He was a member of the Tomozuna stable, and he was a tsukebito or personal attendant to ōzeki Kaiō for a number of years, as well as a frequent training partner of Sentoryū.
He initially fought under the shikona of Tanaka, before changing to Kaito and then Kaidō (the character "Kai" being a common one in his stable or heya).
Kaidō served as Kaiō's tsukebito or personal assistant when he was in the lower ranks and credited his senior stablemate for encouraging him when he was struggling with injuries.
His danpatsu-shiki or official retirement ceremony was held in the Shinagawa Prince hotel in Takanawa, Tokyo on October 15, 2006.
