History
The station opened on 28 April 1929 as Tsubojiri Signal Box when the line was extended from Sanuki-Saida to Tsukuda Signal Box (now Tsukuda), thereby linking up with the Tokushima Line. It was operated by Japanese Government Railways and later Japanese National Railways. The signal box was upgraded to a passenger station on 1 October 1950. With the privatisation of JNR on 1 April 1987 it passed to JR Shikoku. The station sits in a deep ravine on the Ayukutani river with no access road; passengers must descend a 600 m mountain footpath from Tokushima Prefectural Route 5. A switchback manoeuvre is required for trains to call there, and only three trains per direction stop each day.

Notes
An eki stamp placed in the waiting room in 2008 disappeared on 10 February 2010 and turned up two months later at Nakasawa Station on the Tsugaru Line in Aomori, about 1,300 km away; a map of its round-trip was posted in the waiting room after its return.
