Tengen competition (天元戦)
It has the same format as the other tournaments. There is a preliminary tournament, which is single knockout, where the winner faces the holder in a best-of-five match.
Before the 6th Tengen, the format was different. Instead of the title holder waiting for a challenger, it would be the two Go players left from the single knockout tournament who then played a best-of-five match to determine the holder.
- The first player to win the competition twice was Kato Masao, in the 7th Tengen. However, in 1993, Rin Kaiho reached a record 5 wins.
