Experience Unique Outdoor Relaxation at Uenohara Riverside Sauna: A New Trend in Yamanashi!

Unwind in Nature: Uenohara Riverside Sauna Experience

If you're looking for a way to relax amidst nature, the Uenohara Riverside Sauna in Yamanashi Prefecture offers an incredible experience that's just a short drive away from Tokyo. Located approximately 80 minutes from the bustling city, this outdoor sauna sanctuary combines the unique activities of tent sauna use with trout fishing, providing a perfect getaway for the spring outdoor season.

The Perfect Gateway to Nature

Many people dream of enjoying a tent sauna session in the great outdoors but hesitate due to fears about long travel times and fatigue. However, Uenohara, as the gateway to Yamanashi, is surprisingly accessible, making it the closest resort area to the city. Situated along the vast Kurokawa River, the Uenohara Riverside Sauna presents an open and breathtaking location that is perfect for day trips, allowing visitors to easily dive into a genuine Yamanashi sauna experience.

Three Unique Features of Uenohara Riverside Sauna

1. Exclusive Fishing Opportunities
One of the biggest draws of the Uenohara Riverside Sauna is the ability to combine your sauna experience with trout fishing, available exclusively to sauna users. Rent a fishing rod, enjoy the sweat-wicking sauna sessions, and then take a break by casting a line into the river. You can even prepare your catch on-site, grilling the fresh trout right by the water. The joy of having a meal sourced from nature, paired with the sauna's heat, offers a culinary experience that's hard to find elsewhere.

2. Extreme Temperature and Natural Refreshment
The tent sauna can heat up to a sweltering 100°C to 120°C, thanks to a wood-burning stove that radiates warmth. You can control the humidity and temperature according to your preference through self-heating techniques. After reaching your heat limit, a refreshing plunge into the nearby river awaits. Summer water temperatures hover around 13°C to 15°C, providing a crisp and invigorating sensation, while winter temperatures dip into single digits. Floating freely in the spacious river under the open sky delivers an overwhelming feeling of liberation that truly promotes deep relaxation.

3. Private Group Experience
Uenohara Riverside Sauna operates on a private group reservation basis. You only need to bring four simple items: clothes that can get wet, a towel, sandals, and a change of clothes. There’s no need for complicated setup or teardown — making it easy even for outdoor novices or groups of women to enjoy a day away in nature.
