Japan is an island nation located in eastern Asia in the Pacific Ocean to the east of China, Russia, North Korea and South Korea. It is an archipelago that is made up of over 6,500 islands, the largest of which are Honshu, Hokkaido, Kyushu and Shikoku.

Japan is one of the world's largest countries by population and it has one of the world's largest economies.

On March 11, 2011, Japan was struck by a magnitude 9.0 earthquake that was centered in the ocean 80 miles (130 km) east of the city of Sendai. The earthquake was so large that it caused a massive tsunami that devastated much of Japan. The earthquake also caused smaller tsunamis to hit areas across much of the Pacific Ocean, including Hawaii and the west coast of the United States. In addition, the earthquake and tsunami caused damaged Japan's Fukushima Daiichi nuclear power plant. Thousands were killed in Japan in the disasters, thousands were displaced and entire towns were leveled by the earthquake and/or tsunami. Additionally the earthquake was so powerful that early reports are saying that it caused the main island of Japan to move eight feet (2.4 m) and that it shifted the Earth's axis.

The earthquake is also considered to have been one of the five strongest to have struck since 1900.

History of Japan

According to Japanese legend Japan was founded in 600 B.C.E by the Emperor Jimmu. Japan's first contact with the west was recorded in 1542 when a Portuguese ship bound for China landed on Japan instead.

As a result, traders from Portugal, the Netherlands, England and Spain all began to go to Japan shortly thereafter as did several different missionaries. In the 17th century however, Japan's shogun (a military leader) determined that these foreign visitors were a military conquest and all contact with foreign countries was barred for about 200 years.

In 1854, the Convention of Kanagawa opened Japan up to relations with the west, causing the shogun to resign which led to the restoration of Japan's emperor as well as the adoption of new, western influenced traditions. According to the U.S. Department of State, in the late 19th century Japan's leaders began to view the Korean Peninsula as a threat and from 1894 to 1895 it was involved in a war over Korea with China and from 1904 to 1905 it fought a similar war with Russia. In 1910, Japan annexed Korea.

With the beginning of World War I, Japan began to influence much of Asia which allowed it to quickly grow and expand its Pacific territories. Shortly thereafter it joined the League of Nations and in 1931, Japan invaded Manchuria. Two years later in 1933, Japan left the League of Nations and in 1937 it invaded China and became a part of the Axis powers during World War II.

On December 7, 1941 Japan attacked Pearl Harbor, Hawaii which led to the United States entering WWII and the subsequent atomic bombings of Hiroshima and Nagasaki in 1945. On September 2, 1945 Japan surrendered to the U.S. which ended WWII.

As a result of the war, Japan lost its overseas territories, including Korea, and Manchuria went back to China. In addition the country fell under the control of the Allies with the goal of making it a democratic self-governing nation. It thus underwent many reforms and in 1947 its constitution went into effect and in 1951 Japan and the Allies signed the Treaty of Peace. On April 28, 1952 Japan gained full independence.
