The fortified residence (Inohana Castle) of the
Chiba clan was located in the area of present-day Chūō Ward during the
Kamakura period. The area was controlled by the
Satomi clan during the
Sengoku period, and was mostly
tenryo territory ruled directly by the
Tokugawa shogunate during the
Edo period. After the
Meiji Restoration, the area of present-day Chūō Ward was divided on April 1, 1889, into the town of Chiba and villages of Soga, Miyako, Chishiro, and Oihama within Chiba District. Soga was raised to town status on May 23, 1890, and Chiba Town became Chiba City on January 1, 1921. On November 10, 1928, Oihama was raised to town status. The city of Chiba annexed Soga and Miyako on February 11, 1937, followed by Chishiro on February 11, 1944, and Oihama on February 11, 1955. With the promotion of Chiba to a
designated city with additional autonomy from Chiba prefecture and the central government on April 1, 1992, the city was divided into six wards, with the central ward designed Chūō Ward. ==Economy==
