Entry period

Applications accepted March 1–31, 2026 (must arrive by March 31). Selection results published on the website in late April.

Notes

Attendance at the in-person athlete registration and opening ceremony on July 18 is required, making this race effectively inaccessible without being physically present in Japan. No mention of overseas-specific entry support.
