Looking for a ryokan with a great public open-air Onsen/bath in Kyoto

Hi, I'm looking for a ryokan in Kyoto with a great public open-air onsen/bath.

I really want an experience in an open-air bath, while looking at nature/garden. I also need the accommodation to have futons to sleep in, no western beds.

Can you please give me recommendations, it can be costly. I am staying for only 1 night, I am also a solo traveller
