"Classic Japanese interior with tatami flooring but more modern bedding. Walls are thin so be careful not to be too loud and disturb the others. I could hear the conversation of others when they walked by my door and in their rooms when I walked by theirs. Onsen was nice and has a small covered outdoor section. I went inbetween the peak seasons and you can see the the town itself asleep, so many shops were closed. I speak Japanese but the staff were quick to double check if I needed things to be explained in English.
I wouldn't bring a big loud group here. I do recommend for a classic quiet, slow, relaxed, Japanese ryokan."
