ChōJu Izumi

Part of the Kyushu 88 Onsens list https://www.88onsen.com/spot/detail/hid/115 Price: 460 yen. Very crowded, so I couldn't take photos — attaching ones from the website (this is the men's side; the women's side has fewer windows). Inside there are 3 baths: very hot, hot (felt like 42-43 degrees to me), and cold, plus a sauna. The water is very "soapy" and pleasant. I assume the composition is on the photo — experts, please help! The website says hydrogen carbonate spring. Soap, towels, and hair dryer available for an extra fee. There are a couple of lockers at the reception; the changing room lockers don't lock. No milk — just a vending machine with sodas.
