About the Event

Set against the backdrop of one of Japan's southernmost islands, Hachijō-jima offers runners an unforgettable experience just 55 minutes by plane from Haneda Airport and approximately two hours south of bustling Tokyo. Known for its pristine natural beauty and crystal-clear waters with a transparency boasting up to 50 meters, this island paradise is the perfect setting for a unique running adventure.
The race route takes participants through lush green landscapes and along picturesque coastal paths where they can admire the legendary "Hachijō Blue," a term coined for the stunning turquoise hues of the ocean that surround the island. As runners traverse these scenic routes, they will have ample opportunities to appreciate Hachijō-jima's rich biodiversity and serene atmosphere.
This event is not just about reaching the finish line; it’s an invitation to explore one of Japan’s hidden gems while immersing oneself in its tranquil environment and breathtaking scenery. Whether you are a seasoned runner or simply looking for a memorable day out, this race promises to deliver a unique blend of physical challenge and natural beauty.
Runners will enjoy the island's tranquility and feel rejuvenated by the fresh sea air as they make their way through one of Japan’s most picturesque running routes. The event is designed to showcase Hachijō-jima’s charm beyond its stunning beaches, offering participants an intimate look at a lesser-known part of Japan.
Join us on October 4, 2026, for this extraordinary journey and experience the enchanting beauty that awaits you in Hachijō-jima.
