The Mito Line (水戸線, Mito-sen) is a railway line connecting Oyama Station in Tochigi Prefecture and Tomobe Station in Ibaraki Prefecture, Japan. The line is 50.2 km (31.2 mi) long and is owned and operated by the East Japan Railway Company (JR East).
Joban Line E501 series and E531 series ten car sets continue on to Iwaki, Fukushima while the 5 car sets go to Oyama. They separate at Tomobe.
Services are often run as one-man trains.
The Mito Railway Co. opened the line on 16 January 1889[3] operating between Oyama and Mito Stations. On 1 March 1892, the Mito Railway Co. merged with the Nippon Railway.
On 1 July 1895, the Joban Line was opened by the Nippon Railway, joining the Mito Line at Tomobe Station. The company was nationalised in 1906.[citation needed]
On 12 October 1909, the Japanese Government Railways renamed the Tomobe to Mito section as part of the Joban Line, resulting in the current "Mito Line" being the section between Oyama and Tomobe.[citation needed]
The line was completely electrified on 1 February 1967.[citation needed]
