Ichinoyu Koga

This super public bath is located between Koga and Kurihashi. There doesn't appear to be a shuttle bus, so you'll need to use your own car. Local buses are also available, and a timetable is posted. The on-site parking lot isn't particularly spacious, but I was able to use it when it was available. There's a second parking lot across the road, so it seems to have plenty of space. After leaving my shoes in the shoe locker, I purchased a ticket from the ticket machine. The bathing fee on weekends is 1,000 yen. Considering that it's not a natural hot spring, I think it's a bit pricey. Cash only. After checking in, there's a hair salon, beauty salon, and rock sauna on the right, and a restaurant on the left. The bathhouse is at the back. The indoor bath has a high-concentration carbonated spring in the center, as well as other attraction-type baths like a jet bath and electric bath. There's a dry sauna and a cold bath. There's luggage storage near the entrance and in the center. The carbonated spring is always crowded. The sauna is a tower-shaped bath with several tiers. I used the top tier, but it wasn't particularly hot. The open-air bath (apparently called "noten" here) has a circular bath in the center and a reclining bath connected to it. There's a special bath, a tub bath, and a waterfall bath and cave bath in the back. There's also a salt sauna. The special bath was a sake bath, called "celebratory sake." It didn't particularly smell like alcohol. There are stepping stones in front of the tub bath, so if you accidentally step on one, you'll fall to your waist. It's pleasant once you get used to it. I imagined the cave bath would be dome-shaped, but the ceiling was quite high and the sound of dripping water didn't reverberate. The salt sauna had benches that could seat about six people, and the salt felt quite fine. After the salt sauna, your skin felt smooth. It was a Saturday during the New Year period, and it was bustling with families, but not overly crowded. The outdoor deck chairs were being rotated at full capacity, so it wasn't overly crowded.

This super public bath is well-designed and comfortable. If it had natural hot springs and a bathing fee of less than 800 yen, it would get 5 stars. There were no major flaws. There were no malfunctions or stains in the facilities. The staff was efficient, so the indoor bath was always neatly lined with buckets and chairs, and the changing rooms were very clean and comfortable! I'd read some reviews saying the sauna was lukewarm, but I was able to sweat it out just fine. The cold bath also had a chiller, so it was a comfortable temperature. The highly concentrated carbonated spring was also large, large enough to fit 10 people. Because the water is lukewarm, it's easy to have to wait, but this rarely happens here. ...

Another nice Super Sentoh public bath centre (with no natural spa but a OK), where an artificial high-concentrated carbonate bath and a free salt sauna are the selling points (to me, at least) as well as a many free and easy resting spaces adjacent to the reasonable restaurant in it. Because of these beauties, the facility becomes very crowded at peak times like weekend afternoons, but I’m sure you can survive that since the staff and visitors are basically pretty easy and nice, probably thanks to Koga City’s regionalism.

There are rare cave baths and waterfall baths. There are many types of outdoor baths. The indoor baths are also fun with a jacuzzi and electric bath. It is also cleaned well, so you can feel safe. Rather than focusing on the quality of the hot springs, it is more of a place for entertainment, so I think it would be nice to relax if it was in my hometown☺️✨️

It’s an amazing place! Has all types of things you can find in an onsen. Outdoor, indoor, sauna, jet bath, electric current bath.. everything ! Has good relaxing space to lie down after onsen as well! 10/10 Recommend!
