With the concept of "connecting marathons to the future," the event proudly positions itself as one of the most eco-friendly marathons in the world, reflecting Japan's leadership in environmental sustainability.

Just One Hour from Tokyo — Excellent Tourism Potential

Nearby attractions include famous spots such as Kamakura (with its Great Buddha), Enoshima Island, and Hakone's hot springs. After the race, you can relax in a hot spring for recovery or enjoy cultural experiences. The historic resort town of Oiso also offers beautiful beaches and delicious local gourmet food.
