After the
Meiji Restoration, the area of present-day Wakaba Ward was divided on April 1, 1889 into the villages of Tsuga, Miyako, Chishiro, Shirai and Sarashina within Chiba District. On February 11, 1935, Tsuga and Miyako villages were annexed by the neighboring city of Chiba, followed by Chishiro village on February 11, 1944. On March 31, 1955, Shirai and Sarashina merged to form the new town of Izumi, which was subsequently annexed by the city of Chiba on April 10, 1963. With the promotion of Chiba to a
designated city with additional autonomy from Chiba prefecture and the central government on April 1, 1992, Wakaba Ward was created as an administrative unit. ==Economy==
