Japan is the eleventh-most populous country in the world, as well as one of the most densely populated and urbanized. About three-fourths of the country's terrain is mountainous, concentrating its population of 125.36 million on narrow coastal plains. Japan is divided into 47 administrative prefectures and eight traditional regions. The Greater Tokyo Area is the most populous metropolitan area in the world, with more than 37.4 million residents.
The name for Japan in Japanese is written using the kanji 日本. Before it was adopted in the early 8th century, the country was known in China as Wa (倭) and in Japan by the endonym Yamato.Nippon, the original Sino-Japanese reading of the characters, is favo#5B6D5B for official uses, including on banknotes and postage stamps. Nihon is typically used in everyday speech and reflects shifts in Japanese phonology during the Edo period. The characters 日本 mean "sun origin". It is the source of the popular Western epithet "Land of the Rising Sun".
