スーパー銭湯 青の洞窟

I've become addicted to saunas and often stop by when I have business in Chiba New Town. The only other sauna option in Inzai City is the Hot Spring Center, so I have no choice but to come here, but to be honest, it's not a particularly appealing facility. As for the bath, there is an artificial hot spring, but it doesn't feel like a hot spring at all. They apparently change the type of water regularly, but I wonder if the water really does change? I've been going there for just under a year, and there's no scent or any noticeable difference. There are three artificial hot spring baths, but the only difference is the shape and lighting, and they're all lukewarm at around 39 degrees. Since there are three, I wish they had hot water at around 42 degrees. I like the microbubble bath the best, which is around 41 degrees, but the debris that accumulates at the edge is noticeable and a bit annoying. I don't recommend visiting just for the bath. The sauna itself has an auto-louver every 7 minutes?, so although it's small, I think it's quite good. However, for some reason the path to the rest area involves a staircase, so even if you submerge your heart rate in the cold bath after the sauna, it will rise again. Also, the cold bath can only fit three people, so it's small and you have to wait quite a bit. There is only one bucket in the cold bath, which is inconvenient. The sauna can fit a maximum of about 15 people, but to be honest it doesn't match its capacity. Also, if you go on a weekend, there aren't enough chairs in the rest area. There are only four chairs with backrests. As there is no open-air bath and you can't bathe in the open air, the turnover is low and you often can't get a seat. Are they being stingy even though there is plenty of space? The path is poor and there are not many chairs, so many people end up lying down or sitting on the edge of the bath, which is very disappointing. The price is reasonable, but despite the modern facility, it is cash only, which is quite disappointing. The two-month expiration date for the tickets is too inconvenient, so I wish they'd extend the expiration date or sell them in five-packs... Updated 3/5: Apparently the bathhouse won't be open for a few days due to poor facilities, but when I asked, they said they wouldn't extend the tickets... With one day off a week, I can only effectively use it for about 50 days, so I'm not happy that they unexpectedly cut a few days off and didn't address the issue.

Parking is free for 3 hours, and if you show your ticket at the entrance, an additional 3 hours will be added, so you can take your time. Buy your ticket at the ticket machine to the left of the entrance, and enter by holding the barcode on the ticket at the ticket gate on the far left. Overall, it's a nice facility. It's a shame that there are only 4 vertical lockers for suits in the changing room, and I'd like a few more. The washing area is new, so the shower and faucet buttons are the first type I've seen, but they are easy to use. There is no open-air bath, but all the baths are below 40°C, so you can relax in them. The jet bath has gentle pressure. There are two types of electric bath, strong and weak, and the carbonated spring is warm so you can stay in it for a long time. The silky bath is also relaxing. There are 4 seats in the sauna on the right, 2 levels in the main bath for 7 people, and about 5 people in the bottom level. It is 92°C, and there is an auto-louver every 10 minutes, so it is quite humid. The cold bath is 17-18°C and can accommodate up to 4 people. There is a rest area at the back of the bath. There are three chairs with backrests and armrests, and several other simple black chairs, but they are used as ottomans and are not being used to their full potential. They have taken the trouble to create a relaxing space that resembles a starry sky, so if they placed a few more chairs with backrests along the wall, it would turn into a great rest area for sauna users. It felt like a real waste. If you go up to the second floor, there is also a glamping-style rest area and working space. You are free to bring in food and drinks, and there is a microwave. Overall it was a great facility. I would like to visit again.

It's a 15-minute rental bicycle ride from Chiba New Town Chuo Station. A hot spring facility attached to a fitness club. The bathroom is on the first floor and is fully equipped with various hot water baths, an auto-loyly sauna room, an ice-cold cold bath with a chiller, and a relaxation chair. The auto-loyly only gets a little hot, however, so it's not perfect for sauna lovers. For some reason, there is a tent set up in the relaxation space on the second floor. There is also a food and drink area (vending machines only), a co-working space, and a crane game, making it a well-equipped facility. It has everything you need, but everything feels a bit half-baked. It's not the kind of place you'd want to stay for long. At 750 yen on weekdays and 850 yen on holidays, it's reasonably priced, making it perfect for a quick bath.

A relatively new bathing facility. Perhaps because there's a gym attached, just using the bath feels cheap. It costs less than 1,000 yen. The parking lot is spacious, as it's a commercial facility. The bath itself was bustling on a Saturday evening. Because the price is low, user literacy is low. The clear water in the various baths is noticeably cloudy, making it hard to get in. The sauna can fit just over 10 people and is in good condition, but user literacy is low. I feel there's a lack of consideration for others. I won't be visiting again.

Decent public bath with gym, and friendly staff, many users are local factory workers who come in covered in grime and often skip showering before entering the bath. I raised this with management, but they admitted they couldn’t do much. I even developed foot fungus while using the facility, which led me to cancel my membership. If hygiene rules were respected, it could be a great place but as it stands, you might feel like you need another bath afterward.
