First Cabin Haneda Terminal 1

If you're catching an early flight or arriving late at Haneda Airport, the domestic terminal is home to one of the fanciest capsule hotels we've ever seen. Just don't let the staff at First Cabin hear you using that word: they prefer to refer to their snug, high-ceilinged rooms as 'cabins' rather than capsules, coming in both 'business' and 'first class' versions (opt for the latter if you actually want to have space for your luggage). Rooms are available for overnight stays (from ¥4,900), though can also be booked during the daytime for periods of two hours or more – ideal if you're just looking to have a quick nap. Much like at a regular capsule hotel, toilets and bathing facilities are all shared.
