Awanoyu
白骨温泉 泡の湯
Awanoyu in its valley, Shirahone Onsen · YOSHIFUMI OGISO / CC BY-SA 3.0
A huge milky-blue mixed bath you can soak in for an hour — lukewarm by design, with bathing wraps for women — at a century-old mountain inn that's no longer for families
Awanoyu has been in Shirahone since 1912, and nearly everyone comes for one thing: a 70-tsubo outdoor bath of milky, sulphurous water at body temperature (the spring emerges at 37°C), which is why guests happily stay in for an hour or more. It's mixed, but designed to be approachable: separate entrances, a women's changing room with steps straight into the opaque water, and a thick towel-style wrap lent free to overnight guests. Japanese reviewers rate it highly — 4.7 across 835 reviews on one site and 4.63 across 1,260 on another — with the bath and the attentive staff scoring highest; many 2026 reviewers mention small touches such as home-made sweets and a late-night rice ball left in the room. Indoors, a cypress bathhouse has a 37°C tub and a hotter one. Dinner is a 14-dish Shinano course with a Japanese black beef or pork main, and breakfast brings onsen-kayu, rice porridge simmered in spring water. The downsides are the ageing building and its comforts: rooms, halls and dining areas that can be cold in winter, cramped semi-private dining rooms where voices carry, food that never changes, pricey drinks, one hairdryer in the changing room, and horseflies in August. One December 2025 reviewer reported men loitering near the women's entrance to the mixed bath and felt the front desk brushed it off. Since September 2024 children aged 12 and under are not accepted.

Lo que han añadido las crónicas de estancia, publicaciones y avisos oficiales japoneses más recientes desde que se escribió esta reseña
Checked in October 2026: no change at the inn, but the official site now warns that day bathing may close at short notice because boiler-fuel supply is unstable. Several summer 2026 reviews found the outdoor bath very lukewarm, and two day visitors said the water turns slightly see-through in bright sun.
Guía para elegir habitación
Lo que recomiendan quienes se han alojado aquíRecomendadas
New-building Moegi (萌黄) rooms
The most common room type: 10 tatami plus a sunroom, kotatsu, and your own bath and toilet. Guests chose it over the main building for the in-room toilet; a couple paid ¥33,550 per person with two meals in 2021 for a third-floor room (third-floor guests get extra amenities and a free drinks corner; second floor is about ¥2,000 cheaper).
Moegi with beds, for easier access
One room with beds, nearest the lift, which the inn recommends for older guests. The lift in the new building goes down to the baths.
Mejor evitar
Main-building (本館) rooms
The cheaper option (reviewers paid around ¥21,000–22,000 per person), but toilets, washbasins and baths are shared. Some guests booked in the main building were upgraded for free — don't count on it.

La cocina a fondo
Consenso sobre el desayuno
4.4/5Onsen-kayu — rice porridge simmered for an hour in the spring water — with a Japanese breakfast; the lounge offers drinks and snacks from 8:00 to 10:00
Soak in the mixed bath in the evening or early morning, when overnight guests often have it almost to themselves; day visitors come from 10:30 to 13:30. The bath closes for cleaning 10:00–10:30 and 14:00–15:00.
Claves de la cena
4.1/5The Shinano course of 14 dishes in machiya-style private dining rooms, with a choice of Japanese black beef or mochi pork, plus iwana, Shinshu salmon and toji-soba. Most reviewers are satisfied 'in both quality and quantity', but a 2025 couple found the room 'really cramped', one iwana burnt and the other undercooked, and a tiny croquette; others say there are too many courses, the menu never changes, voices carry between rooms and drinks are overpriced.
Onsen y bienestar: la realidad
A sulphurous calcium-magnesium-bicarbonate spring, 37.3°C at the source, pH 6.3 and drinkable, flowing at 1,730 litres a minute. The inn says the hotter indoor tub is warmed by heat exchange without adding water; one booking site lists it as heated and diluted.
The big outdoor bath is mixed, open overnight, with separate entrances; women enter from their own changing room down about six slippery steps, and the water is milky so you can move about crouching (two 2026 day visitors found it slightly see-through in bright sunshine). Wraps are free for overnight guests only (day visitors pay ¥800 for a towel). Men reach it by a long corridor from the men's indoor bath; women can't go directly from the women's indoor bath. At 37–38°C it's lukewarm — lovely in summer, chilly in winter — and there are no women-only hours. Separate indoor baths (37°C and about 40°C) and small outdoor baths for each sex. No private bath.
No policy found on the official or Japanese booking sites — contact the inn. There are no private baths.

A category-by-category packing list for a snowy onsen ryokan trip in Japan from December to March: kairo heat packs (and what the maker and air-safety authorities say about flying with them), snow boots and slip-on ice grips, thermal layers, gloves and hats, lip and skin care for dry air, and a waterproof bag for walking between baths — with what to buy on Amazon.co.jp or Rakuten and what some inns lend.
