Our chosen hotel was the Airport Rest House, which is a 10 minute walk from Terminal 1. Views were visible from the rooms we had asked for, but given the opening hours and views to be had from the Observation Deck, you don’t need to rely on room views to do well at Narita. Rooms with views South towards Terminal 1 were 602, 604, 606, 608, 610, 612, 614, 616, 618, 620, 622, 624 & 626 – 626 is by a end of corridor window. Floors 7 & 8 were the same layout.
