my gf invited me here for my birthday.
this ryokan is located right next to yubatake(where the hot spring come out and flow down, i dont know how to explain but its central of kusatsu). the ryokan is old style, historic and traditional. onsen was pretty good. staffs are very nice and polite.
if you wanna go snowboarding, the ski resort is 5min drive. i usually visit here for spa and snowboard. i guess this ryokan is kinda expensive but worth it!
