Hiwasa Umigame Triathlon
ひわさうみがめトライアスロン
This annual triathlon in Tokushima combines a coastal swim at a sea turtle nesting site with cycling and running through scenic landscapes.

No race in 2027: the organizers will not hold the triathlon in July 2027, because the Ohama area hosts the World Masters Games on 22 and 23 May 2027. The next edition hasn't been announced yet.
The Hiwasa Umigame Triathlon is an annual race in Minami Town, Tokushima Prefecture. Its 27th edition was held on 19 July 2026.
The triathlon course consists of a 1.5-kilometer swim, a 40-kilometer bike ride, and a 10-kilometer run. The swim takes place at Ohama Beach, a scenic coastal area known as a nesting site for sea turtles. The cycling segment follows the Sunline route, offering views that extend toward Cape Muroto. The running portion continues along the clear waters of the Hiwasa River. The course is designed to showcase the natural landscapes of sea, mountains, and river that characterise Minami Town.
Participants may compete individually in the age-group division or enter as part of a relay team. In 2026 the entry fees were 23,000 yen for individual competitors and 36,000 yen for relay teams.
The triathlon is accompanied by related events highlighting local culture. On 18 July 2026, the day before the race, the 63rd Hiwasa Umigame Festival took place, with local food stalls, evening market booths, Awa Odori dance performances and a fireworks display.
