May Grand Sumo Tournament (2013)

Japan's sumo wrestlers return to the Ryogoku Kokugikan for their annual May tournament this month, the highlight of which is likely to be seeing whether hapless ozeki Kotooshu manages to avoid demotion after a disastrous showing in March. Hakuho and Harumafuji are once again duking it out at the top yokozuna rank, while handsome Shimane-born wrestler Okinoumi Ayumi makes his debut as a komusubi, the fourth highest rank. There are cheap ¥2,100 tickets available on the door each day, though get there early if you're hoping to score one – especially at the weekend. Note that while the tournament starts at 9am each morning, the top ranked wrestlers don't come out until around 4pm.
