Isahaya Station opened on 27 November 1898 as an intermediate stop on the Kyushu Railway's newly through-connected Tosu - Nagasaki line. The Kyushu Railway was nationalised on 1 July 1907, and the line through Isahaya was officially designated the Nagasaki Main Line on 12 October 1909. The Shimabara Railway opened its line from Isahaya to Hon-Isahaya on 21 August 1911. Route changes on 1 December 1934 routed the Nagasaki Main Line via the Ariake coast and separated Haiki - Isahaya as the Ōmura Line. Operation passed to JR Kyushu on 1 April 1987, SUGOCA arrived on 1 December 2012, the elevated bridge-over station building opened on 4 August 2018, and the Nishi-Kyushu Shinkansen reached Isahaya on 23 September 2022.

The Nishi-Kyushu Shinkansen platforms at Isahaya are built nearly at grade rather than on an elevated viaduct, making the stop one of only a handful of ground-level Shinkansen stations in the country.
