Closed for repairs till March 2020 (planned). I'm so lucky to have gone here before it was closed. Deep, utilitarian, concrete baths that were filled with some of the most amazing water ever. I'm sure the other hotels have the same water, but the bathhouse itself was so magical. With a pH of 9.62 this is not just a "bihada" 美肌 beautiful skin bath, this water felt like nothing I've ever experienced.
