Highly reccommend checking out a Sumo tournament if your in Japan at the right time of year. My partner & i had an awesome time, the sumo bouts were fast and intense. Having our english speaking guide there to explain rules and the current ladder of champions was really helpful and added to the experience. Our guide was clearly a massive sumo fan! We spend 2 wks in Japan and loved every bit of it, sumo was one of our favorite things of all. I will definately attend sumo again next time im in Japan!
