We just recently went to Japan and I put together this video to help with packing tips, getting snacks through airport security, and a few other tips.
I am a very light and efficient packer when I am traveling and I try my hardest to pack everything into a backpack. I RARELY check a bag -- once I land I just want to move on...either get to my hotel or go HOME! There is always so much chaos at the baggage carousel I just chose to pack light and it works!
Hopefully you take a few of these tips and implement them on your next trip!
