“Kimarite” (決まり手) is the Japanese term for the winning technique used to decide each sumo bout. Those studying Japanese will be able to recognize the kanji as deriving from the verb kimaru (決まる), to decide, and te (手), meaning hand. I wonder if this is the term used for a winning hand in poker?
There are 82 of these winning techniques recognized in professional sumo. Of those, seven are known as the kihonwaza, or fundamental techniques which account for the vast majority of sumo bouts. In the most recent tournament, Aki 2018, more than 70% of wins came from these seven: tsukidashi, tsukiotoshi, oshidashi, oshitaoshi, yorikiri, yoritaoshi, and abisetaoshi. Abisetaoshi occurs much less frequently than the others but those main six comprise the go-to toolkits for many rikishi. In fact, oshidashi and yorikiri accounted for more than half of Aki bouts, and nearly half when just looking at makuuchi bouts.
During the upcoming tournament, Tachiai will be tracking and reporting on the kimarite used each day. My favorite group of kimarite are the throws, or nagete. Several of those are relatively frequent, like uwatenage and shitatenage. The spectacular ipponzeoi, though, was used only once last tournament, in a Day 1 Jonidan bout between Tatsunoumi and Wakasatake. It was a great way to start the tournament for Wakasatake. He ended up finishing with a 4-3 record while it sent the “victim”, Tatsunoumi, on a three-bout losing skid, ending 2-5.
