The line connects Matsuyama with Tōon in Ehime Prefecture, Japan.

Iyotetsu attempted to close the section between Hirai and Yokogawara and convert it into a bus line in 1965, when the Morimatsu line branching off from Iyo-Tachibana was closed due to deficits and lack of passengers.

The passing municipalities heavily opposed this attempt, and encouraged Iyotetsu to electrify the line to increase passengers.

Iyotetsu later decided to keep the section in operation and electrify the entire line.

[citation needed] The majority of rail services continue past Matsuyama City Station on the Takahama Line to Takahama Station.
