About the Osaka Marathon

Osaka Marathon is one of Japan's major urban marathons, with a mass field, elite racing, and charity participation. It sits in the late-winter calendar, giving runners cool conditions on a big-city course.

Course

Recent editions start near the Osaka Prefectural Government building and finish inside Osaka Castle Park. The route is a certified 42.195 km city course, but runners should recheck the event guide because final routing can change between editions.
