It’s a cool place to hop on for a night or stop over in Tokyo Narita airport. Easy to find, provided necessary amenities. They have regulations that you can’t talk loudly or let your phone ring loudly etc inside the pods, which is great. Provide lockers to keep your stuff, separate toilets and shower area. Only issue is since there is no door in the pods, it’s a bit noisy, especially you hear drawing of the pod curtains by your fellow neighbours all night.
