16. Japan

The Japanese are similar travelers to #2 on our list in terms of travel habits. Coming from a country with a rich history (and possibly due in part to its history of isolationism), the Japanese much prefer to travel within the country than abroad. Though each person generally takes 2.3 trips per year, 2.2 of those are within the country. With volcanoes, mountains, beaches, and massive metropolises, Japan has plenty for its citizens to visit.
