The staff was extremely nice, using Google translation to explain everything to us. We went in the evening at around 7.30pm and there were only a few locals. The ladies part has 5 pools (1 inside and 4 outside) and the mens part 4 pools (1 inside and 3 outside). We can recommend this experience!

We got special price of 500 yen entrance during our stay at Guesthouse Azito & Bar as part of their offer. There was inside bath and outside. The inside was warmer than the outside. There were at least 3 baths outside. It was very relaxing. Good place to de-stress.
In cooler months, indoor warm pools are cozy for babies. Mornings in summer are less crowded.
