Shimonoseki Kaikyo Marathon
The Shimonoseki Kaikyo Marathon draws approximately 9,000 finishers each November on a harbor road in Shimonoseki, Japan. The narrow strait setting gives the race a dramatic maritime character from start to finish. The course passes Kanmon Strait waterfronts, fishing-port districts, and repeated sea views toward Kitakyushu. Rolling terrain with moderate climbs shapes the middle miles.
Next race: Sunday, 1 November 2026
