The station consists of a side platform and two island platforms serving five tracks.
Track/platform 0 is a dead-end siding which juts into the platform 1 (the side platform) and is used exclusively by the trains of the Shimabara Railway Line.
Platform 2 is a second side platform serving track 2 while tracks 3 and 4 are served by the island platform.
Since 18 June 2016, Isahaya has operated out of a temporary station building while the construction of a new station building is in progress.
The temporary building houses a JR Kyushu ticket counter with a (Midori no Madoguchi) facility as well as a Shimabara Railway ticket window.
From the station building there is direct access to platform 0 while access to the other platforms is by means of an underpass which is served by steps and elevators.
