About the Event

Experience the beauty and depth of Japan's natural wonders at the Tazawa Lake Blue Marathon, an unforgettable race that takes runners through stunning landscapes around picturesque Tazawa Lake. This event offers participants three distance options: a full marathon (42.195km), a half-marathon (20km), and a 10-kilometer course.
The marathon route winds along the serene shores of Tazawa Lake, known for its crystal-clear blue waters that reflect the surrounding mountain scenery perfectly. Runners will enjoy breathtaking views as they traverse this picturesque area, making it not just a physical challenge but also an immersive journey through nature's splendor.
For those who prefer shorter distances, both the half-marathon and 10km runs offer equally scenic routes with their own unique highlights. The atmosphere is lively yet serene, providing runners of all levels a memorable experience amidst Japan’s natural beauty.
Entry fees vary depending on the distance:
- Full Marathon (42.195km): ¥10,000
- Half-Marathon (20km): ¥8,000
- 10-Kilometer Run: ¥6,000
For those looking to share the experience with a partner or friend, there is also a special tandem entry option available for both full and half-marathons at a reduced rate of ¥5,000 per team.
Please note that participants who enter on the day before the race will incur an additional fee of ¥1,000 across all categories. Early registration is highly recommended to secure your spot in this scenic event.
Join us and immerse yourself in the unparalleled beauty of Tazawa Lake while testing your limits against a backdrop of breathtaking natural scenery.
