Haneda, Terminal 3 observation deck 羽田空港 第3ターミナル 展望デッキ
Free observation deck open 24 hours, views over the runways; on clear days you can see the Skytree
The deck is on top of Terminal 3, which opened on 21 October 2010 as Haneda's international terminal (then ‘Haneda Kūkō Kokusaisen Terminal’) and was renamed ‘Terminal 3’ on 14 March 2020. It is one of the airport's two free observation decks, with no booking needed: it is used both by people in transit and by those who come specially to watch the planes.
