Iwasu-so
8,6/10 Excellent - Based on 36 reviews
Iwasu-so sits quietly in a wooded valley near Nakatsugawa, presented as a traditional ryokan that blends simple, unpretentious accommodation with an emphasis on regional hospitality. The property offers a mix of Japanese-style rooms with tatami and futons and a selection of rooms with Western beds, all framed by views of the surrounding forest. Meals focus on seasonal local produce and regional specialties, with menus that commonly feature Hida beef and river fish prepared in home-style courses; guests are provided yukata for in-house comfort and there are shared lounges for relaxed evenings.
The inn is centered on its radium spring source and a variety of bathing options: gender-separated indoor baths, a semi-open-air bath, and reservable private baths that guests can book for family use, making it notable as a ryokan with private onsen in Gifu. Facilities also include a sauna, casual barbecue and karaoke spaces, and on-site dining, while practical amenities cover complimentary Wi‑Fi in guest rooms and free parking. The bathing water is described locally as a clear, mild radium spring; the property promotes quiet, restorative stays rather than spa-style resort programming.
Practical access is arranged with shuttle transfers to nearby stations and easy road access for drivers, positioning the ryokan as a convenient base for exploring Ena Gorge, Magome on the Nakasendō and cycling or hiking routes through the Chūnō highlands. The setting appeals to travelers seeking a modest, service-focused retreat and authentic regional meals, and its combination of communal and private bathing options also makes it a straightforward choice when searching for a ryokan with onsen in Gifu Prefecture. Reservations are commonly advised for weekends and seasonal foliage periods.

Positive Reviews
Friendly, helpful staff
Multiple guests praised attentive, English‑speaking staff who arrange transfers, shuttle services and helped plan hikes/bike rides — many described the team as very kind and accommodating.
Excellent, authentic food
Reviews repeatedly mention delicious, authentic meals (including local specialties such as Hida beef and river fish). Dinner and ryokan‑style breakfasts are highlighted as a major strength.
Very good onsen facilities (including private/outdoor options)
Guests enjoyed multiple hot spring baths, private outdoor onsen and well‑maintained bathing areas, calling them a luxurious and relaxing feature of the stay.
Beautiful, tranquil natural setting
The ryokan’s location in nature, riverside views and opportunities to see fireflies were described as peaceful, scenic and a key reason guests chose to stay.
Traditional ryokan charm and cleanliness
Many reviewers appreciated the traditional atmosphere, authentic ryokan experience and reported that rooms and public areas were clean and well cared for despite the property’s age.
Negative Reviews
Remote location and limited access
The property is quite isolated—several guests noted it is far from towns and attractions. While a free shuttle is offered, its schedule can be limited which affects convenience.
Aging facilities and dated decor
Multiple reviewers said parts of the hotel (lobby, dining rooms and some guest areas) feel worn and in need of refurbishment, which affected perceptions of value for some guests.
Rooms small or lacking in‑room amenities
Some rooms were described as cramped for three or families and lacking amenities (no in‑room fridge, no shower curtain or mat in room baths), which disappointed guests expecting more modern conveniences.
Insects and nature‑related issues
As the ryokan is in a natural setting, several guests reported insects (including stink bugs) in rooms or on the property — an expected but bothersome aspect for some visitors.
Menu rigidity and some practical concerns (breakfast/onsen temp)
A few guests found the traditional breakfast too heavy or would have preferred simpler options (toast/eggs). Others reported limited dinner choices required at check‑in and that some baths were uncomfortably hot with no easy cold‑water options to cool down.
