The Japan Triathlon Union organized an Aquathlon in Tokyo bay on 31 August.

Fuji Television, one of the major television network company in Japan, collaborated on this event, which was held in the center of Tokyo.

Ryosuke Yamamoto, an Olympic swimmer from the Beijing Olympic Games, joined it and athletes enjoyed good race conditions and weather.

If Tokyo is selected to organize the Olympic and Paralympic Games in 2020, this area will be used for Triathlon and Open water swimming.
