Are you keeping up with your Japanese? :). Have you installed Anki and a vocab deck yet? :) A really easy way to make the best gains without much effort is just doing your Anki each day. Get a Core 2k or Tango n5/n4 deck, set it at 5-10 words a day, and just do the reviews as your taking a dump, walking to the store, waiting in line, etc.
