Having just experienced my first helicopter ride in Maui a few months ago, I was thrilled to get a bird's eye view of Tokyo.
Excel Helicopter Cruising offers both day and evening rides and while I would have preferred an evening outing, I found the day excursion really memorable. There also two different routes and we took the shorter of the two.
Although this is an expensive way to tour Tokyo, I recommend splurging on the longer tour because you see much more of the city. I also suggest bringing along ear plugs because the helicopter is pretty noisy even from your seat.
