In the Spring 1938 tournament, though he only had a 2–5 record before pulling out due to injury, he still managed a gold star or kinboshi win over yokozuna Minanogawa, incidentally one of the leaders of the strike back in 1933.

He responded by posting a 13–0 record, including a victory over future yokozuna Haguroyama and winning the championship.

Because he was a lower maegashira, he was not matched against yokozuna Futabayama, who in this same tournament had his record-setting winning streak broken at 69 by Dewaminato's stablemate Akinoumi.

Dewaminato's most common winning techniques were hatakikomi (slap down), sotogake (outer leg trip) and sukuinage (scoop throw).
