Osaka Yodo-River Citizens Marathon 2026

The Osaka Yodo-River Citizens Marathon offers both marathon and half marathon distances in Osaka, following the Yodo River. It was established in 1997 by local residents for local residents, emphasizing participation and completion over competitive placement. This event was notable as Japan's first marathon organized solely by citizens and the first held exclusively on a riverbed. The course largely follows the river with out-and-back segments and minimal elevation changes, favoring a consistent pace. The terrain includes road, sidewalk, gravel, pebbles, and dirt. The start is in Asahi Ward, with convenient public transport access from Osaka and Kyoto. While the field is substantial, it has set limits for both distances. The event also includes medical runners, post-race seminars, and sells custom bib holders.
