[4] The station consists of a side platform serving a single track.

The station building is a timber structure and is unstaffed, housing only a waiting area, an automatic ticket vending machine and a SUGOCA card reader.

In the past, the platform track was on a siding and trains stopping at the station used to have to perform a switchback manoeuvre to enter and leave.

[3][2] Japanese National Railways (JNR) opened the station as Hongawachi Signal Box (本川内信号場, Hongawachi-shingōba) on 1 October 1943 on the existing track of the Nagasaki Main Line.

With the privatization of JNR on 1 April 1987, control of the station passed to JR Kyushu.
