Suminoyu
9,5/10 Exceptional - Based on 414 reviews
Suminoyu sits in the historic Shibu Onsen district of Yamanouchi, presenting a measured, traditional ryokan experience built around its natural hot springs. The property operates communal indoor and open-air baths fed directly from the source, including a sizable hot-spring pool on the sixth floor that opens to mountain views; these bathing facilities define it as a ryokan with onsen in Shibu Onsen, Nagano. Its central location places visitors a short drive from the Jigokudani Monkey Park and within easy reach of nearby ropeways and ski areas, making the inn practical for winter skiers and shoulder-season sightseers alike.
Guest accommodation blends classic tatami rooms with a limited modern Japanese-style room offering two Simmons semi-double beds plus futon options; listed amenities include air conditioning, flat-screen TV, refrigerator, washlet toilets, yukata and a suite of toiletries. Baths are communal while most rooms include a private toilet; the property provides free Wi‑Fi in public areas, luggage storage, a shuttle service from the local train station, a footbath for quick relaxation and optional massage treatments. Meals follow seasonal Shinshu menus emphasizing local produce and a regional sake selection, served in private dining spaces on set schedules.
Practical details are straightforward: check-in begins at 13:00 (with an early-evening cutoff), check-out is at 10:00, and reception maintains extended morning and evening hours. The inn posts clear bathing-safety guidance and encourages guests to explore the town’s nine public hot-spring huts and cobbled streets in yukata and geta to sample local confections and atmosphere; nearby highlights include the Snow Monkey Park, SORA Terrace viewpoints and Shiga Kogen ski areas. For travelers seeking an authentic bathing stay that combines traditional hospitality with contemporary comforts, Suminoyu operates as a ryokan with onsen in Nagano Prefecture.

Kaiseki dinners and breakfasts were repeatedly described as delicious, beautifully presented and using local, seasonal ingredients — several guests said the meals were a highlight and very good value.

Guests loved the clean, relaxing onsen (including a rooftop rotenburo with views), appreciated all‑night access and found the hotel baths and access to local public baths a major plus.
Authentic, clean and comfortable rooms
The property felt authentic and well maintained; rooms were spotless, traditional tatami/futon arrangements were comfortable for many guests and overall accommodation was described as relaxing and spacious.
Great location for onsen‑hopping and nearby attractions
Located in charming Shibu Onsen, reviewers enjoyed the town atmosphere, easy access to multiple public baths and convenient connection to the Snow Monkey Park (some guests noted shuttle/lift service to the park).
Negative Reviews
Firm/hard pillows
Several guests found the pillows very hard and noted this as an uncomfortable detail.
Limited Western breakfast options
Some visitors said the traditional Japanese breakfast can be difficult for Western palates and would welcome a Western‑style alternative.
No en‑suite showers / shared bathing arrangements
A number of guests pointed out that showers are located in the onsen and are shared rather than inside every room, which was unexpected for some.
Driving and access can be challenging
Reviewers warned that local streets are narrow and driving/parking can be awkward; a few mentioned the ryokan is a short distance from the station (though staff pickup is offered).
Room layout and limited views may surprise some
Some guests unfamiliar with Japanese style accommodations noted the open single‑room layout (sleeping and lounging in one space), lack of Western beds for those who expect them, and occasional underwhelming window views.
