Here are some Haneda Airport maps. I have been through Haneda a few times as I have traveled in and out of asia. Its one of the best, simplest and easy airports to navigate. Its modernized with PLENTY of outlets.
Normally, if I am flying withing Japan or short trips in Asia, I go through Haneda airport. If its very long International flights, I am going through Narita.
