Japan

Japan is an island country in East Asia, located in the Pacific Ocean off the northeast coast of the Asian mainland. It is bordered on the west by the Sea of Japan and extends from the Sea of Okhotsk in the north to the East China Sea in the south. The Japanese archipelago consists of four major islands—Hokkaido, Honshu, Shikoku, and Kyushu—and thousands of smaller islands, covering around 380,000 square kilometres (150,000 sq mi). With a population of more than 125 million as of 2020, Japan is the 11th most populous country. Tokyo is its capital and largest city. Japan is divided into 47 administrative prefectures and eight traditional regions. About three-quarters of the country's terrain is mountainous and heavily forested, concentrating its agriculture and highly urbanized population along its eastern coastal plains. Greater Tokyo is the world's most populous metropolitan area, with more than 38 million inhabitants as of 2016. Part of the Pacific Ring of Fire, Japan's islands are prone to destructive earthquakes and tsunamis.
