As others said, it depends on where in Asia you want to go and what's available to book. In regards to Tokyo, I find navigating has become much easier in the last few years. I've been to Tokyo several times since 2003. All train ticket machines now have English as an option and once you got the gist of paying which fare and how the network has different train operators, it's not so bad and inexpensive. More people seem to speak a little English now. If you stay near Hamamatsucho station, you can easily catch the monorail to Haneda for about 500 yen. Narita is far away from central Tokyo, it's a lovely little town, with reasonable hotels, but there isn't much to do there once you've seen the shrine.
