The station building is a modern design built of steel and glass and is an elevated structure where the passenger facilities such as the ticket window and waiting area are housed in a bridge which spans the tracks.

From the station forecourt on the south side of the tracks, there is, in addition to steps, a ramp which leads to an elevator which gives access to the facilities on the bridge.

It is also possible to enter the station bridge structure from the north side of the tracks using steps or an elevator.

It staffs the ticket window which is equipped with a POS machine but does not have a Midori no Madoguchi facility.

On 1 May 1945 the station name was changed to Hizen-Kanzaki (肥前神埼) and on 10 April 1956 back to Kanzaki (神埼) again.
