Shin-Tamana Station is served by the Kyushu Shinkansen high-speed railway line which operates between Hakata in Fukuoka Prefecture and Kagoshima-Chūō in Kagoshima Prefecture.

Shin-Tamana Station is served by Tsubame stopping services, but a small number of limited-stop direct Sakura services to and from Shin-Osaka also stop here.

The station has two opposed side platforms, serving two tracks.

From October 2015, JR Kyushu plans to remove platform operating staff from the station as a cost-cutting exercise.

This will become the first shinkansen station to operate without staff present on the platforms.
