Keiyō Industrial Zone

Geography

The Keiyō Industrial Zone spans the coast of Tokyo Bay from Urayasu in the northeast, through Funabashi, Chiba City, Kisarazu, Kimitsu, Ichihara, Sodegaura, and ends in Futtsu to the southeast. Numerous small rivers empty into the industrial region, and provide a source of water to support industry. They include the Edo River, the Yōrō River, and the Koito River.

History

Before industrialization the Keiyō region was originally home to nori seaweed collection, the shellfish industry, mixed small-scale fishing and agricultural villages, and beach resorts. The Keihin region, spanning west from Tokyo to Yokohama, was developed after World War I. With the rapid development of the defense industry in Japan from the beginning of the Shōwa period in 1926, a plan for the decentralization of industry from the immediate Tokyo area was planned in 1935. The Keiyō Industrial Region was fully developed after World War II. Some land reclamation had been carried out in coastal areas of Tokyo Bay as part of the industrialization of Japan in the early 20th century. Reclaimed land areas replaced traditional fishing areas and supported small factories. The construction of the Kawasaki Steel Works in Chiba City in 1953 marked the beginning of the large-scale construction of heavy industry infrastructure in the industrial zone, and other industries soon followed. The deepwater ports of the Keiyō Industrial Zone were built starting in the 1950s. Thermal power generators were built, and large tracts of land were reclaimed from the bay for expansion of the Keiyō region. Keiyō was significantly expanded in the 1960s. Heavy metal and chemical production were among the highest in Japan by the 1970s.

Industries

The zone is a major base for the electric power generation, petrochemical, petroleum, shipbuilding, logistics, shipping, and steel industries. The Port of Chiba is a major component to the Keiyō Industrial Region.
