This quirky race held since 1956 sees individuals in barrels paddle down the Matsukawa River in Ito City on the Izu Peninsula.
What happens?
Participants, eager to win, set sail in large tubs armed with nothing but their dignity and two hand paddles. Getting wet is expected as they speed down the 400-meter course. To ensure the level is nice and high, extra water from the local dam is released.
Teams from around the world enter to compete in this competition. (In Italy, they also sometimes race in washtubs.) You must pre-register to enter the race and can do so on the official site (in Japanese). Spectators can watch from the sidelines.

How to get there
The starting point at Ideyu Bridge is around a 10-minute walk from Itō Station. To get to Itō from Tokyo Station, take the Odoriko train for around 1 hour and 30 minutes. An alternative and cheaper option is to get the Shinkansen to Atami Station and then change to the Itō Line.
