Chayamachi Station opened on 12 June 1910 with the inauguration of the Uno Line. In November 1913 the Shimotsui Light Railway began operating its own platforms here, sharing the site with the national railway from 1926. Freight handling ended in April 1970, the Shimotsui Electric Railway section between Chayamachi and Kojima was abandoned in April 1972, and parcel handling stopped in March 1985. JR West inherited the station at privatisation in April 1987. The Honshi-Bisan Line opened on 20 March 1988, simultaneously raising the station onto its present elevated structure with two island platforms. ICOCA-compatible automatic ticket gates were installed on 9 July 2007 and ICOCA itself became usable on 1 September 2007; the Midori-no-Madoguchi window closed in February 2020, replaced by a "Midori no Kenbaiki Plus" ticket machine.

The platform information signs at Chayamachi Station are written in French in addition to Japanese and English.
