In Japan, rabu hoteru/love hotels are far more than one might imagine from an American perspective. Here you might think of a Motel 6 at best, or something incredibly creepy in some horrible neighborhood. In Japan, love hotels run the gamut from swanky to minimal, but all offer privacy (some have automated payment at the room door). Many are themed or have themed rooms (tropical, Valentine, etc.). Interestingly enough, their largest demographic is married couples--and yes, married-to-each-other. Privacy, not to mention free time, is very rare in many Japanese homes, so this is the best way to go about it. Comfortable and scrupulously clean even if they are by the hour, love hotels are really a pretty good idea.
