History

The Minato Railway (湊鉄道, Minato Tetsudō) was established on 18 November 1907, and the line was opened from Katsuta to Nakaminato on 25 December 1913, using steam haulage.^[1] The entire line to Ajigaura was completed on 17 July 1928.^[1] From 1 August 1944, the line was taken over by Ibaraki Kōtsū (茨城交通), becoming the Ibaraki Kōtsū Minato Line.^[1]

The Minato Line was the only railway line operated by Ibaraki Kōtsū, whose main business was bus transport. Because of its severe financial situation, Ibaraki Kōtsū decided to withdraw from railway operation. In September 2007, Ibaraki Kōtsū and the city of Hitachinaka agreed to transfer the line to a third-sector (funded jointly by local government and private sector) company, later incorporated as Hitachinaka Seaside Railway. From 1 April 2008, the line became the Hitachinaka Seaside Railway Minato Line.^[1]

From 6 April 2010, all train services became one-man operation.^[1]

The line was damaged by the 11 March 2011 Great East Japan earthquake, but the entire line was reopened for business from 23 July of the same year.^[1]

A new station which will be located near Hitachi Seaside Park is going to open and be extended Minato Line to the station in 2024.^[9][10]。
