第35回葛西臨海公園ナイトハーフマラソン（9月開催） 2026

The Kasai Rinkai Park Night Half Marathon takes place on a Saturday evening in Tokyo’s Kasai Rinkai Park. The half marathon begins at 18:00, followed by the 10km at 18:10. This September event is open to men and women aged 18 and over, with a field limit of 1,500 participants. Registration is required in advance, and separate entry fees apply for the half marathon and 10km. The course follows the area around Shiokaze Plaza in Kasai Rinkai Park, a short walk from Kasai Rinkai Park Station on the JR Keiyo Line. Participants run in the evening to avoid daytime heat. The park provides a relaxed atmosphere post-race, featuring a large Ferris wheel, aquarium, and waterfront areas. Spectators might also see distant fireworks from Tokyo Disneyland.
