[3] All Asa Line trains, rapid and local, stop at the station except for those which start or end their trips at Aki.

A separate waiting room and bicycle shed, both built of timber, have been set up near the station entrance.

[2][3][5] Each station on the Asa Line features a cartoon mascot character designed by Takashi Yanase, a local cartoonist from Kōchi Prefecture.

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.
