小平天然温泉テルメ小川

Nice place I tried for first time. Like many onsen in this area, baths are not very hot (I continue to look for hotter as they are in Tohoku).

A rather small but otherwise very neat facility. Around 8 pools are accessible, both cold and hot, inside and outside. Massage services are available for purchase, and there is also a small restaurant. Plenty of parking space. Overall cozy and clean, there are more fancy establishments out there but you don't go wrong if you choose to spend your time here.

This is a community hot spring. It is very clean and has a variety of baths to try out. My favourite is the steam room. It's a great way to get toxins out of the body. Tattoos are not allowed and they are easily detected, because you are required to go into the baths naked. There is a bath on the outside which is ideal for winter time and star watching. If after your bath you're a little hungry, you can choose a bite from the restaurant or opt for ice cream. There are vending machines everywhere, even one for towels and other toiletries in the event you leave yours. You receive a bracelet that you use to scan the lockers to open and close, and you use it for purchasing food, drinks, a professional massage or 20 minutes in the massage chair. I love this place, but weekends are very busy.

It was many types of bath and also good sauna. I like it. It looks a little old, but I can recommend this place. But I can't pay by my card here, it was chipless type card what doesn't support.

The facilities have gotten a little old and the restaurant is just so-so. Also it's a bit of a trek along a busy road from the nearest stations, although there is infrequent bus service. The real draw is that the water quality is good (it's typical naturally coffee-colored in the Tokyo area) and the baths are quite spacious and less crowded than other 'super sento' because there aren't as many attractions for families and groups. The men's and women's baths switch daily between Japanese and Roman themed, and I quite like the herbal sauna in the latter.
