The rules are simple; if any part of your body other than the bottom of your foot, you lose; you step outside of the ring, you lose. This has lead to a wide variety of strategies and tactics, from forcefully pushing someone out, throwing them to the ground, pushing, or even using the harite or palm strike. I've always been enthralled by Sumo; namely as its one of the few wrestling sports to allow for open hand striking. Combine the open weight class dynamic of sumo, and it can lead to some pretty amazing matches. One of my personal favorites is this man, Kyokudozan. For the people with the advanced strikers eye, what is Kyokudozan doing that is so effective? It seems like there's a lot of shovel hooks (palms?) coming up at angles, but I've always been more of a grappler than a striker, so the reason for his success eludes me. Not that I'd do this without warning my sumo training partners first, I'd like to add this skill to my skillset. Thanks for any guidance y'all can give.
