If you just need, as the hotel name says, a 9-hour stopover with the bare minimum for surviving a night in Narita, you can give it a try, provided you understand beforehand that this is a capsule hotel and go with correspondingly realistic expectations. Quick check-in, then a door on the right side goes to the female section and another one on the left goes to the male one. Toilet areas, showers, changing rooms in common. Capsule size: same as a single bed with enough height space to sit down without hitting your head against the sealing. If you have breakfast included, you get a voucher for the "Cafè de Crié" one floor above (out of the hotel) and get a minimalistic breakfast too. If this is not ok for you, you'd better go to a standard hotel (and pay the difference). Advantages of this place: low price and location within Narita Airport Terminal 2.
