The Osaka Half Marathon starts at Osaka Castle Park and finishes at Yanmar Stadium Nagai, held on the same day as the Osaka International Ladies Marathon. The finish at the stadium is a highlight, and after the half marathon, the ladies marathon runners return to the stadium.

Why attend here

January in Osaka is crisp and quiet, perfect for a 21k that starts among the castle's winter-lit moats and ends at Yanmar Stadium. After you cross the finish line, warm up with a bowl of piping-hot udon in the nearby Shinsekai district, then wander the city's covered arcades where takoyaki stalls and retro arcades hum with local life.
