Onsen Camp Shima Blue / Gunma Shima・Azuma・Kawarayu 4


Shima Onsen is surrounded by nature and located in a tranquil setting in the Gunma prefecture. The name "Shima" (literally 40,000) comes from legend that this onsen was a 『miracle fountain that could cure 40,000 diseases』.
At Onsen Camp Shima Blue, you can enjoy a luxurious glamping experience with your own Shima Onsen spring fed outdoor bath. 

Glamping is a term that combines the words glamorous and camping, providing a luxurious outdoor camping experience. Enjoy outdoor activities like barbecuing and stargazing and then spend the evenings relaxing in a luxurious space. 

At Shima Blue, each of our glamping rooms has a unique style and also comes with its own natural spring outdoor bath. 

True to our concept of 「a private adult atmosphere」, guests can experience a luxurious and private stay where they can gaze out at the mountain scenery as they soak in the onsen and listen to the gentle babbling of the streams in their refined space.

For our guests who want to feel the warmth of Shima Onsen, spend time in the great outdoors, and experience outdoor activities, Onsen Camp Shima Blue is the perfect place for you. A unique and special experience awaits you.

Read more 部屋のセッティングで何点か不備があった。部屋、風呂などはかなりカジュアルな感じがした。朝食の選択肢が少なかった。・・・等強いて改善点を挙げれば何点かあるが、部屋については、窓外の眺めも良く、ベッドの寝心地も良かったし、サービス面では、若いスタッフが一生懸命やっている感があり印象は悪くない。朝食も味は良かったと思う。 概して言えば、値段なりに満足できる宿だと思う。鄙びた温泉街にこうした都会的な印象を受ける宿泊施設があるのも選択肢が広がって良いのでないか。

There were several flaws in the room setting. The room and the bath felt quite casual. There were few choices for breakfast. ... There are several points to improve, such as improvement, but the room has a good view outside the window, a good bed comfort, and there is a feeling that the young staff is working hard in terms of service The impression is not bad. I think the breakfast was good too. Generally speaking, I think it is a hotel that can be satisfied with the price. It is not a good idea to expand the options as there are accommodation facilities that receive such urban impressions in a hot spring resort.

とても気持ちよく、素晴らしい時間を過ごさせて頂きました。ありがとうございました。 朝ごはんを、あの気持ち良い部屋のバルコニーで食べられたらもっと幸せです。 また泊まりたいです。

It was very pleasant and I had a wonderful time. Thank you very much. I am more happy if I can eat breakfast on the balcony of that pleasant room. I want to stay here again.
