Very traditional rooms and beautiful gardens in a great location.

This a small Ryokan which is very authentic Japanese style. No English spoken but this adds to the authenticity. We loved the natural accommodation which was exactly as shown on the website. Excellent meal provided in the evening and an enormous breakfast which we were not expecting so was a bonus. We lounged about in out Japanese clothes provided and Thoroughly enjoyed our visit to this clean and peaceful retreat.

Yamagaso was a wonderful surprise after a very disappointing stay the week before at Arima Onsen. This property is beautiful and our room with a garden view was more pleasant than any any place that we’ve stayed around the world. The rooftop onsen is a very special experience to not miss. The breakfast and dinner was superb and each dish presented was a work of art. All that being said, what made this place really stand out was the service provided by Kimiko. Her attention to detail, explaining customs, preparing the room and serving meals made our experience very special

A lovely authentic Japanese experience. Very welcoming hosts. Food was plentiful and to a high standard just not to my Western palate. Very fish orientated. A menu would have been good to help identify some of the dishes. We loved getting dressed into our Yukatas. No Wi-Fi in the room but available in the lounge. Convenient for Hakone station.

Amazing experience of staying in Japanese Ryokan. It is a bit dated but very authentic and enjoyable for couple of nights

Very nice Japanese style resort with nice half board dining and private bath

Lovely old Japan style hotel The meals were amazing We loved the beauty and service at the hotel Thank you

Booked through hotels.com. I thought that, since this was a ryokan and other reviews mentioned the amazing Kaiseki style dinner they served, that dinner would come with my booking. There was no additional option when booking to specify whether I wanted dinner or not; so I figured it was implied/included, as it has been for other Ryokan bookings. Turns out, somehow, despite being $600+ a night, my booking did NOT include dinner. This wasn't made clear to me until after dinner never showed up the first night. So, after bathing and putting on my yukata and relaxing with a beer, I had to trudge back outside in my streetwear where the only thing open was an Izakaya with a 1.5 hour wait. I complained to the staff in the morning, and they refused to do anything to make it right. If I wanted dinner that following night, I'd have to pay 20,900 yen more. This overall RUINED my experience for these two days of my trip, which were also, by far, the most expensive accommodations. Given this I cannot award any stars to this place. The actual room and hotel grounds were nice, but not worth getting my trip screwed over. DO NOT BOOK. Find something else, one that will not screw you over on the experience.

We came to Japan to experience the culture. Hakone hotel Sensei was perfect. Beautiful room with private onsen. We also experienced the open air onsen. The dinner and breakfast was fantastic. My only complaint was too much food.

Loved my stay here! Everything was well organised, the semi-private onsen was always free when I wanted to go. The little ryokan was comfy and warm. Would recommend.

The stay at Yamagaso was a unique experience. I recommend doing the half board as the Kaseiki dinner and the breakfast were fantastic! We also love the private onsen and the convenient access to the other onsen at the hotel next door.

Wow! What an amazing experience. We had a beautiful stay , our only regret was that we could not stay longer. We highly recommend this traditional Ryokan. Kimiko our host is a beautiful souls and made ourv stay that much more special. The food is incredible, the private ohnsen was better than expected. You will not be disappointed with a stay here.

We had a fantastic stay at Yamagaso. We were able to drop our bags off at the main hotel so we could go sightseeing before check-in. Dinner was a delicious kaiseki meal served in our room. It was great having our own private bath in our villa with hot spring water. Our host Momo-san was sweet and very helpful. If we ever return to Hakone we would love to stay here again.

Gorgeous and serene ryokan in Hakone, beautiful facilities and rooms, amazing kasekei dinner right in our suite!

The ryoken is absolutely beautiful and the staff are wonderful. It's a picturesque place to stay and not too far from the station or restaurants/bars. It was an amazing experience to stay here!

A very unique experience in a fairly traditional ryokan-style lodging. Hot spring readily accessible. Peaceful, soothing, and healing stay.

I had a wonderful stay! The room and property were absolutely gorgeous, the staff so welcoming and nice, and surrounding area stunningly beautiful. I highly recommend staying here and plan to visit again on my next trip to the Hakone!

Fantastic food, accommodations and staff. Could not have been happier with our stay.

Absolutely superb. Food and service was so good!

best part of my trip. highly recommended
