The Path to Development

Since the 1930s, petrochemical factories and steel factories have been built one after another in the coastal industrial area, and many people gathered from rural areas to the suburbs of Tokyo, a large city.
Yokohama, which is a distance that can be reached by train, has been built as a place for fathers working in Tokyo. As a result, the city's population surged from about 1.14 million in 1955 to about 1.79 million in 1965.

The Kohoku New Town area, located in the northwestern part of Yokohama City, used to be a rural area with gentle hill fields, bamboo forests, forests, and paddy fields spread across Tando.
However, in the 1940s, the surrounding area was converted into a residential area with "high economic growth".
The hills have been cut down, and houses were built more and more on the land created by the fields. The cityscape created in this way was somewhat similar, with the road was dead end or suddenly narrowed.
The development of such residential areas has spread more and more like cabbage green insects that eat cabbage. This movement of residential areas is called the "sprawl phenomenon" in the sense of "chaotic urbanization phenomenon".
