[1] Aka Station is served by the Tagawa and is located 18.4 km from the starting point of the line at Yukuhashi.

[2] The station consists of one side platforms serving a single bi-directional track.

The station building also houses the Akamura Chamber of Commerce and Industry.

Construction for the line, which was planned to connect to Urushio Station [ja] (now defunct), was halted due to the decrease of coal production and low projected ridership.

The town of Aka currently operates a seasonal electric train on a short segment of the track for tourism.
