• Hokuhoku Line: Mushigawa-Ōsugi ⇄ Matsudai

Hokuhoku-Ōshima Station opened on 22 March 1997 with the inauguration of the Hokuetsu Express Hokuhoku Line. The station is sited 38.6 km from the line's southern terminus at Muikamachi, on an elevated single side platform bridging the gap between two tunnel portals, with its station building beneath. It is unstaffed, and was provisionally named 'Kubiki-Ōshima' during construction before being renamed to combine the line name with the former village of Ōshima (now part of Jōetsu). Although the line's original planning called for a passing loop here, the loop was deleted when the third-sector operator restarted construction, which is why the Nabetateyama tunnel portal next to the station has a widened cross-section.

The widened cross-section at the mouth of the adjacent Nabetateyama tunnel is a relic of the cancelled plan to put a passing loop inside the tunnel itself.
