Mitokorozeme (三所攻め; "triple attack force out") is a triple attack. Wrapping one leg around the opponent's (inside leg trip), grabbing the other leg behind the thigh, and thrusting the head into the opponent's chest, the attacker pushes him up and off the surface, then throwing him down on his back. This is a very rare technique, first used in the modern era by Mainoumi Shūhei, who used it two or three times in the early 1990s (officially twice, on a third occasion his win was judged by most observers to be a mitokorozeme, but was officially judged an uchigake). Ishiura successfully used it against Nishikigi on Day 8 of the November 2019 tournament, for the first time in makuuchi since Mainoumi in 1993.
