Makoto no yu - An indoor hot spring in Kyoto, Kansai

This onsen is clean and efficiently run. You first remove your shoes and put them in a locker (free of charge) at the entrance. Then you pay for what you want (onsen, massage, towels etc) at a vending machine which will give you a ticket. Hand the ticket to the person on the front desk and give them your shoes locker key. He/she will then give you a clothes locker key in exchange. Go to the 3rd floor where the changing rooms are. The main onsen baths are on the same floor, but if you go upstairs there is an outside section and a sauna (with TV usually showing a local baseball game). This is a very pleasant onsen and only costs ¥1000 for an unlimited time. Don't worry if you forgot your towel, you can rent one for ¥250. Note that (like most onsens) people with tattoos are not allowed in there is also a security camera in the changing area, which seemed a little invasive (there was in the men's anyway).

Good hot pool and jet area. 2 hot pools main floor, second floor has 1 outdoors hot pool, 1 indoor cold pool and sauna. Tattoos not allowed. Very nice lady at the front desk, very kind. Would like all the pools on the same floor though. A bit expensive (¥1.000). Free parking

You need to pay first in a vending machine and then you are getting a key. Baths are separate for women and men. There’s 3 hot pools and sauna. One of the pools is on the roof so you can chill and look at the sky.
