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. It was the first organisation to introduce time limits.
It also discarded the traditional handicap systems for the So-tagaisen(総互先制) system (though without komi), which is regarded as the forerunner of the modern playing system (time-limits, all even games with komi and rank promotion on clearly defined conditions).
After completing a quadruple round robin tournament (Karigane won), it disbanded in 1924 with the founding of the Nihon Kiin.
The tournament book has a note on times recorded: "less than 1 minute is rounded off". Therefore it was not a sudden death; consumed times less than 0.5 min (30 seconds) were ignored. The book can be accessed through the Japanese National Diet Library's "Digitized Contents Transmission Service".
