Seki-guchi

No publicly available departure data for this station.

Sekiguchi Station opened on 26 December 1952 as one of several infill stops added to Japanese National Railways' Etsumi-Nan Line, 9.7 kilometres from the line's terminus at Mino-Ōta. With the line's closure-or-conversion decision under the Specified Local Lines programme, operations were transferred from JNR to the third-sector Nagaragawa Railway on 11 December 1986. The station has a single ground-level side platform serving one bi-directional track and is unstaffed.

The platform shelter at Sekiguchi doubles as a Lawson convenience store, an arrangement believed to be unique among Japanese railway stations.
