権堂温泉テルメDOME

We spent a bit more than 1 hour at the onsen. The layout map mentioned "inside" and "outside" baths, so we thought there might be outdoor onsen, but in reality the "outside" was referring to the area under the dome, where there is a lot of vertical space, and technically "open-air" after the wall reaches a certain height because it's right beside the "outside" female onsen. The "outside" bath has 8 shower booths without partition, a hot pool, a cold pool with bubbles, and a sauna. The "inside" bath has 5 shower booths with partitions, a hot pool with bubbles, a cold pool, and a sauna. Both these saunas felt different, but I cannot explain well what were their differences. We brought our own towels and paid JPY800 per person on a Tuesday evening.

Went on last day of 2025. The bath area felt outdated. There are two bath areas: indoor and one in the dome. The larger one is in the dome, but it was not clear upon entering the men locker room that there was an outdoor dome area. As a result, we spent way too much time in the smaller, indoor bath. Furthermore, perhaps it was the last day of the year, the staffing was short. There wasn’t anyone to serve food. The massage area was full. Overall, felt subpar to other Onsen that I have been in Japan.

Amazing public bath with affordable price. All signs are translated to English so if it is your first time bathing your won't be lost. Additional gem is jacuzzi with cold water - I think this is the first time I've seen that and it is something! Probably because of New year holidays the food place was closed but you still can buy a can of cold beer (you may find chilled glasses next to the wending machine).

This is my first japanese onsen experience coming from singapore. It was really authentic as i see mostly locals around and the facilities are clean and well maintained! Very worth the all day use + towel rental for just 1000yen. There is body wash, shampoo and conditioner in the onsen. I spent an hour there and 30mins to change and dry my hair. They have hairdryers too! Highly recommend

If you love the sauna, this is the place for you. There is an automatic finnish sauna（loyly） with a cold bathtub. Price is 700yen for week day and 750yen for weekends which is reasonable. Highly recommend.
