Event Detail
The 24th Kashiwazaki Marathon takes place on Sunday, 25 October 2026, in Kashiwazaki, Niigata Prefecture, on Japan's Sea of Japan coast. Despite its name, the 2026 programme does not include a full marathon: runners can enter an officially certified half marathon, a 10 km race or a 3 km event. Its Japan Association of Athletics Federations (JAAF)-certified road course starts and finishes at Kashiwazaki City Athletics Stadium, making it attractive to road runners who value recognised course standards.
Courses, guest athletes and special links
The race offers 21.0975 km and 10 km divisions for both JAAF-registered athletes and general participants. The 3 km division also welcomes eligible school-age runners and family pairs. Organisers cap total participation at 1,100, allocated on a first-come, first-served basis.
The city has announced guest appearances by long-distance runner Yuma Hattori, associated with Toyota's athletics team, and Kinari Ikeda of Bourbon. The official RUNNET edition page also identifies this event as a RUN as ONE - Tokyo Marathon partner race: three participants are to be selected by ballot for Tokyo Marathon entry rights, with associated travel expenses borne by the selected runners. Check the organiser's rules for any eligibility limitations rather than assuming all divisions qualify.
