水上山荘 Minakami Sansou

casual Ryokan/Inn
Minakami Sansou / Gunma Minakami・Tsukiyono・Sarugakyo・Hoshi 57


Tanigawa-oka is one of the famous mountains of Japan and the Tanigawa hot springs comes from that area.
Minakami Sansou is tucked in this area.

From the lobby and the guestrooms you can enjoy a great panoramic view of nature.
In one of the chairs in your guest room, have a seat, relax, and appreciate the view. It may sound like nature is having a party all on its own.
Here you can forget the noise of the city and simply relax.

The hot springs in the larger bathing area and in the individual rooms have been given a 5 star rating by the Hot springs Association of Japan.
3 different types of homemade blends of minerals come out of 3 different spouts. The combination is determined based on the weather of the day to create the perfect bath.
The rock seats in the bath are placed at perfectly calculated locations.
During the day enjoy Tanigawa-oka and at night enjoy our night sky!

Along with the beautiful view we also have the flavors of the season to offer. Please enjoy a menu that changes monthly to be most appropriate to the season.
These ingridients have received the best of nature.
You can receive the best because there are only 17 rooms.

Rooms, Baths, Cuisine: At Minakami Sansou we offer the proper seat to allow you to relax in whatever situation you are in. Here by "sitting" you can feel the wonders of this lounge. 
Enjoy an adult's vacation wrapped in relaxation.

*This is a non-smoking hotel.

The corridors are cold; dinner was not delicious at all; the water level of the outdoor onsen was ridiculously low: it seems that most of the hot water was drained away due to poor management.

Read more ラウンジ・部屋には カメムシ(テントウムシ?)複数いましたが、谷川山系を近くに見渡せる場所であることを考慮すればこんなものでしょう。とにかく谷川山系をラウンジ・部屋・風呂全ての場所から しかもこの時期雪をかぶっており、日の光のあたり具合で風景が変わる事には驚愕しました。風呂付(半露天ということでしょうか?)の部屋が取れました。広い窓を開ければ実質露天風呂、温度・作り(半身浴で背もたれあり)とも申し分なし。泉質の良い温泉は体の悪いところに温度が入ることがわかるのですが、まさしくそのような泉質です。ただし、若干狭かった。そのため大浴場・露天風呂にも行きましたが、大浴場ぬるめ、露天は温度が低い(宿泊日-5°まで気温急降下したことが影響しているとは思います。評点4点はこのため)。夕食・朝食とも、質は十分満足(特にヒラメのこぶ締め、イワナに揚げネギかけた料理、吸い物系はうまかった(ただし、鯛からうまみ出しすぎ、鯛が目的ではないので問題なし。ポロネギではなく、下仁田ネギ使えませんでした?)・量は純分(個人的には少なくてもよい)、配膳係の方の心使いも少なからず、行き過ぎずといった感じです。 アクセスには改善の余地あるかもしれません。ナビ設定してたので何とかいけましたが、それでも2回違う道に入り込みました(看板だけではたぶんたどりつけない)。チェックイン14:00です。早めにチェックインくつろがれる事お勧めします。また、行きたい宿が増えました。

There were several bugs (ladybirds) in the lounge / room, but considering that it is a place that can see the Tanigawa mountain system in the vicinity, it would be such a thing. Anyway, the Tanigawa mountain system was covered with snow from all the lounges, rooms and baths and this time and it was amazing that the landscape will change with the lighting of the sun. I took a room with a bath (I hear that it is half open air?). It is perfect for a real outdoor bath, if you open a large window, temperature creation (with backrest in half-bath). Springs with good quality springs show that temperature enters bad places, but it is just such spring quality. However, it was a little narrow. Because of that, I went to a public bath and outdoor bath, too, but the bathroom lukewarm, the temperature of the open-air is low (I think that the sudden drop of temperature until -5 o'clock of the room has affected.There are 4 grades for this) . Both dinner and breakfast, the quality was satisfactory enough (especially flounder of the Japanese flounder, dishes deep-fried in Iwana, the soup stock was delicious (However, it is delicious from the sea bream, so there is no problem because the sea bream is not purpose, so it is not polonegi , Shimonita Onegai could not be used?) · The amount is purely (it can be few personally), the use of the caterer's mind is not a little, it is feeling that it does not go too far, there is room for improvement in access I managed to go somehow because I was setting navigation, but still I entered a different path twice (probably not alone with a signboard) Check in is 14:00 Check it in ahead of time Recommend In addition, the number of places I want to go has increased.

We stayed in a room with open-air bath. Although the hot spring of source sprinkling was hot, it was the best hot water which turned out to be a good hot water temperature when opening the window. I liked the bath in the room from the public bath. The oldness is felt, but the feeling of cleanliness was not bad. Hospitality was able to spend good feeling well everyone. There was transfer service, too and was good. It was a relaxing inn and it was possible to enjoy the hot spring slowly.
