The Sekiyama Tunnel (Japanese: 関山トンネル) is a road tunnel on the border of Miyagi and Yamagata prefectures in Japan. As part of National Route 48, it crosses the Sekiyama Pass at a maximum altitude of 531 meters. Its name refers to two distinct tunnels, one opened in 1882 and the other in 1968. Only the new tunnel is still in operation.^[1]

On 23 July 1880, during the construction of the first tunnel, 23 people died in an accident when gunpowder being transported for construction was ignited by a cigarette.^[2]
