I absolutely love onsens (Japanese hot springs). And I have always wanted to go to a ryokan (which is like a Bed and Breakfast+Dinner) with an outdoor onsen with a lover.
I convinced [my then bf S](https://www.reddit.com/user/Tokyogrrl/comments/jwi584/my_sexual_experience_with_a_japanese_american/?utm_source=share&utm_medium=ios_app&utm_name=iossmf) to spend a weekend in a well known hot spring area that is a couple of hours away from Tokyo. I booked a small but upscale ryokan with a private outdoor bath in each room. When we arrived at the inn, the owner madam in a kimono greeted us and showed us to our room. It was a spacious and modern beautiful Japanese style room with tatami floors, with pastel and neutral colors. Outside our window was a terrace and an outdoor hotspring bath (basically a hot tub built in the ground). The madam let us pick the yukatas that we like (a traditional Japanese lounger wear, kind of like a lighter fabric kimono) to wear during our stay. She explained the room amenities and left the room, stating they will come back to bring us our dinner.
