I cannot recommend this place enough if you are looking for an affordable traditional style Ryokan style in in Kusatsu.
It's a quick 10 minute walk from the station, the room was a clean and well kept tradtional tatami room and the futons were comfortable.
The onsen downstairs was clean and HOT. Probably one of the hottest I've ever been to, but hey, that's why people come to Kusatsu right?
The staff is where this place really shined, They took great care of me and went above and beyond. I speak Japanese so that might have helped, but through my own error I made the booking on the wrong date and they were happy to change it for me at no extra charge (a great relief to me) once I arrived exhausted with suitcase in hand. During breakfast (delicious traditional Japanese food/washouku) they made sure I had everything I needed, and when I was heading out the door back to the station the owner offered me a ride in his car when he saw I was going to haul my suitcases there all by myself. Wonderful staff and a lovely experience.
