Geography
Japan has a total of 6,852 islands extending along the Pacific coast of Asia. The country, including all of the islands it controls, lies between latitudes 24° and 46°N, and longitudes 122° and 146°E. The main islands, from north to south, are Hokkaido, Honshū, Shikoku and Kyūshū. The Ryukyu Islands, including Okinawa, are a chain of islands south of Kyushū. Together they are often known as the Japanese Archipelago.
About 70 to 80 percent of Japan is forested, mountainous, and unsuitable for agricultural, industrial, or residential use. This is because of the generally steep elevations, climate and risk of landslides caused by earthquakes, soft ground and heavy rain. As a result, the habitable zones, mainly located in coastal areas, have extremely high population densities. Japan is one of the most densely populated countries in the world.
