Uruoikan is a hot spring facility in Nagano City, next to a rocky hillside and the Susobana River. The onsen is a 100% natural onsen and has outdoor and indoor baths, saunas, and eating options. You can also treat yourself with massages, facials, steam treatments, and more!
The view from the outdoor onsen is beautiful in every season. Just see the photo below for an impression of the winter scenery. In autumn, the trees are colored golden and red, spring sees the leaves colored a fresh green, and summer has rich green trees with cicadas chirping.
The onsen facility has two main sources of volcanic water that create the two different sorts of baths. One of the sources is used for outside baths. This water is red-colored and salty, and is said to heal you from neuralgia, muscle pains, relieve you from fatigue, hemorrhoids, intestinal problems, and many more.
The inside baths are made up of phosphorous, salty water and clear-colored. The water is said to have skin-clearing properties and helps against chronic women’s diseases, diabetes, and cuts.
The onsen is divided in two parts, to separate women and men. The two onsen, called Shiroiwa no Yu and Ryusen no Yu, have different facilities attached to them. Read more about the details of the baths below:

Onsen Rules about Tattoos:
Since most of the visitors to the onsen are locals, and locals generally have strong feelings about tattoos, people with large tattoos are not allowed to enter the hot spring facility. If your tattoo is only small, about palm-size, you can get a tattoo seal to cover up at the front desk of the building. Then you’re ready to get into the hot spring baths.

If you’re staying in hotels in the center of the city like Kokusai 21, you can easily get to the onsen within 10 minutes on foot. Hotels close to the station are not that close by but might have a shuttle bus to the hot spring available. Best is to inquire directly to the hotel.
