Sumo (相撲), where two large mounds of flesh rumble in a fashion that closely resembles Western-style wrestling, is considered a modern Japanese martial art.
Look up the word “martial” in an English dictionary, and you’ll find this:
Not sure how you’d use sumo in battle, but … who knows? Maybe in hand-to-hand combat with a string bean militant you can bounce him with your rotund gut?
In any event, here are three 30-stone-weighing, fun-loving sumo wrestlers — Kento Amakaze, Tatsuaki Kaiho and Kanata Takatenshu — sprinting each other on a running track while on a break from practice on a sunny day in their native Japan.
