The Sagami Railway was established in Chigasaki, Kanagawa, in January 1917, to transport gravel along the Sagami River valley. The first section, between Chigasaki and Samukawa was opened in 1919, and the line was extended gradually to Hashimoto in 1931. Sagami Railway started direct operation to Hachioji, but performance was sluggish during the economic depression, so Sagami Railway became a subsidiary of Tokyu in 1941.
