The chart shows the distance travelled by hitch hiking in Japan from 2005 to 2012.
The final trip of the year was to Tokyo on December 26, an unusually cold day with icy streets. It took twice as long as normal to get to the Sakae Parking area on the Hokuriku Expressway, and 3 hours to catch the next ride! I was about to quit when an elementary school teacher from Murakami city came and rescued me.
As you can see, year 2012, was slightly lower than 2010. The distances are in kilometers.
