Notoro Onsen Tenku no Yu

4.2 (716)Public BathSpaPoint Of InterestEstablishment

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).

The hot springs were great. Both the indoor and outdoor baths are relatively compact, but even a group of 6-7 people could enjoy the hot springs at a comfortable distance. The water is colorless and odorless. It was winter, so we could only enjoy the mountain scenery, but I'm sure it would be even more beautiful in spring, summer, and fall when the trees change color. There's a restaurant next door. It's also a campsite, so it's great to be able to enjoy the hot springs in the evenings or mornings while camping. I'll come again.

The open-air bath with a great view is amazing, and you can soak in it for a long time. The altitude is 700m. Be careful during the heavy snowfall in winter, but the snow scenery is worth seeing.

Alkaline simple hot spring (hypotonic alkaline low-temperature hot spring) pH 9.3, heated at the source The destination is located off the main national highway, over Mt. 1, and up the prefectural road alongside the river. There are signs at the forks, so you won't get lost. I visited the hot spring to cool off during the scorching heat down below. Personally, I had imagined it to be higher (and more difficult), so I was somewhat disappointed and relieved by the access. Unlike down below, a refreshing breeze blows through. The dining area is on the left, and the bathing facilities are on the right. The water temperature was generally lukewarm both inside and outside, and there were some chemicals present. The breeze in the outdoor bath is pleasant, but the sun was intense that day, so I left early and focused on the indoor bath. The water is soft and pleasant. While the location makes it somewhat difficult to access, I think it's a nice, secluded facility. Access by motorcycle was easy from either side, but for those traveling by car, the route from the east is better, as the roads are smoother.
