The 2026 Itabashi City Marathon: A Celebration of Running in Nature

On March 15, 2026, the Itabashi City Marathon was held at the scenic Arakawa riverside, a location that recently received endorsement from both the Japan Athletic Federation and World Athletics. This year's event saw participation from approximately 10,300 runners, set against a backdrop of nature that exemplifies the beauty of running in Japan.

A New Family-Friendly Feature

Introducing a new 1km Family Run segment boosted excitement levels, as more families joined in to enjoy the festivities together. The marathon itself showcased elite athletics, with participants vying for glory from all over Japan.

Among the standout performances, Satoru Suzuki led the men's registered division while Saori Arai triumphed in the women's category. In addition to the marathon, the event hosted several other races: a 5km run, a junior 3km race, a 1km family run, and even a wheelchair 1km event, all of which drew enthusiastic crowds.

Race Details

The marathon began at 9 AM, with runners starting from a designated area in Itabashi-ku and heading towards the Arakawa Bridge in Edogawa-ku in a challenging yet scenic 42.195 km course. Notable guest runners included prominent athletes such as Suguru Osako, a record holder in both the 3000m and 5000m events, and comedic figure Kenji Moriwaki. Pace runner Myako and Olympic champion Reiko Tosa also lent their support to the event, bringing an electrifying atmosphere that encouraged more participants.

Event organizers set up several engaging booths near the course, including a Kid's Zone managed by the Primula Sports Club and various food stalls operated by local merchants, enriching the overall experience for both participants and spectators.
