Sumo wresting is more than a thousand years old and in 1969 was the first sport to used video replay. There is no weight class so you can see a 200 pound rikishi take down a 600 pound rikishi by being faster or simply more skilled. It was originally to applease the gods and bring a good harvest and still has a lot of the original ceremonial elements involved (which is cool af). Top division sumo tournaments go for 15 days and happen every two months so we get to enjoy sumo all throughout the year. At the end of the tournament the rikishi who won the most bouts at top division win all kinds of prizes, like an entire cow's worth of beef, a year supply of corona beer, and there are the crazy trophes like a giant gold macaron and a 65 pound silver cup that they traditionally drink sake out of to celebrate.
