Relaxing Onsen Experience

The onsen experience at Kose Onsen was simply excellent. With both public and private options available, I spent hours soaking in the soothing waters. The temperature was perfect at around 42°C, leaving my skin feeling rejuvenated. The peaceful surroundings added to the overall relaxation, making it a highlight of my stay.

Delicious Kaiseki Meals

Every meal at Kose Onsen was good! The kaiseki dinner was beautifully prepared and showcased an array of traditional flavors. Breakfast was a lovely Japanese spread as well, providing a wonderful start to the day. Although I didn't have the option to choose my meals, everything served was delicious.

Comfortable Japanese-Style Room

I stayed in a Japanese-Style Quadruple Room, which was spacious and comfortable. The traditional decor created a warm ambiance, and I appreciated the futon setup, which added to the authentic experience. Plus, I had a beautiful view of the small stream flowing nearby, enhancing my stay even further.

I had a wonderful stay at this hotel, nestled on a mountainside next to a peaceful stream. The rooms were clean and spacious, providing great comfort after a day of exploring nature. The staff was incredibly welcoming, which added to the overall experience. However, the dining options were limited, and I found the bus connection to be infrequent, making it slightly challenging to venture out. Still, the value for money was quite good considering the beautiful surroundings.

My stay at the hotel was mostly enjoyable with some highlights and a couple of downsides. The surroundings were absolutely stunning, with plenty of walking trails to explore right next to a quiet stream. The rooms were quite spacious and well-equipped, but the Wi-Fi left a bit to be desired in terms of speed. Additionally, the dining options could have used a bit more variety, especially for breakfast. Overall, I felt it was a great spot for a relaxing getaway.
