History
Umijiri Station opened on 27 December 1932 as a passenger stop on what was then the Ministry of Railways' Koumi Line, in the village of Minamimaki, Minamisaku District, Nagano Prefecture. The line was completed through to Kobuchizawa in November 1935, after which the station's ticketing scope was progressively widened to cover the Chūō Main Line and beyond. With the privatisation of Japanese National Railways on 1 April 1987 the station passed to JR East. It sits at 1,034.8 metres above sea level, the eighth-highest JR station in Japan, and today consists of a single side platform served by one unstaffed bi-directional track.
