Source-derived summary

The Izu Kyūkō Line (Japanese: 伊豆急行線, romanized: Izu Kyūkō-sen) is a privately owned railway line of the Izukyū Corporation in Shizuoka Prefecture, Japan.

The line approximately parallels the eastern coast of the Izu Peninsula, a tourist district noted for its numerous hot spring resorts, and golf courses, between Itō Station in Itō and Izukyū Shimoda Station in Shimoda. The line opened in 1961.

Since March 13, 2010, PASMO and Suica cards are accepted on the line.

Basic data

Track: single

Signalling: Automatic (ATS-Si, compatible with East Japan Railway Company (JR East) ATS-SN.)

History

Initial plans called for the Japanese National Railways (JNR) to build a spur line linking Atami on the Tōkaidō Main Line with Shimoda. However, funding was limited in the 1930s due to a combination of a tight fiscal policy under Prime Minister Osachi Hamaguchi during the Great Depression, and a number of technical issues.

On March 30, 1935, the initial 8.7 km section of the Itō Line linking Atami with Ajiro was opened. The second (8.3 km) section from Ajiro to Itō was opened on December 15, 1938. Both sections were electrified at 1500 VDC when opened. Further work was delayed, and then canceled due to the outbreak of World War II.

Construction south of Itō resumed when the private-sector Tokyu Corporation acquired the rights to complete the line to Shimoda and established the Izukyū Corporation to manage construction and operations of this section.

Editorial analysis

Why this record matters

“Izu Kyūkō Line” is worth following because a concise public description often conceals a longer documentary argument. Here, Kyūkō, Line and railway provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 29, 2026. The linked authority identifier is Q864265. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1961, 2010, 1935 and 1938.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
