- This event is one of the first aquathlons for the year in the Kanto area.
- There are many famous onsens (hot springs) in the area.
- From Tokyo it is approx. 2 hours and is doable as a day trip.

The aquathlon takes place at Nagahama Beach Park in Minami Atami, about 2 hours from Tokyo (or approx. 1 hour by bullet train). There are 4 race options: (i) Short aquathlon - 500m swim and 5km run, (ii) Long aquathlon - 1.5km swim and 10km run, (iii) Swim only - 1.5km swim, (iv) Aquathlon relay - 1.5km swim and 10km run

If the weather is good, late May is usually the beginning of summer. In past years, the temperature has generally been approx. 27 degrees, however water temp is usually approx. 20 degrees.

Close to Atami, one of Japan's famous onsen areas, we recommend a day trip to relax and enjoy the hot spings. In summer, it is a popular beach and swimming spot (beach swimming is permitted around mid-July).
