Totsuka Station in Meiji or Taishō period

Totsuka Station, circa 1934

Totsuka Station was opened on July 11, 1887, as a station on the Japanese Government Railways (JGR), the predecessor to the post-war Japanese National Railways (JNR).[1] The station building was originally on the west side of the station. The east gate was added in 1937.[2] The current building over the tracks was completed on March 26, 1969.[3]

On March 15, 1930, when Yokosuka Line trains were replaced by electric multiple units, all Tokaido Line trains ceased to stop at Totsuka Station.[4] Before the Tokaido Line and Yokosuka Line were separated and the station became a junction of the two lines on October 1, 1980, the two lines used the same tracks, but only Yokosuka Line trains stopped at Totsuka Station. The current platforms 1 and 2 did not exist, and the platform 1 (now platform 3) served the Tokyo-bound Yokosuka Line, while line 2 (now line 4) served the away-from-Tokyo direction. Additionally, the current freight lines did not exist, with the old freight lines located where the current platforms 1 and 2 are. From March 1973 when one island platform was added, there were two island platforms, with platform 2 serving the Tokyo-bound trains, and platform 3 serving the other direction.[3] The lines on platforms 1 and 4 were built, but were not used until 1980.

Originally, the station handled both passengers and freight. In 1923, a separate freight yard was completed as a part of the station to the north of the passenger platforms across the crossing with Tōkaidō Highway.[5] All freight operations were discontinued from May 1970.[1] As the addition of the new freight lines claimed the land of the bus terminal in front of the station's west gate, the bus terminal was relocated to the site of the former freight yard in July 1971.[6] The bus terminal is now called the Second Bus Center and is distinguished from the larger Bus Center beside the Totsukana building on the same side of the station.

With the privatization of the JNR on April 1, 1987, the station came under the operational control of JR East.[1] Shōnan-Shinjuku Line trains and Narita Express limited express services began stopping at Totsuka Station from December 1, 2001.

The timetable was revised on March 18, 2007, so that Tokaido Line Acty rapid trains all stopped at this station. This resolved the confusing situation that existed before, when the Shonan-Shinjuku Line rapid and special rapid trains stopped at the station, but Tokaido Line Acty services did not. Before the change, it was also the only station for changing trains at which the Acty did not stop. As before, the Tokaido Line commuter rapid still do not stop at this station.

The Blue Line of the Yokohama Subway connected to Totsuka Station from May 24, 1987, with temporary facilities. The permanent subway station was opened on August 27, 1989.[7]
