Yumoto Itaya is a hot-spring inn at Oku-Nikko Yumoto Onsen, in the mountains of Nikko, Tochigi, with its own free-flowing sulfur source. Its water is pale green or milky white and smells strongly of sulfur, which the inn calls the mark of a real onsen. Before you book, three things matter: the official site does not give check-in or checkout times; dinner starts at 18:00; and the baths are one set for men and one for women, never swapped.
Why stay at Yumoto Itaya?
Yumoto Onsen sits by Lake Yunoko; the inn’s own sightseeing page lists a walk around the lake from the hot-spring town. The inn says its water is said to be the fourth most concentrated sulfur spring in Japan, after Manza, Tsukioka and Takayu, and that it is soft, neutral to slightly acidic, and rich in metasilicic acid. According to its Japanese site, the spring was found in 788 by Shodo Shonin, the monk who opened Nikko, and in the Edo period the shogunate named hot-spring keepers here, when Itaya began taking in travelers. In the Showa era, Yumoto became the first spa town designated as a national health resort.
From the rooms, the inn says, you see Mount Nikko-Shirane, the highest peak north of the Kanto region. For a wider plan of the area, see our things to do in Nikko guide.

The sulfur baths at Yumoto Itaya
What is the water like?
The inn draws from its own source and lets the water flow straight through the baths. It describes the temperature as lukewarm, made for long soaks, and the color as pale green that changes day by day, clouded by mineral flakes called yu-no-hana. Expect a strong smell of sulfur on skin and towels.
How are the baths laid out?
The bath building, called Hanare no Yu, has one indoor bath and one open-air bath for men, and the same for women. The Japanese page adds that they are not swapped between men and women, so you can use both on the same side at any time of your stay.
When are the baths open, and is there a private bath?
The official pages do not give bath hours and do not mention a private bath. Ask at the front desk when you arrive.
Can I bathe with a tattoo?
The official pages say nothing about tattoos. Ask the inn before you book. Our tattoo and onsen guide explains what to ask and how cover stickers work.

Meals at Yumoto Itaya
What are dinner and breakfast like?
Dinner is a seasonal kaiseki course of local ingredients from 18:00, and breakfast starts at 8:00. Both are served in the private dining rooms, Sanmeitei, where every room has a table and chairs, or in the Japanese restaurant, Asunaro. The inn says each dish is cooked to order and carried to your table at the right temperature. Its kitchen is led by a Japanese-cuisine chef working with a French-trained chef, and the site announces a new head chef from January 2026.
Dishes the inn shows include Nikko yuba (tofu skin) served fresh as sashimi, a Tochigi beef fillet steak, and its own steamed rice with sansho pepper and small fish. Extra dishes you can order include grilled or fried iwana char and iwana bone sake.
Can the inn handle allergies or a special diet?
The official pages do not mention allergies, vegetarian meals or other diets. Write to the inn before you book, through the official contact form, and list exactly what you cannot eat.
