Otai Onsen

I finally visited as a sauna fan! It's been years since I had the opportunity, but I finally made it 🙇♂️ Why am I writing this? Because I regret not having been here before 😖 Conclusion: I'll definitely be back! I really love it. As other reviews have said, the layout of the facility is quite unusual: Reception & changing room on the second floor, Go down the stairs to the first floor for the bathtub & sauna. But once I went, it made sense. I think that's what allows them to have such a spacious space. The benefits of this lead to the following: Sauna temperature: 106°C. Regulars said it's a little warmer on weekdays. 106°C isn't too intense, but it does make you sweat. Not too dry, not too humid? Is it the right balance? The cold bath is apparently 100% natural groundwater. There's no water temperature display, but it feels like it's just under 20°C. The owner also said, "I often get told, 'It would be better if the water temperature in the cold bath was a little lower.'" But the feeling of natural groundwater is still quite nice. It's also spacious and deep, something you don't often see in public baths. Perhaps that's why the water temperature isn't even a factor. It really helps to tone your muscles. Even more unusual is the waterfall in the cold bath. This is also incredibly refreshing. You should definitely try it. And what's more! It's amazing that within a 5m radius there's a sauna, cold bath, and relaxation chair. The regulars seem to have formed a kind of community, with a wide age range and incredibly friendly people. They were very friendly and chatty. Please invite me to a yakiniku party someday! 🥩 lol It was really great. I've only mentioned the sauna, but the baths are also great. The facility is really spacious overall, and you can fully enjoy what a public bath is like. I'd like to go at least once a week if possible. I'll definitely go again! (Thank you for putting up the sign too🙇♂️)

It costs 530 yen for adults, so bring your own amenities! There are three types of baths, plus a cold bath and a sauna (200 yen). The facilities are pretty old, so I guess that's why they're priced so high! I think it would be really popular if they updated the facilities.💦It's a small business, and locals are the regulars! I was thinking of staying at an internet cafe to save on hotel costs, but I found this when I was thinking of going to a public bath just for the showers! The bathroom lights and tiles are cracked, and some of the fixed showers are rusty when viewed from below. I wonder if it's better than the showers at internet cafes? ? Anyway, I would recommend it to anyone who wants to soak in a bathtub, and it seems like it's incredibly cheap if you use a coupon ticket or similar service!

Friday, January 30, 2026 Second visit! The last time, it was warm, so I didn't think much of it, but maybe it was because of the cold weather... the water pressure was too weak and the temperature was too low. 😓 Also, a friend of mine had been thinking about it since the last time... but the water smelled like rust, and even though I'm not particularly sensitive to smells, I sniffed it carefully and it certainly did! I don't think I'll be coming back in the winter. 🗓️ Monday, May 5, 2025 (Wed) First visit! The bathhouse was bigger than I expected! Since it was Children's Day, they even gave me a free 👦👧😲 I even got some orange juice!! ️ ✳️Sauna costs extra ✳️No electric bath ✳️Three different water levels: hot, normal, and lukewarm, so it was very comfortable. 👍️

It's the best!! And it's piping hot!! Well, if I had to give it a title, I'd call it something like this lol. Parking available! About 6 cars, I think. It's a decent size. The building has a modern feel. For some reason, it felt like the '80s overall. Is it retro-modern? ? The reception is on the second floor, and you descend completely naked to the bath on the first floor, and even the staircase there feels somehow stylish. It's a real '80s vibe here!! And the bath, most importantly, is hot!! I've been to a lot of public baths (I mean, 4 or 5 lol), but I thought the temperature here was super hot! Even the shower was hot!! So, if you love hot baths, this place is a must-visit. If you're in the area, definitely check it out!

The receptionist was a woman. It was my first time, so I told her it was my first time, but she didn't react much. There was a sign indicating the sauna was an extra charge, so I asked for the sauna, and she said it would be 730 yen, which I paid. The only things the woman said were the price and to return the sauna towel to the front desk. It was disappointing that she didn't explain which way to go or that there was no soap or anything inside. When I left, I saw soap and other amenities for an extra charge next to the reception desk, but I think they should at least warn first-timers about the extra charge. The bath was spacious, but I won't be going back.
