The station is served by the Asa Line and is located 34.7 km from the beginning of the line at Gomen.[3] All Asa Line trains, rapid and local, stop at the station except for those which start or end their trips at Aki.[4]
Layout
The station consists of two opposed side platforms serving two tracks on an embankment. There is no station building but both platforms have shelters comprising enclosed and open compartments. A separate waiting room and bicycle shed, both built of timber, have been set up near the station entrance. From the access road, a low flight of steps leads to the base of the embankment where there is a flight of steps which leads to one platform. Going through an underpass, there is another flight of steps to the other platform.[2][3][5]
Each station on the Asa Line features a cartoon mascot character designed by Takashi Yanase, a local cartoonist from Kōchi Prefecture. The mascot for Shimoyama Station is a girl in a blue kimono with a white bird on her head. Her name is Shimoyama Chidori-chan (しもやま ちどりちゃん) and is inspired by the children's song Hama Chidori (浜千鳥) (Plovers on the Beach) written by local composer Ryūtarō Hirota. There is a monument to him at nearby Cape Oyama.[6]
