Super smooth water (美人湯) that leaves your skin slippery smooth and a giant rooftop rotenburo, you can't do much better than that. This is a very popular bath in an area with not much competition so it's often busy. The changing room is small and crowded and there isn't much room in the lobby to sit around after your bath. Those are only two small complaints. This is a quality supersento and worth taking the drive, or easy bus ride to experience. The large city park neighboring the bath is also fun to explore and has great sakura in the spring.
