A sulfate-chloride spring led by sodium and calcium, drawn as the combined Shibu Onsen source blending Hira-no-yu, Yakushi-no-yu and Tobi-no-yu. Sulfate lends a settled, mineral body while the chloride content gives a salty, heat-retaining finish, all at a weakly acidic pH. At the wellhead the water is faintly yellow and clear with a slight iron taste.

About

Hishiya Torazo is a wooden ryokan in the middle of Shibu Onsen. The building holds three separate bathing areas, each fed by a different spring, so across a stay you get three distinct waters (men's and women's swap between them morning and evening, no mixed bathing). Washing is done right at the tub's edge rather than in a separate shower stall. A garden rotenburo once favored by the late Edo scholar Sakuma Shozan (佐久間象山) can be booked out for a private soak with family or a partner. Founded around 1620, the inn keeps its old wooden rooms and serves a kaiseki (会席) dinner and breakfast in a private room. It sits close to the middle of the onsen town, an easy walk to the public bathhouses and the bus stop for the Snow Monkey Park.

43. Hishiya Torazo, Shibu Onsen, Nagano ★★ I stayed here like at a ryokan. The owner is very nice, the building is pleasantly old, and there are various figurines placed around separately. He looked at the matryoshka I gave him for a long time with interest, and said his wife had been in Russia. The food was tasty too. At the ryokan, they give you a key for visiting 9 public onsens in Shibu Onsen. 1. One bath area is indoors with stained glass, and it changes by gender. Inside there are two baths. The water looks cloudy, and I did not especially remember the smell. As for the water temperature, one bath was normal, the other was hot. 2. The outdoor bath is basically private, at the entrance to an empty one, the first visitor marks it with a sign as male, female, or private. In other words, whoever gets there first gets it. The water is cloudy, and the temperature is a little below average. 3. The second bath area also changes by gender. One square bath has clear water at a normal temperature, and the other bath is among rocks with mildly warm water. I liked everything, I can recommend it. 03.01.2024 04.01.2024
