The Ibigawa Half Marathon is one of Japanβs most celebrated autumn road races, offering runners an unforgettable combination of spectacular mountain scenery, vibrant fall foliage, and the warm hospitality for which rural Japan is renowned. Held annually in Ibigawa Town, Gifu Prefecture, Japan, the event is the successor to the highly regarded Ibigawa Marathon, which for decades earned a reputation as one of the countryβs finest destination races. Today, the event continues that tradition with the half marathon serving as its flagship distance.
Set against the backdrop of the mountains of western Gifu, the course follows the valleys carved by the Ibi River before climbing into the surrounding countryside. Runners are treated to panoramic views of forested hillsides that burst into brilliant shades of red, orange, and gold during Japanβs autumn foliage season. The combination of crisp November air and colourful scenery creates an atmosphere that is widely regarded as one of the most beautiful racing experiences in the country.
The course itself is known for being both scenic and challenging. Rather than offering a flat, fast profile, the half marathon features a series of rolling hills and sustained climbs that reward disciplined pacing and strong endurance. These elevation changes make the race popular with experienced runners looking for a rewarding challenge while remaining accessible to recreational participants thanks to outstanding on-course support and enthusiastic local spectators.
