History

National Route 101 was established by the Cabinet of Japan between the city of Aomori and Noshiro, Akita in 1953.[2] In 1993, the northern terminus of the highway was moved south from Noshiro to its current location in the city of Akita.[3]

On 28 December 2018, Oibanasaki Tunnel in Oga, Akita was closed because the risk of a landslide was deemed too high. The tunnel is scheduled to be reopened in 2020.[4]
