Very fun, child friendly sento built in large open space on 4 floors. My daughter enjoyed the rotenburo the most, but I think that was because she was having fun making silly faces at some other kids. The cold water bath, also outdoors, had a great fresh smell to it that was really relaxing. All of the washing areas were spread around the baths on angles and in corners. It makes washing off fun having your own little area. There is also an bath with ultrasonic waves being sent through it which, according to the sento's website, is good for your metabolism. The two different bathing areas change everyday.
