9h ninhours hotel narita, designed by Fumie Shibata is a new capsule hotel that will open on July 20th and is accepting reservations on their site. Adjacent to Narita International Airport Terminal 2, the capsule hotel has a total of 129 rooms with separate male and female quarters with a smoke-free and complimentary WiFi common area. There are no photos yet of the Narita location, but check out the beautiful photos of their Kyoto location!
If you're traveling alone, and just need a spot to sleep overnight and get refreshed, why not stay at a capsule hotel? It's super convenient! If your not claustrophobic that is. Personally I'd like to try it out one day.
