Relax in a five-tier tower sauna of overwhelming size and two types of cold plunge bath
Ibaraki Hitachinaka City
"Katsuta Akatsuki no Yu" is a large super sento in Hitachinaka City, Ibaraki Prefecture. Its biggest highlight is the towering five-tier sauna with an overwhelming scale. Powerful far-infrared heat fills the room, and the stepped layout lets you work up a good sweat at your preferred temperature level. For cooling down, there are two cold-water baths: the main cold plunge bath with a crisp, refreshing chill, and a milder cold bath that is gentler on beginners. The open-air bathing area also offers an exceptionally liberating outside-air bath experience, making it a place where you can enjoy an authentic sauna session. Other attractions include a powerful electric bath and a daily rotating bath, adding to the variety of tubs available.
