Notoro Onsen Tenku no Yu

Notoro Onsen Tenku no Yu is a mountain hot spring facility located in Kagamino Town, Tomata County, in the northern reaches of Okayama Prefecture near the Tottori border. Situated at an elevation of 700 meters, it holds the distinction of being the highest hot spring in Okayama Prefecture. The facility is built in Tominishidani, a mountainous area characterized by forests, valleys, and rural landscapes that showcase different seasonal beauty throughout the year.

The hot spring takes its name from the surrounding natural environment and emphasizes sustainable practices. The facility uses solar energy for heating, making it one of the few environmentally conscious onsen operations in the region. The waters flow naturally from the source without artificial pumping, and the buildings incorporate locally sourced Japanese cypress to create an authentic mountain lodge atmosphere. The establishment represents a modern approach to traditional Japanese bathing culture while respecting the natural mountain setting.

Visitors to Notoro Onsen experience both indoor and outdoor bathing facilities. The main attraction is the spacious open-air bath where guests can soak while taking in panoramic views of the seasonal landscapes. The changing scenery includes spring greenery, summer forests, autumn foliage, and winter snow. On clear nights, the high elevation and minimal light pollution create exceptional stargazing opportunities.

The indoor facility features granite tubs and medicinal waters. The on-site restaurant serves local specialties including dishes prepared with wild vegetables and amago, a local river fish sometimes called Japanese land-locked trout, which is a regional specialty of Kagamino Town.

Access to Notoro Onsen requires private transportation, as the facility is located approximately 40 minutes by car from the Chugoku Expressway Innosho Interchange or about 30 minutes from the Yonago Expressway Kuze Interchange. The facility provides parking for 50 regular vehicles and 4 large buses. General admission costs 700 yen for adults (junior high school students and older) and 320 yen for children (ages 4 through elementary school).
