Urban settlement
Urbanization is generally of relatively recent origin. Except for the former capital cities of Nara, Kyōto, and Kamakura, no sizable town of any significance appeared before the 16th century. Most of the provincial capitals, or koku-fu, of ancient Japan were only administrative centres that contained official residences and were not developed towns. After the latter part of the 16th century, influential temples and feudal lords began to build towns by gathering merchants and craftsmen close to their headquarters. The power of the feudal lords stabilized when they built jōka-machi (castle towns), which were located so as to command and control the main transportation routes and surrounding areas; the majority of Japan’s important cities, including Tokyo, developed from them.
Next in importance were the port towns, such as Hakata and Sakai, which experienced more vicissitudes than the castle towns. In addition, some of the religious towns eventually grew to a considerable size, as in the case of Ise and Izumo. Under the regime of the Tokugawa shogunate (1603–1867), peaceful conditions fostered nationwide pilgrimages on a scale unknown in the preceding periods, and temple and shrine towns such as Kyōto and Nara flourished.
Widespread urban growth began in the late 19th century with the development of the international ports of Kōbe, Yokohama, Niigata, Hakodate, and Nagasaki and the naval bases of Yokosuka, Kure, and Sasebo. With industrialization came the rapid growth of Japanese cities, and some of the industrial towns (e.g., Yawata, Niihama, Kawasaki, and Amagasaki) were founded in response to economic development. Most of the former castle towns, and especially those along the Pacific side of the country, have been expanded directly or indirectly by industrialization. In Hokkaido and southern Kyushu, raw materials and power resources have attracted a limited number of industrial plants, which alone are responsible for the existence of cities such as Tomakomai, Muroran, Nobeoka, and Minamata.
Japanese cities are jumbled mixtures of old and new, East and West. Mixed land use, including agricultural activity, can be found side by side with the most modernized business centres and industrial establishments, and the fragmented, patchwork pattern of landownership is a formidable obstacle in ever-expanding cities of skyscrapers, subways, and underground plazas. Other serious problems are the shortage of better housing, the increasing use of the automobile, overcrowded public transportation systems, the shortage of open space for recreation, environmental pollution, and the constant menace of earthquakes and floods.
