The Izuhakone Railway Sunzu Line (伊豆箱根鉄道駿豆線, Izuhakone Tetsudō Sunzu-sen) is a commuter railway line of the Izuhakone Railway, a private railroad in Japan. The line connects Mishima Station in the city of Mishima with Shuzenji Station in the city of Izu, both within Shizuoka Prefecture. The name "Sunzu" comes from the former provinces of Suruga and Izu, although the line at present operates only within the borders of former Izu Province.

Limited Express Odoriko

The Odoriko runs two services on weekdays and three services on holidays on the Sunzu Line. Previously using 185 series sets, E257-2000/2500 series trains were introduced by JR East in 2021. A limited express ticket is required to board the Odoriko.

History

The Sunzu Line opened for operations on May 20, 1898, connecting Zuso-Mishima Station (present-day Mishima-Tamachi Station) with Nanjō Station (present-day Izu-Nagaoka Station). The terminus of the line was moved to Mishima Station (present-day Shimo-Togari Station) on June 15, 1898, and the southern end of the line was extended to Ōhito Station on July 17, 1899.

The line became part of the Izu Railway (伊豆鉄道, Izu Tetsudō) on July 19, 1907, which in turn became the Sunzu Electric Railway (駿豆電気鉄道, Sunzu Denki Tetsudō) on April 1, 1912. This company merged with Fuji Hydroelectric (富士水電) in 1914 and was spun back out as the Sunzu Railway (駿豆鉄道, Sunzu Tetsudō) on November 5, 1917. The line was electrified by June 1919, and the southern terminus extended to Shuzenji Station on August 1, 1924. In May 1933, regularly scheduled weekend services to Tokyo Station began operation but were later suspended during World War II. With the opening of the Tanna Tunnel in 1934 and the re-routing of the Tōkaidō Main Line, the Sunzu ceased operations at Shimotogari Station and its northern terminus became the new Mishima Station. A rail yard and train factory was completed at Daiba Station on June 10, 1937.

In 1949, the Japan National Railways began semi-express and limited-express train operations from Tokyo. The Sunzu Railway Company was acquired by the Izuhakone Railway on June 1, 1957. The line was upgraded from 600 V to 1,500 V on September 7, 1959. All freight operations were discontinued as of June 16, 1972. An ATS system was installed in December 1972 and a CTC system in 1985 (upgraded in 2007).
