About the event

The 50th Rekikawa Marathon is an exclusive race that welcomes residents, students, and employees of Bunkyō ward, located in the heart of Tokyo. This year's edition takes place on November 29, offering participants several distance options tailored to all ages and skill levels.
For adults eager to challenge themselves over a longer course, there’s the main event: a scenic 9-kilometer route that winds through some of Bunkyō’s most picturesque neighborhoods. The race is designed to showcase the beauty and history of this vibrant district while providing runners with an invigorating experience along its well-maintained streets.
For younger participants aged three years or older, there's also a shorter but equally enjoyable 3-kilometer course that offers a taste of what competitive running feels like. Additionally, children from elementary school to middle school can participate in their own dedicated race for just ¥500.
The event culminates with an exciting relay race option where teams compete against each other over the same beautiful route. This event is perfect for those who want to experience the thrill of team competition and camaraderie while enjoying a more relaxed pace compared to individual races.
Entry fees vary depending on the distance: ¥3,000 for the 9km course, ¥1,500 for the 3km race, and just ¥500 for elementary and middle school runners. For relay teams, the cost is ¥2,500 per team with an additional fee of ¥500 for any accompanying spectators.
This event promises a day filled with excitement, community spirit, and scenic beauty as participants navigate through Bunkyō's historic streets and parks.
