Osaka Marathon
Osaka, Japan · Thursday 25 February 2027
The Osaka Marathon 2024 takes place on February 25th as a full 42.2-kilometer road race through Japan with minimal elevation change, making it a genuinely flat to gently rolling course that rarely climbs above 21 meters. The surface is trail-based rather than typical road pavement, which means you'll want to prepare your legs and shoes accordingly for the different impact and footing compared to standard marathon courses. Entry is open to general runners, racing wheelchair competitors, and challenge runners through the official website, where you can also access race results and download your digital certificate after finishing. With the 2025 race already scheduled for February 24th, this event appears to be an annual fixture in the Japanese marathon calendar, so plan ahead if you're considering participation. Check the official Osaka Marathon site for current traffic regulations, preparation details, and any updates on logistics before you arrive.
