A small onsen in a secluded area on Aokimurra village near Ueda shi. One can enter onsen with a very minimal fee of ¥200. Be aware there are no shampoo or soap provided inside the bath and one has to bring their own. When I visited there was guy with large body tattoo, so apparent it is tattoo friendly. There is small car parking in front of entrance but reserved for people with disabilities. There is a bigger car parking for 7-8 cars on a upper level just behind it connected with a stairway that connects to side of Tazawa onsen.
Fantastic experience. Amazing staff that are super kind and lovely. Very exclusive and luxurious onsen and I do recommend!
I had previously seen this hot spring listed as a must-visit in Nagano Prefecture, and this was my first visit.
It's a refreshing, simple sulfur spring.
The showers and faucets also have the strongest sulfurous smell of any hot spring.
Enter the building → put your shoes in the shoe lockers on either side → purchase a ticket from the vending machine to the right of the reception → proceed to the reception.
Those with valuables should put them in the valuables locker in front of the changing room before entering.
The valuables locker is a 100 yen returnable type.
There are only baskets on the shelves in the changing room!
And there are no hair dryers, no body soap, and of course, no sauna!
There are only about 5 washing areas, so if you go at a bad time, you may have to wait for one to become available, and the changing room can get crowded.
There is only one indoor bath, and ideally, it would fit about 6 people comfortably.
Don't forget to keep your valuables locker key with you before entering the bathroom! The water quality is good, and I'd say the temperature is around 39-40 degrees Celsius.
The area around the building and the turn into the parking lot is narrow, so larger cars and inexperienced drivers should be especially careful.
If your car is extremely low to the ground, be prepared to scrape your aero kit.
I was able to get through easily in a 50 Prius with lowered suspension and a full factory aero kit.
The towels for sale have your name on them!
I'm so envious of the locals who can bathe here almost every day for just 300 yen (lol).
I'd love to stop by again if I have the chance!

I arrived around 4pm on a weekday. The parking lot could accommodate about six cars. The exterior of the building had a nice, shrine-like feel. There was a ticket machine right in front of me as I entered the entrance. I bought a ¥500 adult ticket and handed it over to the receptionist next door. There was a sink in the changing room, but no hair dryer. Contrary to the exterior, the bathing area had a single tiled bathtub with two other guests. There was no shampoo or body soap in the washing area. I headed to the bathtub. It looked clear and had a slight sulfur smell. It was lukewarm to me, maybe around 36 degrees. I think? If you like long baths, this is definitely worth it.
