Tōni Station opened on 1 April 1984. During the 11 March 2011 Tōhoku earthquake and tsunami, part of the tracks on the Minami-Rias Line were swept away, thus suspending services. The line resumed operations on 3 April 2013 between Sakari and Yoshihama. Services between Yoshihama and Kamaishi resumed on 5 April 2014. Minami-Rias Line, a portion of Yamada Line, and Kita-Rias Line constitute Rias Line in 23 March 2019.[1] Accordingly, this station became an intermediate station of Rias Line.
