 1924 with the founding of the Nihon Kiin.
