Let's learn more about sumo!
Featuring a match between Kiho (gold) and Tsushimanada (silver)
Shiko : One of the basic sumo exercises, in which the rikishi (sumo wrestler) raises a leg high in the air to the side, then brings it down with a stamp. It is also performed on the dohyo to drive away bad spirits. Kiho (formerly Kawazoe) demonstrates his balance and flexibility here with his shiko. Learn how to do shiko HERE.
Henka : A sidestep performed at the tachi-ai (the face-off) to avoid an attack and set up a slap-down technique, but this is often regarded as unsportsmanlike. Some say it is a legitimate "outsmarting" move, and provides a necessary balance to direct force, henka meaning 'change; variation'. Though if one does this move too frequently they could gain a reputation for it...
(Also of note, Kiho's hair. Kiho is a younger rikishi and has not yet been able to grow his hair long enough to style into a typical topknot, like Tsushimanada.)
