History
Being land formerly underwater, Mihama had no predecessor towns or villages before the reform of the old provincial system in 1872.

Reclamation of 19 kilometers of white sand beach and mudflats along the shore of Tokyo Bay began in 1912, with the construction of Japan’s first civilian aerodrome. The site is commemorated today by the Inage Civil Aviation Commemoration Center. Following World War II, the expanding Tokyo Metropolis created a demand for additional factory locations and public housing. The development of the Kaihin New Town from 1969-1995 was one such project. With the promotion of Chiba to a designated city with additional autonomy from Chiba prefecture and the central government on April 1, 1992, Mihama Ward was created as an administrative unit.

Economy

Mihama Ward is largely a regional commercial center and bedroom community for central Chiba and Tokyo. The newly developed waterfront area of Kaihin Makuhari is in Mihama-ku.
