しおさいの湯

Adult admission is just 360 yen, making this a very affordable bathhouse. Because it's so cheap, it gets crowded even during daylight hours on weekdays. There's no safe for valuables, so I keep my wallet in the shoe locker with my shoes. The lockers in the changing room are convenient because they don't require coins. The sauna is small, accommodating up to eight people, but after about five minutes, you'll start to sweat. There's a storage area for sauna mats inside the sauna. Used sauna mats can be returned to the space between the changing room and the bath after rinsing off in the shower. The drinking fountain is in the changing room, which is inconvenient if you want to drink after the sauna. The cold water bath isn't incredibly cold, but it's still quite cool, even in the summer. The indoor bath has a jacuzzi and a regular bath. The open-air bath is a radium hot spring that can accommodate about three people. The massage machine costs 200 yen for 10 minutes. There may be a wait for the faucets during daylight hours, but the low price makes it appealing. When Shiosai no Yu is closed, I recommend Refre U, a public bathing facility run by Iwata City, for its low prices.

I went on December 4th, 2024. It was incredibly cheap at only 360 yen per adult. It's a small bathing facility located in a corner of a park. There's also a campsite nearby, so it would be convenient for campers. I went around 6 PM, and it wasn't too crowded, so I was able to relax. The clientele seemed to be mostly local elderly people, many of whom appeared to be regulars. I didn't expect many facilities given the low price, but the indoor bath, jacuzzi, sauna, and cold plunge pool were quite good. Both the indoor and outdoor baths are small, so it might be best to avoid peak hours. The outdoor bath is apparently from Ena's radium hot spring, and as someone who has used Ena's radium hot springs, I felt wonderfully warm, a deep, visceral warmth. Overall, it's a small facility, with only about six washing stations and five sinks, and each bath is also small. Adjusting your visit time accordingly should be sufficient. I was very satisfied with my choice!

Absolutely fantastic! I've been to quite a few public baths, but this one was exceptionally good! Perhaps because it was a weekday, the number of users was just right, and it was all adults. I think everyone was over 40? Because of that, the changing room floor wasn't wet, and it was comfortable after bathing. There was no sauna, no TV, and no one was chatting, which was very pleasant. The water temperature in the cold bath was just right, making it very comfortable. A true sauna enthusiast might appreciate this. The fresh air was nice, and it was great that there were chairs in both the bathing area and the open-air zone. The open-air zone had just the right breeze that day, which was fantastic. In short, it was great.

I stopped by during my trip. The price is reasonable at 360 yen (150 yen for elementary and junior high school students), but not only that, they also provide soap and other toiletries, and the hair dryers are free – a very thoughtful bathhouse. I also thought it was great that they have a free tatami mat rest area. Incidentally, this isn't a natural hot spring, but they use "Komeiseki" stones and have received approval as a quasi-drug for their expected benefits in treating stiff shoulders and poor circulation. Also, although the price is the same, the buttons on the ticket machine are separated for adult (male) and adult (female), so be careful not to make a mistake!

Opening hours are 10:00 AM - 9:00 PM. I stopped by here as a quick dip during my trip. There's an indoor bath, a bubble bath, a sauna, and an open-air bath, but we didn't use them on the day we visited due to strong winds. They don't seem to be that big. It's reasonably priced at 360 yen for adults. Apparently, the open-air bath uses "Nasu radium mineral sand," while the indoor bath uses "natural komyo stone." It was early evening, so it was quite crowded. There's a campsite right in front of it, and it seems many people use it.
