The Sakanashi Tunnel (坂梨トンネル Sakanashi Tonneru) is a tunnel on the border of Akita Prefecture and Aomori Prefecture on the Tōhoku Expressway. The tunnel crosses Sakanashi Pass of the northern Ōu Mountain Range. Its 4.27-kilometer-long (2.65 mi) northbound tunnel is the longest tunnel on the Tōhoku Expressway.[1][2] Its completion in 1986 was one of the final pieces of the 679.5 km (422.2 mi) Tōhoku Expressway from Tokyo to Aomori.
