CLOSED! Sadly Saiwai-yu closed before I could post this review. Bummer. Check out their website for some photos of the baths. Decent place but pretty small. It's one of those places where the regulars have their own routes, and as a non-regular, you always seem to be in the way. The cold water here was non-chlorinated and felt good. Two saunas here with a free dry one that could fit about three people. The steam offering could have been a bit hotter for my taste.
