I've been very disappointed with this supersento considering that it could be better. The last time I was in the Thai themed half much of the plants were dead, the salt sauna's door was rusted and smelt strange. Thankfully, the Japanese side is much better with wooden and stone bath tubs of various sizes. I can't say that I like the cold water bath that puts your head right at crotch level in front of a place where many guests are walking by.
Decent, but not as good as the Kumano no Sato in Nishinomiya.
