Chiba Prefecture is a prefecture of Japan located in the Greater Tokyo Area. Its capital is Chiba City. Chiba Prefecture was established on June 15, 1873 with the merger of Kisarazu Prefecture and Inba Prefecture. Historically, the prefecture constituted three provinces of Awa, Kazusa, and Shimousa. Chiba borders Ibaraki Prefecture to the north at the Tone River, Tokyo and Saitama Prefecture to the west at the Edo River, the Pacific Ocean to the east and Tokyo Bay around its southern boundary. Most of Chiba lies on the hilly Boso Peninsula, a rice farming region: the east coast, known as the Ninety-Nine League Plain, is an especially productive area. The most populous zone, in the northwest of the prefecture, is part of the Kantō region that extends into the urban agglomeration of Tokyo and Saitama. The Kuroshio Current flows near Chiba, which keep it relatively warm in winter and cooler in summer than neighbouring Tokyo. Chiba is one of Japan's largest industrial areas, thanks to its long coastline on Tokyo Bay. After Chiba was chosen as the site for a major Kawasaki Steel factory in 1950, the prefectural government embarked on a large-scale land reclamation program that dredged up large plots of waterfront property for factories, warehouses, and docks. Chemical production, petrochemical refining, and machine production are the three main industries in Chiba today: together, they account for forty-five percent of the prefecture's exports. In recent years, the government has funded more than eighty industrial parks to bring development further inland as well.
