Relax late into the night with 3 saunas and a deep cold plunge bath
Yamaguchi Ube City
Located close to the central downtown area of Ube, Frespland Kattano-yu is a bathing facility that stays strong into the late night, open from 10:00 on weekdays and from 9:00 on weekends and holidays until 2:00 the next morning. In addition to a large public bath with saunas, it also offers a capsule hotel, a rest area, a restaurant, and even a game center and batting center, making it a comprehensive health and wellness bath complex with leisure features, one of the largest in the western part of Yamaguchi Prefecture. Its generous appeal, where you can drop in easily after work or to finish a late-night drive, is why it has long been loved by local guests.
TypeSpecialty Bath
An artificial carbonated spring water bath said to be highly effective for relieving fatigue. Fine carbon dioxide bubbles envelop the whole body, promoting circulation and gently warming you from within. It is an ideal tub for soothing a body worn out by working late into the night, and its gentle temperature encourages longer soaks, making it comfortable and relaxing. Enjoyed alternately with the sauna, it gently eases deep fatigue.
TypeSpecialty Bath
The outdoor bath area features a variety of tubs, including an atmospheric stone bath, a lie-down bath that lets you fully relax your whole body, and a private pot bath. It is an open, refreshing space where you can take your time and enjoy bathing under the blue sky or beneath a sky full of stars. A wide selection of relaxation chairs, including infinity chairs, is arranged throughout, creating an ideal environment for outdoor air bathing after sauna use.
Sauna TypeDry Sauna
Stove TypeInfrared Heater
Capacity20people
The main sauna in a 3-tier straight layout, equipped with a gas-powered large far-infrared stove. It has a TV and offers a comfortable stay, and while the room is spacious, the stove's radiant heat still reaches all the way to the top tier, making it a full-fledged setup.
Sauna TypeSteam Sauna
Capacity10people
A steam sauna that incorporates the benefits of binchotan charcoal, with steam constantly rising from the stove to keep the room highly humid. It is expected to offer deodorizing, purifying, and circulation-boosting effects, and its gentle heat makes it easy to stay for long periods. Its flexibility is appealing, as you can use it as a second round after sweating in the dry sauna, or as your main sauna on days when strong heat feels too much, adjusting it to your own rhythm.
Sauna TypeSalt Sauna
Capacity8people
You can spend time slowly rubbing salt into your body and waiting for the sebum to dissolve and your skin to regain its smoothness. A TV is installed, which is a nice touch that lets you enjoy the effects of the salt without worrying about the wait. A shower is available at the exit, and the flow is well designed so you can rinse off the salt and sweat cleanly before moving on to the next bath.
Water QualityTap Water
Capacity6people
A spacious cold plunge bath that is kept at around 16°C year-round through circulating cooling, and is deep enough to stretch out your legs and submerge yourself up to your shoulders. Its depth is just right, helping to sharply refresh and tighten your body after warming up in the 3 kinds of saunas, making it a core part of the sauna routine.
