The village of Samukawa was founded in 1889 with the establishment of the modern municipalities system. It was linked with Chigasaki Station by the Sagami Line in 1921. A spur line extending from Samukawa to the west led to development of housing and industry, increasing the population of Samukawa such that by 1940 it was granted town status. The Sagami Naval Arsenal of the Imperial Japanese Navy was located in Samukawa until the end of World War II. In 2002, a large quantity of mustard gas was found buried under its former site.
