National Route 394 (国道394号,Kokudō San hyaku kyū jūyongō) is anational highway in theJapanese prefecture ofAomori. Route 394 stretches 185 km (115 miles) fromNational Routes 279 and338 inMutsu southwest to National Route 7 inHirosaki.

The route has a total length of 185 km (114.95 mi). It travels southwest across Aomori Prefecture connecting the cities ofMutsu andHirosaki by traveling over theHakkōda Mountains in the center of the prefecture.

National Route 394 was designated as route connecting Mutsu to Aomori in 1982;^[2] however, many of the sections of roadway that make up the highway predate this designation, including a bridge along the highway overLake Ogawara that was built in 1958.^[3] Its routing has changed since its designation. InShichinohe, the road used to parallelNational Route 4 andNational Route 45 for a short distance until March 2015. In the same town on 27 November 2018, the route was moved slightly to the west to better facilitate the junction between it and theKamikita Expressway.^[4]

Improvements on the highway near the interchange with the Kamikita Expressway continue. A project to straighten a 1.9-kilometer-long (1.2 mi) section of the road north of the junction is planned by the government of Aomori Prefecture.^[5]

The route lies entirely withinAomori Prefecture. Distance markers reflect distance traveled from the junction with National Route 338 inRokkasho.
