I just went back home to the US in December and have of course done this many times. But I got curious.. let's talk what is your best way to travel out of Japan? As in I may be booking a flight and am coming from Hiroshima prefecture, usually we do shinkansen to Shin-Osaka, then get to Itami and fly to Narita or Haneda and go. But last flight that got kinda killer and I am thinking to do shinkansen all the way in to Tokyo this time. But I know the Narita train is a pain in the rear and I am not sure about getting to Haneda.
So yeah kind of bad overly general question... What is your best way to make the hop over the ocean to wherever you have to go including domestic travel here in Japan?
