Tengen competition (天元戦)
The Tengen competition is a Go tournament run by the Japanese Nihon-Kiin and Kansai-Kiin. The Tengen is the 5th of the 7 big titles in Japanese Go.
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 tournament was formed from a merger between the Nihon Ki-in and Kansai Ki-in championships. The former ran from 1954 to 1975.
