Onsen Camp Shima Blue / Gunma Shima・Azuma・Kawarayu 67


Shima Onsen is surrounded by nature and located in a tranquil setting in the Gunma prefecture. The name "Shima" (literally 40,000) comes from the 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.

It was a pity that such a stuffy stuff fell on the sofa in the room. I was afraid of seeing a lot of spider webs like a wooden fence on the bath. I thought that it would be better to clean the corners of the terrace. The other rooms were beautiful and cute!

This time I stayed at Safari Black for the first time, but there was a disappointing part about the essential room facilities (especially around the water). By the way, at the time of check-out, I told the staff about the following contents, but said that the management side does not readily respond to what they requested. Although the staff are friendly and feel good, the management side is unfortunate, but I would like to expect further improvement by describing it in this review. [Disappointing point] ・ There was only half of the hot spring in the open-air bath, and it was wet. The amount of hot spring water flowing from the source is also slightly warm. I asked the staff to increase the amount of hot water that came out, but after a while ... Because it became better than the beginning, I put up with it. ・ If you think that the shower has come out vigorously, you will soon lose momentum. Repeat that. I feel a lot of stress in the shampoo. ・ Like handwashing faucets. If you think that it came out occasionally, it will be clogged as if it has no drainage capacity. ・ There are no indoor slippers. Instead, there is a rubber sandal (coca-cola guy) for indoor use. Cannot be used due to hygiene concerns. Other than that, the ingredients of BBQ were delicious, and I was satisfied because I was able to spend a relaxing time listening to music in the room while being rocked by a hammock while listening to the river. There is a reasonable accommodation fee (about 76,000 for two people during the Bon Festival), so I would like facilities to match that. I would like to ask again if the above is improved.
