• Odakyu Odawara Line: Kayama ⇄ Hotaruda

Tomizu Station opened on 1 April 1927 as a stop on the Odakyu Odawara Line, initially served only by direct through services to Shinjuku. From June 1945 it joined the regular all-stations stopping pattern; it became a semi-express stop in October 1946 and a commuter semi-express stop in March 1960, the latter service being discontinued in November 1964. The station name comes from the area's abundance of water — irrigation channels fed by the Sakawa and Kari rivers, and local springs. Tomizu was dropped from the semi-express stopping pattern on 15 March 2008, when semi-expresses ceased running west of Shin-Matsuda; station numbering as OH 44 was added in January 2014.

The platform tops out at 120 metres — six 20-metre cars — so ten-car Odakyu services skip the station rather than overrun the ends.
