I used it for a day trip bath. If you use it on weekdays when there are no guests staying, you can almost reserve it for yourself. It's cheaper than the nearby public baths, and there are fewer people, so it's great. It's a place I don't really want to tell anyone about. I visit regularly.
I happened to search for a day trip hot spring on the internet and decided to visit. You can take a day trip to the hot springs at the inn. You can also use the lounge, where you can relax on the low sofa, and the fireplace in the atrium is nice, and the wind is circulated by a fan, so it's warm. The baths are both indoor and outdoor, and although they are not large, the wooden textures are comfortable. Norikura's Hakudoku Onsen is the best.The scent of sulfur makes you feel like you're bathing in a hot spring.
A day trip hot spring facility in Norikura Highlands! The milky white hot springs are the best! They are also open early in the morning, around 6 a.m., which is not available in this area, which is helpful. I used a private bath, but it was bigger than the private baths I've been in so far, and there was also an open-air bath. It's in a separate building and it's 10m outside? It was a walk-through system. It's a separate building, so I was able to relax and have complete privacy.
