We stayed here for one night while passing through Karatsu on a roadtrip through Northern Kyushu. Overall, the room was very clean with traditional tatami floors and an outdoor bathtub overlooking the ocean. The property was very quiet. I didn't see any other guests until the next morning at breakfast. The best part of this place was taking a hot bath and hearing the waves break outside. If we happen to be in Karatsu next time, we would definitely stay here again.
