National Route 454 (国道454号,Kokudō Yonhyaku go-juyongō) is anational highway ofJapan that traverses southernAomori Prefecture and briefly crosses into the northeastern edge ofAkita before returning in to Aomori. It connectsHachinohe in eastern Aomori toŌwani in the western part of the prefecture.

National Route 454 begins at an intersection with National Route 104 near the central district of Hachinohe in eastern Aomori Prefecture. From there, the highway travels through the city headed west. It has a junction with the branch route of theHachinohe Expressway that is accessible only if drivers haveelectronic toll collection enabled. Continuing west to the town ofGonohe, the road runs concurrently withNational Route 4 for about four kilometers traveling north. After departing the concurrency heading west once again the road enters the village ofShingō, then crosses into Akita Prefecture. Curving to the north, the road reaches the southern shore ofLake Towada and reenters Aomori Prefecture where it shares a concurrency withNational Route 103 as the roads travel west along the shore of the lake. The concurrency enters Akita Prefecture once again before National Route 103 leaves the concurrency, heading southwest while National Route 454 continues north along the western shore. Upon reaching the northern shore of the lake, the route enters Aomori Prefecture once more and has a junction withNational Route 102 immediately after. At the junction the routes merge, sharing a concurrency traveling northwest away from the lake. After about fifteen kilometers together, the routes separate, with National Route 454 heading southwest throughHirakawa. The road crosses into Ōwani where it terminates upon meetingNational Route 7.^[2]

National Route 454 was established by theCabinet of Japan along its current route in April 1993.^[3]

All junctions listed areat-grade intersections unless noted otherwise.
