第5回 浅虫温泉マラソン 2026

The Asamushi Onsen Marathon is a road race in Aomori City, in the Hokkaido and Tohoku region of northern Japan. This fifth edition is centered on Asamushi Onsen, a hot-spring area on the edge of Aomori, with runners using a special course around Hotaru Lake. The course detail is the main draw here: instead of a generic city route, it sends runners around the lake in the onsen district. The available information points to a local race rather than a huge international marathon, with registration handled through the official event page and entries open ahead of race day.
