International Masters Open Water Swim

About the race

The International Masters Open Water Swim at Yumigahama Beach is a quintessential Japanese coastal experience, set against the breathtaking backdrop of the Izu Peninsula in Shizuoka. Known for its pristine white sands and crystal-clear turquoise waters, Yumigahama is widely considered one of Japan’s most beautiful beaches, forming a gentle crescent moon shape that protects swimmers from strong currents, making it an idyllic venue for open water enthusiasts. The event draws a dedicated community of masters swimmers from across Japan and beyond, celebrating a culture of lifelong fitness and competitive camaraderie.

Beyond the race itself, the location is steeped in natural beauty. The beach is bordered by pine forests and offers stunning views toward the volcanic cliffs of the Izu region. Participants often find themselves swimming in water so clear that the seabed remains visible throughout the course, providing a unique connection to the marine environment. The atmosphere is distinctly family-friendly, with the gentle shoreline offering safe conditions for spectators and children to enjoy the coastal vibe. Whether you are a seasoned competitor or a masters athlete looking for a scenic challenge, this annual gathering is a perfect intersection of sport and tourism.
