Aman Tokyo occupies the top six floors of the Otemachi Tower, and the arrival is the point: a lift opens onto a thirty-metre atrium of washi paper and dark timber, silent above the city. Rooms are the largest in Tokyo and are built around the view — the Imperial Palace gardens on one side, Mount Fuji on a clear winter morning on the other. The spa runs across two floors, and the 30-metre pool is walled in glass on both sides.
