The hotel is intended for couples, which may be a unique type of hotel in Japan. The normal procedure for walk-in customers is to select the room yourself on the vending machine in the lobby, collect the key, and then pay for the room using the payment machine in the room (basically self-service throughout). However, as foreign customers who pre-booked our stay, we still needed to fill out a form at the reception and have our passports copied (this is a requirement by the Japanese government). As it’s an adult-only hotel, it’s very discreet in order to protect customers’ privacy. E.g. you can cover your car registration plate using the board provided in the car park (free private parking outside reception). The staff are not always visible, as probably some customers would rather not be seen, but you can always ring the bell for service. The room itself is very spacious and has a few luxuries you wouldn’t normally find in Japanese hotels of the same price range. E.g., there’s a massage chair, king-size bed, fruit machine, variety of toiletries, TV in the bathroom, vibrator, condoms, etc. Most Japanese hotel rooms are tiny, but this is huge. This is the perfect hotel for couples who arrive by car, very good value. We didn't explore the local area around the hotel, so can't comment on this part.
