country

A country consisting of an archipelago off the eastern coast of Asia. The islands' indigenous culture was largely supplanted after c. 600 bc by settlers from the mainland, who adopted an imperial system of government modeled on China's. After a long period (12th-19th century) of domination by a series of shoguns, feudalism was abolished on the restoration of the emperor Mutsuhito (1868) and the country was opened to trade with the West. Japan's industrialization and expansionism led to a series of wars, culminating in its defeat (1945) in World War II. After the war Japan's economy was rebuilt with American assistance, developing an industrial sector centered around automobiles and electronics. Tokyo is the capital and the largest city. Word History: In ad 670, during the early part of the Chinese Tang dynasty, Japanese scholars who had studied Chinese created a new name for their country using the Chinese phrase for "origin of the sun, sunrise," because Japan is located east of China. In the Chinese of the time (called Early Middle Chinese), the phrase was ŋit-pən'. To this the scholars added the Chinese word -kwək, "country," yielding a compound ŋit-pən'-kwək, "sun-origin-country, land of the rising sun." The consonant clusters in this word could not be pronounced in Old Japanese, and it became Nip-pon-koku or *Ni-pon-koku. The Modern Japanese names for Japan, Nippon and Nihon, come from the Old Japanese forms, minus the element meaning "country." Interestingly, the Chinese took to calling Japan by the name that the Japanese had invented, and the English name Japan ultimately derives from the Chinese version. In Mandarin Chinese, one of the descendants of Middle Chinese, the phrase evolved to Rìběnguó. Marco Polo records an early form of this as Chipangu, which he would have pronounced (chĭ-pän-go͞o) or (shĭ-pän-go͞o). The Chinese name was also borrowed into Malay as Japang, and in the 16th century, Portuguese traders borrowed the Malay name as Japão. The other languages of Europe probably adopted the name from the Portuguese. The first known use of Japan in English dates from 1577, when it is spelled Giapan.

Relief

The mountainous character of the country is the outcome of orogenic (mountain-building) forces largely during Quaternary time (roughly, the past 2.6 million years), as evidenced by the frequent occurrence of violent earthquakes, volcanic activity, and signs of change in sea levels along the coast. There are no sizable structural plains and peneplains (large land areas leveled by erosion), features that usually occur in more stable regions of the Earth. The mountains are for the most part in a youthful stage of dissection in which steep slopes are incised by dense river-valley networks. Rivers are mostly torrential, and their valleys are accompanied by series of river terraces that are the result of movements in the Earth’s crust, as well as climatic and sea-level changes in Holocene times (i.e., the past 11,700 years). Recent volcanoes are juxtaposed with old and highly dissected ones. The shores are characterized by elevated and depressed features such as headlands and bays, which display an incipient stage of development.

Climate

In general, Japan’s climate is characterized as monsoonal (i.e., governed by wet and dry seasonal winds). The main influences are the country’s latitudinal extent, the surrounding oceans, and its proximity to the neighbouring Asian landmass. There are numerous local climatic variations, the result of relief features. In winter the high pressure zone over eastern Siberia and the low pressure zone over the western Pacific result in an eastward flow of cold air (the winter monsoon) from late September to late March that picks up moisture over the Sea of Japan. The winter monsoon deposits its moisture as rain or snow on the side of Japan facing the Sea of Japan and brings dry, windy weather to the Pacific side. The pressure systems are reversed during the summer, and air movements from the east and south (the summer monsoon) from mid-April to early September bring warmer temperatures and rain. Cyclonic storms and frequent and destructive typhoons (tropical cyclones) occur during late summer and early fall, especially in the southwest.

The warm waters of the Kuroshio (Japan Current), which corresponds in latitude and general directional flow to the Gulf Stream of the Atlantic, flow northward along Japan’s Pacific coast as far as latitude 35° N. The Tsushima Current branches westward from the Kuroshio off southern Kyushu and washes the coasts of Honshu and Hokkaido along the Sea of Japan; it is this current that lends moisture to the winter monsoon. The Pacific counterpart of the Atlantic’s Labrador Current, the cold Oya (Kuril) Current, flows southeastward from the Bering Sea along the east coast of Hokkaido and northeastern Honshu. Its waters meet those of the Kuroshio, causing dense sea fogs in summer, especially off Hokkaido.

The physical feature that most affects climate is the mountainous backbone of the islands. The ranges interrupt the monsoonal winds and cause the gloomy weather and heavy snows of winter along the Sea of Japan coast and the bright and windy winter weather along the Pacific. Temperatures and annual precipitation are about the same on both coasts, but they drop noticeably in the mountainous interior.
