My girlfriend and I are going to Kusatsu Onsen this fall. I heard that some onsens have a spa pass or a “onsen tegata” which you can use to visit multiple facilities. Does Kusatsu have something like this?

They have what's called a “Santo Meguri Tegata” in Japanese with which you can go to the following three hot springs; Gozanoyu, Ohtakinoyu, and Nishino Kawaranoyu. It's 500 yen cheaper than going to them individually.
