Housing in Japan includes modern and traditional styles. Two patterns of residences are predominant in contemporary Japan: the single-family detached house and the multiple-unit building, either owned by an individual or corporation and rented as apartments to tenants, or owned by occupants. Additional kinds of housing, especially for unmarried people, include boarding houses (which are popular among college students), dormitories (common in companies), and barracks (for members of the Self-Defense Forces, police and some other public employees).

An unusual feature of Japanese housing is that houses are presumed to have a limited lifespan, and are generally torn down and rebuilt after a few decades, generally twenty years for wooden buildings and thirty years for concrete buildings – see regulations for details.

Figures from the 2003 Housing and Land Survey conducted by the Ministry of Internal Affairs and Communications indicate that Japan had 53,890,900 housing units at the time. Of these, 46,862,900 (86.9%) were occupied and 7,027,900 (13.0%) unoccupied. Of the occupied units, 28,665,900 (61.2%) were owned by the resident household. The average number of rooms per unit of housing was 4.77, the average total floor area in was 94.85 square meters (28.69 tsubo; 1,021.0 sq ft) and the average number of people per room was 0.56. 45,258,000 units (96.6%) were used exclusively for living and 1,605,000 units (3.4%) were used both for living and commercial purposes. Of the units used exclusively for living, 10,893,000 (24.1%) were equipped with an automatic smoke detector. As of 2003, 17,180,000 housing units (36.7%) are classified by the Japan Ministry of Internal Affairs and Communication as being located in urban areas while 27,553,000 housing units (58.8%) are located in rural areas.

Japan ⁱ/dʒəˈpæn/ (Japanese: 日本 Nihon or Nippon; formally 日本国  Nippon-koku or Nihon-koku, literally the State of Japan) is an island nation in East Asia. Located in the Pacific Ocean, it lies to the east of the Sea of Japan, China, North Korea, South 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", which is why Japan is sometimes referred to as the "Land of the Rising Sun".

Japan is an archipelago of 6,852 islands. The four largest islands are Honshū, Hokkaidō, Kyūshū and Shikoku, together accounting for ninety-seven percent of Japan's land area. Japan has the world's tenth-largest population, with over 127 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 lived in Japan as early as the Upper Paleolithic period. The first written mention of Japan is in Chinese history texts from the 1st century AD. Influence from other nations followed by long periods of isolation has characterized Japan's history. In the late 19th and early 20th centuries, victory in the First Sino-Japanese War, the Russo-Japanese War and World War I allowed Japan to expand its empire during a period of increasing militarism. The Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the atomic bombings of Hiroshima and Nagasaki. Since adopting its revised constitution in 1947, Japan has maintained a unitary constitutional monarchy with an emperor and an elected parliament called the Diet.
