Mechanics
The wrestler turns his back to the opponent, grips his arm with both hands and throws him over his own back. Known from judo, in sumo this throw is extremely risky — the thrower must keep his own knee off the dohyō, or he loses. Famous executions include Kaiō's win over yokozuna Musashimaru in 2000 and Hōshōryū's win in 2021.
