Route 339 is a general national highway that runs from Route 7 in Hirosaki City, Aomori Prefecture, through Fujisaki Town, Minamitsugaru District, Itayanagi Town, Kitatsugaru District, Tsuruta Town, Goshogawara City, and Nakadomari Town, Kitatsugaru District, to the intersection of Route 280 in Sotogahama Town, Higashitsugaru District, Aomori Prefecture. The section connecting Tappizaki and Kodomari in Kitatsugaru District is commonly called the "Tatsudomari Line". The northern end of Route 339, near Cape Tappizaki, is designated as a national highway, but there is a section consisting of stairs and sidewalks that are inaccessible to vehicles, making it a famous tourist attraction known as the "Kaidan Kokudō (Stairway National Highway)".
