About this race

The Osaka Half Marathon is a 21.0975 km race run each late January in Osaka, Japan, alongside the elite Osaka International Women's Marathon, whose leaders its runners meet mid-course. Founded in 2006, it starts by Osaka Castle Park's east side and finishes in Yanmar Stadium Nagai on a flat, JAAF- and World Athletics/AIMS-certified course built for personal bests. Around 6,000 run it in cold, dry midwinter under a strict 2-hour-5-minute cutoff. The 2027 edition is on January 31.
