History
The line opened on October 15, 1925, as the Daiyūzan Railway, between Kari-Odawara Station (仮小田原駅) and Daiyūzan Station, with a track gauge of 1,067 mm (3 ft 6 in) and an overhead power supply of 600 V. The terminus of the line was moved from Kari-Odawara to Shin-Odawara Station (新小田原駅), close to the present-day Midorichō Station on April 10, 1927, and finally to Odawara Station on June 16, 1935. The Daiyūzan Line was merged with the Sunzu Line on August 23, 1941, and became part of the Izuhakone Railway from June 1, 1957. From November 25, 1976, the power rating on the line was raised from 600 volts to 1,500 volts. Automatic ticket gates were installed on all stations by 2003, and were upgraded to accept both the Suica and PASMOIC Card systems by March 2007.
