Japan, one of the most homogenous societies on earth, has some of the most varied landscapes imaginable. Since most of its terrain is volcanic, its people tend to be crowded into huge megalopolises. A rich rural life, a native religion, Shinto, which is closely tied to nature, and Buddhist influences from the Asian mainland all contribute to Japan's culture. It is both traditional and modern, making it one of the most fascinating and economically powerful countries in the world.
