I don't know who the first person was that thought to do this, but I have heard it from a couple of people. You go to Google Maps and then click on get directions. You type in USA as start of destination and Japan as the end point.
This is what what comes up. *click on image to enlarge*
Then they are nice enough to lead you to Hawaii for a break before you get to #46 in the directions which tells you to to kayak across the Pacific Ocean again until you get to Japan. You would think once you kayaked to Japan that you would just be in Japan.... but you still have 31 more directions before it says you are officially in your destination spot of Japan. From start to finish there are 78 directions.
