Tokyo, Japan

When foreigners go to Japan, Tokyo tops their list of places to see. Seven of the 10 most-visited destinations in the country are in the capital, according to the Japan National Tourist Organization. This makes it easy for visitors to check the top spots off their must-see lists without leaving Tokyo, a sprawling city encompassing nearly every important aspect of Japanese life (except nature; "man-made" is the buzzword here). To get to the other spots on the top-10 list, a quick shinkansen (bullet train) ride is all that's required, and that's an experience itself, as the trains run at speeds of about 200 miles per hour.
