About the Event

Immerse yourself in the stunning beauty of Shiga Highlands National Park, one of Japan's premier national parks and a UNESCO Eco-Park. This breathtaking landscape offers runners an unparalleled 100km trail running experience through its cool summer climate, making it ideal for long-distance races.
The race route winds through pristine wilderness where participants can witness dramatic vistas rarely seen by outsiders. From dense forests to open meadows filled with wildflowers and towering peaks, the scenery is nothing short of spectacular. The challenging terrain includes rugged trails that test endurance while rewarding runners with panoramic views at every turn.
In addition to the main 100km event, there are also shorter options: a 40km race and an 18km course for those looking for a more manageable distance yet still wanting to take in the natural splendor of Shiga Highlands. All participants contribute to maintaining the park’s trails through their entry fees.
Registration costs:
- Main Event (100km): ¥28,000
- Supporting Race (40km): ¥9,900
- Shorter Course (18km): ¥7,500
This race is more than a competition; it's an opportunity to explore one of Japan’s most pristine and awe-inspiring natural settings.
