In March 1987 he was promoted to komusubi, becoming the first wrestler from Fukui Prefecture to reach a san'yaku rank since the beginning of the Showa era.

He took part in two playoffs for the jūryō championship in May and July 1989, but lost both, to Komafudo and Ryūkōzan, leaving him without a career yūshō in any division.

He was friendly with sumo fan Demon Kogure, and appeared on his radio show All Night Nippon.

He reached the mandatory retirement age for elders of 65 in October 2021, but was re-hired by the Sumo Association as a consultant for a further five years.

On 1 July 2024 the Sumo Association announced that Daitetsu had retired early from his consultant role.
