The actual flying time from Itami to Haneda is less than an hour. The landing approach was via Tokyo Bay onto runway 34L. Along the landing path, we were able to see the Tokyo Bay Aqua-Line Expressway which has a length of it running under the Tokyo Bay. By chance, our plane flew within sight of the Aqua-Line ventilation tower for ventilating the Expressway. The ventilating tower is sort of on a man made island in the middle of Tokyo Bay and looks like the sail of a ship.
Haneda airport is way larger than Itami as it’s the forth busiest airport in the world (2017) even beating it’s sister airport Narita (49th). After claiming our checked baggage, we took the monorail at the airport to Hamamatsucho station for a change to the Yamanote Line for our hotel in Akihabara. The ride on the monorail was 24 minutes while on the Yamanote Line was 11 minutes. The change of train line at Hamamatsucho station entails a couple of minutes walk and the use of escalator to get down to the platform. Ticket payments for the monorail and the train was made using the Icoca card we’ve purchased at Kansai airport. Yes, the Icoca can be used in Tokyo as well, in-fact for most of Japan.
