• Dosan Line: Minawa ⇄ Awakawaguchi

Iyaguchi Station, in the Yamashiro district of Miyoshi, Tokushima Prefecture, opened on 28 November 1935 when the then-Kōchi Line was extended north from Toyonaga to Minawa and the route was renamed the Dosan Line. The station became unstaffed (under simple commission) on 1 October 1970, with parcel handling simultaneously restricted to specially handled newspapers; small-lot freight had ceased on 1 June. JNR privatisation on 1 April 1987 transferred operations to JR Shikoku, and the simple commission for ticket sales had been lifted by March 2017. The earlier station building was demolished after the JR handover and replaced by a log-cabin-style waiting room. The single-platform halt carries the station number D24.

The original station building was demolished after JR Shikoku took over in 1987; today's log-cabin-style waiting room stands on the same site and was put up, before the towns merged into Miyoshi City, at the request of local residents and funded by the former towns of Ikeda and Yamashiro.
