By 1970s, the need for the railway had been increasing as the development of Chiba Ichihara New Town was in progress along the planned route. The plan was changed to make connection with the Keisei Chiba Line at Chiba-Chūō Station. Construction of the line began in August 1977 for the section between Chiba-Chūō Station and Chiharadai Station (10.91 km).

Chiba Kyūkō opened the new line between Chiba-Chūō Station and Ōmoridai Station (4.2 km) on April 1, 1992. The line to Chiharadai Station was completed on April 1, 1995.

Due to a bad financial condition, Chiba Kyūkō was dissolved and the railway was sold to Keisei Electric Railway on October 1, 1998. Keisei named it "Chihara Line".
