"love hotel" is the one of culture particular to Japan or some asian countries.
That hotel is the place a couple drops in only to make love.
Because it is reasonable and keeps privacy of users from others,
it is used widely by young and old in Japan.
At the front desk, you needn't face a receptionist.
There are some panel of a picture which shows the interior of a room.
You choose one among those.
And you decide between REST and STAY.
REST is possible for you to make use of the room for 2-3 hours.
STAY is from night to next morning.
