The view from the windows wasn’t that great

Food. Onsen staff

Modern and luxurious building but traditional ryokan inside with spectacular private onsen located on top floor. Highly professional and exquisitely caring staff that can provide also transfer from Yudanaka station and to Snow Monkey Park free of charge. Dinner and breakfast simply fabulous both from a quality and variety point of view. Spacious, clean and comfortable room have made our stay at Suminoyu memorable. Highly recommended

Stayed one night, but the experience was worth the trip from Nagano. Public warm bath, good traditional dinner and breakfast. A bit far from the station but the owners picked us up (7 people) at the station...

Everything was great.

The food was amazing, both dinner and breakfast. Delicious, healthy, beautifully-presented and leaning heavily on locally-sourced ingredients, especially a gorgeous assortment of mushrooms. The staff were consistently wonderful, helpful and warm. Before we arrived, we thought that the ryokan was a little pricey, but once we saw the quality of the half-board, it became clear that it is in fact excellent value for money. A delightful surprise.

It was a great stay, very relaxing, and the food was excellent. I only regret having to leave in a rush because I had poorly planned my day - would definitely have liked to leave with more calm.

Very beautiful surreal experience at Shibu onsen and Suminoyu was the cherry on the icing . Everything was just perfect . Right from the pick up to the drop off everything was so well taken care of . Keep it going guys ❤️

No complaints at all.Exceeded our expectations.

Wonderful ryokan experience at very reasonable price.Large room, comfortable base for futon style bedding.Kaiseki dinner was amazing.Wonderful staff. Dropped our luggage at second hotel in Shibu onsen. Very few places open for dinner in the town, as close to the end of season, recommend booking half board.

The way the staff went above and beyond with their service was exemplary. From finding large enough wooden sandals for us; recommending and facilitating a sightseeing tour; offering free use of the lovely kimono for evening meals; and looking after us when illness struck on checkout day- the personal care the owners and staff for our real and perceived needs was first class.

I liked nearly everything though was surprised they only set out our futon beds the 1st night, but didn’t put them away the next day and then set out our futon the 2nd night we stayed. That may have been my fault because when aimed at check in if I wanted “cleaning” both nights we visited I said no thank you. I was unhappy we had to leave so early after check out because the hotel onsen is being cleaned from 10-14:00 and when you check out you lose your key the the 9 onsen bathhouses in Shibuonsen onsen. So we kind of had to get moving on out of town right at check out. I did really appreciate and the shuttle buses Suminoyu provided. They picked us up from Yudanaka station, took us to the monkey park (one way), and took us back to the train station when we checked out. That was very nice!

Stunning property - excellent service from everyone we encountered. Terrifically traditional Japanese with a retro- modern twist. The meals were amazing kaiseiki style with so many delicious and special Japanese dishes using regional ingredients. Truly incredibly delicious and so worth it. Suminoyu is the real deal and it doesn’t pretend to be anything it is not.

Its location and the view from the rooftop indoor/outdoor baths. Kind and helpful staff. More than enough dinner and breakfast. And free shuttle services from and to Yudanaka station on arrival and departure, and to the nearby snow monkey park. We were pleasantly surprised by the complementary espresso after breakfast!

The hospitality of the staff from pick up at Yudanaka to the end of our stay. We were made to feel at home throughout our stay.

There was no shower in our room, but no issues for one night with multiple Onsens very nearby.

The village is small, so a quaint place to stay at the top end and very polite, welcoming staff. Upon arrival, we were provided slippers for inside the hotel and shown to our Japanese style room. Having the experience of sleeping on futons, eating Japanese food and wearing appropriate clothing (and not clogs), as well as experiencing close by Onsens, was a special experience. We got picked up from the train station by free shuttle minibus and also taken to the Snow Monkey park the next day. The food was served in a Japanese styled room and we sat on the floor eating a range of well prepared and different food, with service second to none.

Loved everything, only improvement would’ve been a shower or bath in the room, but wasn’t a big inconvenience at all to go upstairs.

Absolutely loved our stay here. Our room was gorgeous and massive, with two beds and Tatami area. The baths upstairs were amazing, the authentic Japanese meals, dinner and breakfast were amazing and the presentation was 10/10 at the tatami tables. The staff were lovely and we loved the robes we were given, they thought of absolutely everything for us. The fact you have access to other baths too is great, can’t recommend this place enough!

All was great.

The staff is lovely, the service excellent, and the food delicious. We went off-season so it was very quiet and peaceful to stroll around the little town and visit the public onsen with the yukata and shoes provided by the ryokan. The best one was the bath in the hotel though. They also offer a free shuttle service for the station and monkey park as well. We felt pampered and well taken care of at all times.

Rooftop onsen is a bit small and I was lucky to be there alone.

At the top of the village Suminoyu has a great view from the rooftop bath. Dinner & breakfast were both excellent plentiful and served kindly by english speaking staff. Shibu onsen has retained an outdated charm and you can wander around in your yukata, while you try the various public onsen.

Nothing at all.

Absolutely fantastic, the hosts were great and went out of their way to make our stay great and went a vibe and beyond with pick ups. The food at breakfast and dinner was delicious and plentiful. The Onsen was also great.

We were a traveling family of four from Canada and this hotel was the highlight of our trip in Japan. Exceptional in every way: warm welcome, nice facilities (room and onsen) and what to tell about the dinner and breakfast, we were blown away! Very beautiful presentations of dishes, along with lovely pottery. There was also free coffee and a small shop downstairs where I regret not buying their beautiful cup. Couldn't find anything similar afterwards. We definitely will come back! Thank you very much for making our stay memorable! ありがとうございます。

I had an idea that the room would be more spacious, but it was ok, all in all

Looks like a perfect ryokan experience for us, beginners. Very polite staff, kanseki dinner exactly as they describe it in the guidebooks. Their own onsen is on the top floor, with an outdoor pool (it was even snowing while we were enjoying the hot water and the mountain view). We also did the village walk in traditional costumes, visiting public onsens (all included in the price, which was pretty affordable). They also provided transfer from the station and to the monkey park

This family run hotel was superb. The dinner they served was beautifully prepared and presented. The food was delicious. It was a true Japanese experience. My wife had damaged her knee the day before we arrived and the owners were very helpful in successfully getting us a wheelchair. They really went out of their way to help and this really helped to make our onward journey possible. I would highly recommend this hotel.. and the monkey park lived up to all expectations too. It was lovely to be able to stay in the heart of an Onsen town.

We arrived on the train to Yudanaka station and walked the half an hour through Shibu Onsen to Suminoyu Ryokan. Exceeded our expectations - really friendly, amazing food and such a great experience! We went to most of the public onsen in the village with the key provided, and also the ryokan onsen (which has an open air bath). We enjoyed wearing the yukata provided. Dinner and breakfast were delicious. We decided to walk to see the monkeys at Jigokudani, declining the free shuttle bus - a beautiful walk in the forest.

Nothing. The only thing is if you dont like Japanese breakfast, you have no choice..

Excellent services, the dinner, everything is very good. And the owner accompanied us with shuttle bus untill the train station. I will surely recomended and I will come back next time.

Great staff. They accommodate our last minute request for a late check in and picked us up at the Yudanaka train station. The outside onsen is amazing, as well as the area. Beatiful ryokan to stay when planning a visit to the Snow Monkey Park or just to spend time in the many public onsens in the area.
