The Aoshima Oni no Sentakaban Aquathlon 2026 is an aquathlon event held at Aoshima Beach in Miyazaki City, Miyazaki Prefecture. The venue offers a breathtaking view of the 'Oni no Sentakaban' (Devil's Washboard), a designated National Natural Monument. In addition to traditional swimming and running disciplines, the 2026 edition introduces a new 'Sunset Ekiden' category. With 8 categories available, the event caters to a wide range of participants, from beginners and veterans to children. An after-party is also scheduled following the competition to foster community among participants.
The most striking feature of this event is the competition set against the iconic landscape of the 'Oni no Sentakaban' in Miyazaki. In addition to the standard aquathlon courses along the palm-lined coastline, the 'Sunset Ekiden' offers a unique way to experience the evening scenery. After the race, participants can enjoy an after-party, the fee for which is already included in the competition entry fee. This provides a great opportunity for athletes to socialize and build community.
