Kurokawa Onsen (Ryokan Yumotoso)

Operated by · 旅館湯本荘

Iron-bearing
+ 単純鉄泉(硫酸塩型)

An iron-rich simple thermal spring of the sulfate sub-type (formerly classified as tanjun-ryokuban-sen). It carries a good deal of iron and oxidizes reddish-brown on contact with air, while a pH of 3.31 makes it acidic and faintly tangy on the skin. With about 35 mg/kg of dissolved iron and 117.7 mg/kg of metasilicic acid, it sits firmly in the iron-bearing family.

11. Ryokan Yumotoso, Kurokawa Onsen ★★ I visited for a day trip; it is located almost in the center of the village. Usually, day-trip access is available from 08:30 to 21:00 for public baths and from 08:30 to 19:30 for private baths, with occasional closed days during the week. The public baths alternate between male and female, and are part of the Kurokawa tegata (bath ticket) system. There are three options for private baths, priced at 3000 yen. Guests staying overnight have access to an indoor bath. There was a funny story at this ryokan. Early in the morning, I entered the men's bath, but while I was there, they changed the curtain at the entrance, and in fact, I ended up leaving from the women's bath. About the onsen: 1. The first option alternates the baths by gender. The outdoor bath is made of stone. It used to be more open, but now the small roof was removed and the large upper outdoor roof was extended, so the bath became semi-open. The view includes forest, bamboo, and stones. The water is clear with a slight tint. Temperature is 40.5°C. 2. The second option alternates the baths by gender. 2.1. Wooden bath. View of trees and the opposite riverbank. The water is clear, temperature 41°C. 2.2. Stone bath. View of the river, trees, and opposite bank. The water is clear, temperature 38°C. It's comfortable to lie forward on the edge of the bath and relax with the beautiful view. 3. Private indoor bath Kamaburo. The bath is shaped like a stone coffin. The water is clear, temperature 41°C. The air inside is good to breathe, and you can open the window. A cool place with very strong baths, recommended for visiting. 27.12.2023 08.04.2025 30.12.2025
