History
Araimachi Station opened on 10 January 1915 as an intermediate stop on the Tōkaidō Main Line in what is now the city of Kosai, Shizuoka Prefecture, located 272.9 kilometres from Tokyo. The surrounding section between Hamamatsu and Ōbu had been completed in September 1888, but Araimachi itself was added later to serve both passenger and freight traffic. Regular freight operations ceased on 6 April 1974, and parcel handling was discontinued in 1984. With the 1987 privatisation of Japanese National Railways the station passed to JR Central, which introduced TOICA in March 2008 and completed barrier-free upgrades in January 2010. Station numbering CA38 was assigned in March 2018, when the line was renumbered.

Notes
The station name uses the reading "Araimachi" while the surrounding place name is pronounced "Araichō" — the two share identical kanji but differ in reading, a divergence preserved since the station's opening.
