Travel guide
Japan, known as Nihon or Nippon (日本) in Japanese, is an island nation in East Asia. Its insular character has allowed it to develop a unique and very intricate culture, while its closeness to other ancient East Asian cultures, in particular China, has left lasting influence. Despite belonging to a nation long at war, Japan's people have always placed emphasis on inner balance, tranquility and natural beauty. These traditional values have become increasingly important now that Japan has grown to be one of the world's most densely-populated countries, and its legendary work ethic makes life in its cities quite hectic.
