This was the mens and there was another for womens. you wouldn't go in with a bathing suit, just a small towel. this was at our final hotel. this was way out in the rural area, but sure enough when we went in there were 3 yakuza chillin there. we still went in the hot spring, just didn't want to piss them off. they were pretty cool. said excuse me in japanese because my friend david was standing infront of their clothes basket. people in japan make them out like they are cold blooded murders or something.
