Japan (lang: 日本 Nihon or Nippon^?, officially lang: 日本国 or Nihon-koku) is an island country in East Asia. Located in the Pacific Ocean, it lies to the east of the Sea of Japan, People's Republic of China, Korea and Russia, stretching from the Sea of Okhotsk in the north to the East China Sea and Taiwan in the south. The characters that make up Japan's name mean "sun-origin country", which is why Japan is sometimes identified as the "Land of the Rising Sun".

Japan comprises over 3,000 islands making it an archipelago. The largest islands are Honshū, Hokkaidō, Kyūshū and Shikoku, together accounting for 97% of Japan's land area. Most of the islands are mountainous, many volcanic; for example, Japan's highest peak, Mount Fuji, is a volcano. Japan has the world's tenth largest population, with about 128 million people. The Greater Tokyo Area, which includes the de facto capital city of Tokyo and several surrounding prefectures, is the largest metropolitan area in the world, with over 30 million residents.

Archaeological research indicates that people were living on the islands of Japan as early as the Upper Paleolithic period. The first written mention of Japan begins with brief appearances in Chinese history texts from the first century A.D.

Influence from the outside world followed by long periods of isolation has characterized Japan's history. Since adopting its constitution in 1947, Japan has maintained a unitary constitutional monarchy with an emperor and an elected parliament, the Diet.

A major economic power, Japan has the world's second largest economy by nominal GDP, after the United States. It is a member of the United Nations, G8, G4, OECD and APEC, with the world's fifth largest defense budget. It is also the world's fourth largest exporter and sixth largest importer. It is a developed country with high living standards (8th highest HDI) and a world leader in technology, machinery, and robotics.

Etymology

main: Names of Japan The English word Japan is an exonym. The Japanese names for Japan are Nippon (にっぽん) and Nihon (にほん). They are both written in Japanese using the kanji 日本. The Japanese name Nippon is used for most official purposes, including on Japanese money, postage stamps, and for many international sporting events. Nihon is a more casual term and the most frequently used in contemporary speech.

Both Nippon and Nihon literally mean "the sun's origin" and are often translated as the Land of the Rising Sun. This nomenclature comes from Imperial correspondence with Chinese Sui Dynasty and refers to Japan's eastward position relative to China. Before Japan had relations with China, it was known as Yamato and Hi no moto, which means "source of the sun".
