The railway of Tohoku Shinkansen between Hachinohe Station and Shin-Aomori Station (81.2km) is now under construction, with completion aimed for 2010. Along the length of the railway is the Hakkoda Range of 16 mountains. The Hakkoda Tunnel is located in the northern end of Hakkoda Mountain. It passes through the Hakkoda Range and links the village of Tenmabayashi-mura with Aomori City. The entire length of its 26,455m covers 1/3 of the Tohoku Shinkansen railway between Hachinohe and Shin-Aomori. When it opens, it will link Shichinohe Station (a tentative name) and Shin-Aomori Station.
