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

야마가소는 전통료칸이지만 주위 다른현대식건물이 너무 많음 전통료칸을 찾는 여행객에게 유용하지 않다는생각. 비추임

離れは雰囲気も良く、とても良かったですが、かなり古い建物で全体が歩くたびに軋みます。 部屋付き内温泉ということで楽しみにしていましたが、1人が体育座りになってやっと入れるほどの小さいお風呂で、ゆっくりは入れませんでした。 写真では大きそうに見えたので、残念でした。 その代わり、離れの客が使える家族風呂や、本館の方と一緒に使える露天風呂、大浴場がありました。 サービスも丁寧でとても良いのですが、玄関にお給仕スタッフさんからのノックが来たらすぐに出ないと、大声で叫ばれ、回り込んで窓までガンガンと叩かれ、急かされている感じが多々ありました。内線電話があるのだから、急ぎや食事の時以外は電話で教えて欲しかったです。 高級旅館という感じの落ち着きはありません。 食事はどれも美味しく、量もちょうど良く満足でしたが、今回は休日ということもあってか12万円以上払っているので、お夕食はお刺身や、メインのお肉などの量がもう少しあっても良かったかと思います。 全体的に、15,000円くらいで食べられそうなものたちでした。もう少し、目を引く豪華なものが欲しかったです。 電波はほぼないですが、少し繋がる程度。 Wi-Fiは、茶屋からしか使えず、お風呂の帰りに湯上がりドリンクのサービスもあるというので行ってみると、コンセントに差し込むタイプのソフトバンクエアーを導入しているだけだったので、そこに行ってもWi-Fiは弱く、動画やゲームなどはできません。 湯上がりドリンクはウィダーやお茶、コーヒー、サイダーがあり良かったです。

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.

조용히 쉬는것으로굿 서비스굿

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.

아주 전통적인 료칸입니다. 할머니의 따뜻한 배려와 미소가 오래도록 여운이 남았습니다.

너무좋았습니다. 직원들 너무 친절하고 온천도 너무 좋았고 식사 최고입니다. 또 가고싶습니다.

Das Yamagaso war relativ teuer. Wir haben dann aber bemerkt, dass an diesem Wochenende der «Bunka no Hi» (japanischer Kulturtag) war und alle Welt unterwegs. Die Begrüssung und Einführung durch das Personal war sehr, sehr freundlich und persönlich. Wir erhielten Grüntee und Süssigkeiten, während uns die Yukata und Pyjamas bereitgelegt wurden. Wir genossen die Stille, welche nur durch das Rauschen des Flusses und das Geplätscher der Bächlein und des Brunnens unterbrochen wurde. Das Zimmer war sehr gross und der Schlaf auf dem Futon war geruhsam. Es hat einen grossen Indoor-Onsen beim Hotel drüben, sowie einen weiteren Outdoor-Onsen im vierten Stock dort. Der ist etwas schwieriger erreichbar, aber auch sehr schön. Das Hotel erreicht man zu Fuss in rund 15 Minuten vom Bahnhof Hakone-Yumoto aus. Es hat uns sehr gut gefallen hier.

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!

We had the most delightful stay - nice, sweet people at the hotel, exquisite food, calm and beautiful surroundings, natural spring baths. It was an outstanding experience. We didn’t want to leave… Hope to be back one day. Thanks 🙏
