Where the Mountain Line Meets the Post Town

The Yunoo Tunnel sits at the northern end of the former Hokuriku Line's mountain section, in the Yunoo district of Minami-Echizen Town, about 1.6 kilometres north of Imajo Station on the current railway. For travellers coming down off the Yamanaka summit, it is among the last bores before the country opens toward Imajo, the old post town that once served as the base for the banker locomotives working the pass. This position, close to a lively junction town, gives the tunnel its own character among the more remote bores to the south.

A Portal Built to Impress

The tunnel runs about 368 metres on a gentle curve and is built of brick, but the eye goes first to its portals. Both the north and south mouths are faced in cut andesite finished by the fine Edo-kiri chiselling. The north portal is the grander of the two: its parapet extends far to left and right, and four pilasters stand across its face, giving it a broad, formal, welcoming presence. It reads less like a plain utilitarian mouth than like a proper gateway, fitting for the end of a hard mountain crossing.

Value and Visiting

Owned by Minami-Echizen Town, the Yunoo Tunnel was registered as a Tangible Cultural Property in 2016 with the rest of the line. Its northern setting makes it a natural start or finish point for a visit, easily paired with the preserved streets of Imajo-juku nearby, where a renovated station building now houses displays on the area's railway past.

The tunnel lies on the road that follows the old alignment. As elsewhere on the route, obey any traffic signals, use headlights, and check current conditions with the Minami-Echizen or Imajo tourism offices, since repairs and winter snow can close sections.
