Taiho stable

According to Japanese Wikipedia, Taiho stable was renamed Otake stable on 1 January 2004, when the 16th Otake succeeded, so it no longer exists under the name Taiho stable. It was founded in December 1971 by Taiho Koki, who reached yokozuna, the highest rank in sumo, branching off from Nishonoseki stable. The stable belonged to the Nishonoseki ichimon.

According to Japanese Wikipedia, Taiho spent 25 million yen (at the time) to prepare a new practice hall when he founded the stable.

According to Japanese Wikipedia, the practice-hall plaque bore the character 忍 (endurance) that Taiho added to his signature during his active career.
