Route 7 serves as a frontage road to the expressway and as an eventual access point to it at Aomori-chūō Interchange.

After passing the institution the road divides with the western route serving as a bypass to the main highway to the east.

After passing through a residential area, the main highway and bypass begin the ascent of the Hakkōda Mountains.

After a short descent, the road meets Japan National Route 394 at a signaled intersection.

Just a couple of kilometers from here is Sukayu Onsen, the snowiest inhabited place on earth famous for its 1,000 person mixed-use bath.

This section of road is closed during the winter, but is reopened in early spring as a "snow corridor" where visitors are allowed to walk.
