For a great view of the airport, check out the Observation Deck at Central Building 5F. Be warned though - it can be cold and windy in winter. Close by are the NAA Art Gallery and SKY GATE FM, which has a glass booth so you can watch the radio DJs at work.
Head for the Tourist Info Center or the Glass Tower to join in traditional art demonstrations such as crafting an herbarium or trying origami. Kabuki Gate after Security is a must for theater fans.
Spa facilities are found on the 2nd and 5th floors at Raffine, both before Passport Control. Bookings are recommended. Spruce up at the nail bar and hair salon on the 4th and 5th floors respectively.
