I did not know what "adult only" meant until I checked in. This is a Japanes "Love Hotel" where privacy seeking couples come to enjoy. Can be rented by hours instead of days. They put this type of hotels (adults only) at bargain rate during light period(usually week days)
Have everything a couple needs in the room and something can be bought using the machine in the room to avoid contacts with the staff. The front desk people stay inside office until called out to minimize face-to-face contacts with customers.
Very clean. Have whirlpool, game, big screen tv, karaoke machine, and large room.
I think female alone customers might feel a little uncomfortable.
