The Tokyo Yamathon is an annual endurance and fundraising adventure where teams of 2 to 4 take on the challenge of walking or running around Tokyo’s renowned JR Yamanote train line. Will your team conquer all 30 stations in under 12 hours? Or will you opt for the Half Yamathon, visiting 15 stations in approximately 8 hours?

• Strider Registration Period: August 14, 2026 (for team sign-ups)
