The Hōjō Line was merged into the Bōsō Line in 1929, and the Bōsō Line itself was divided into the Bōsō-East and Bōsō-West Lines on 1 April 1933. These lines were renamed on 15 July 1972, to the Sotobō Line and Uchibō Line. The station was absorbed into the JR East network upon the
privatization of the
Japan National Railways (JNR) on 1 April 1987. A new station building was completed in August 2006. ==Passenger statistics==
