• Tosaden Kotsu Ino Line: Miyano-oku ⇄ Ujidanchi-mae

Kōnai Station opened on 16 September 1907 when Tosa Electric Railway extended the Ino Line west from Kagamigawabashi as far as here. The Kōnai-zaka pass beyond the stop was too steep for the new line, so the operator first opened the section past the pass (Edagawa–Ino) and then completed the Kōnai–Edagawa section through the pass on 20 February 1908 — only then was the line through to Ino. To avoid the steep gradient, the original track route ran under the Dosan Line bridge from the stop, then under the parallel highway through a tunnel that was both narrow and curved — too tight for bogie cars, which made the pass the bottleneck of the line. The tunnel was demolished on 30 September 1960, when a three-kilometre stretch of road and track spanning the pass was rebuilt and the track moved to a new alignment running along the north side of the road. The stop passed to Tosaden Kōtsū on 1 October 2014 with the operator merger. The 892 m gap between Kōnai and Ujidanchi-mae is the longest stop-to-stop distance on Tosaden Kōtsū.

Kōnai sits on Kōnai-zaka, the pass that marks the boundary between Kōchi City and Ino, with the summit of the pass just west of the stop. From 1908 until 1960 the Ino Line crossed the pass through a narrow, curved single-track tunnel under the parallel road — too tight for bogie cars, and the worst bottleneck on the line — until the tunnel was demolished in September 1960 and the track realigned alongside the road.
