During the late 1950s and the 1960s, Japan experienced a period of high economic growth. Although metropolitan urban core areas were increasingly concentrated, disorderly urban sprawl continued to expand, which became a problem for the country. A series of Newtowns (orderly planned cities) were developed to solve this problem. The Kohoku Newtown is famous in the Kanto region. Although construction began on the Kohoku Newtown in 1974, its public transit was limited to bus service until 1993, when the subway opened. Based on this history, this study analyzed the influences of the subway on land-use changes.
