~Experience “Run Japan” －One Race, A Thousand Memories~
Shonan is the beautiful coastline area an hour south of Tokyo by train. The marathon starts and finishes in the historic aristocratic resort town of Oiso and runs along world-class beaches with spectacular views of Mt. Fuji. Some of Japan’s most popular sightseeing spots like Kamakura and the hot spring town of Hakone are just minutes away.
The Shonan International Marathon is the world’s first major marathon to achieve zero waste from paper cups and plastic bottles at drink stations along the course. At our 2025 race we reduced the event’s waste by 76%, an initiative that got almost unanimous support from runners who loved both the experience of running on a clean course with no trash and knowing that they were helping to reduce the event’s environmental footprint.
Our goal is to make the marathon a more environmentally-friendly sport. Runners are asked to carry their own bottles or cups and to refill them at any of the 200 aid stations along the course, an innovative approach that eliminates the massive waste that is the norm at other races.
