km section of the Itō Line linking Atami with was opened. The second (8.3 km) section from Ajiro to was opened on December 15, 1938. Both sections were electrified at 1,500 V DC when opened. Further work was delayed, and then canceled due to the outbreak of World War II. CTC signalling was commissioned in 1958, and the Atami to Kinomiya section was duplicated in 1968. The entire line was originally designed to be built as double track, and earthworks were undertaken on this basis, including tunneling, but to date only the first 1.2 km of the line has been duplicated. Construction south of Itō resumed in 1961, when the private-sector Tokyu Corporation acquired the rights to complete the line to Shimoda and established the Izukyu Corporation to manage construction and operations of this section.
