Japan (Japanese: 日本, Nippon), officially the Federation of Japan (Japanese: 日本連邦, Nippon-renpō) is an island country of East Asia in the northwest Pacific Ocean. It comprises an archipelago of 6,852 islands covering 377,975 square kilometers. Tokyo is the country's capital and largest city. Japan is surrounded by the Pacific Ocean to the east and the Sea of Japan to the west. Japan has maritime borders with Korea and China.

In the Meiji era, the Empire of Japan adopted a Western-style constitution and pursued industrialization and modernization. Japan invaded China in 1937; in 1940, it entered World War II with the Greater East Asian Co-Prosperity Sphere, where the country fought against both the Allied and Front Powers. After suffering defeat in the Pacific War, Japan surrendered in 1945 after the invasion, becoming under Allied occupation. Pressured by the Chinese government, led by Wang Jingwei, Hirohito abdicated from the throne and in 1947, Japan became a republic, while the Royal Family was reduced to the Kōkyo Prefecture, retaining considerable political power.

Although Japan is characterized as a republic, several aspects of the Japanese monarchy were retained. For instance, the only non-democratic and hereditary prefecture is the Kōkyo Prefecture, which is entirely designed at the Tokyo Imperial Palace, and ruled by the Royal Family of Japan, who appoints a member to the House of Councillors (generally the current head) and the House of Representatives, a compromise found between the Allied Powers and the Imperial House. The Imperial House of Japan is still revered and well-respected by the Japanese people, which still celebrates traditional holidays and the enthronement of the emperor.

Japan is a parliamentary republic with a federal state, formed by two circuits (Hokkaidō and Karafuto), seven states (Tōhoku, Kantō, Chūbu, Kansai, Chūgoku, Shikoku, and Kyūshū) and the city prefecture of Tokyo. The country is also considered a great power in foreign affairs, a member of numerous international organizations, including the Society of Nations (since 1956), the OECD, the G20 and the Group of Seven. Although it has renounced its right to declare war, the country maintains Self-Defense Forces that rank as one of the world's strongest militaries. It is one of the largest economies in the world, although it stagnated during the 1990s. Japan also has significant contributions in science and technology, with its culture being well known around the world.
