is a national highway of Japan connecting Aoba-ku, Sendai and Aomori. Alongside Japan National Route 6, it is a main route along the Pacific coast of eastern Japan. It is paralleled closely by the incomplete Sanriku Expressway between Sendai and Hachinohe.
Route description
National Route 45 has a total length of . The northernmost of the highway between its northern terminus in central Aomori and Japan National Route 102 in Towada is a concurrency with Japan National Route 4 where Route 45 is not signed until it diverges from Route 4. From there it independently begins heading southeast towards the coastal cities of Hachinohe, Kuji, Miyako, Kamaishi, Kesennuma, and Ishinomaki on the way to its southern terminus in Sendai.
History
Route 45 was originally designated on 18 May 1953 as second-class routes 102 and 111 connecting Hirosaki to Hachinohe and Hachinohe to Sendai, respectively. On 1 April 1963, Route 102 was truncated to its current route with the section between Towada and Hachinohe incorporated into the newly formed first-class Route 45 along with the entirety of Route 111.
Many sections of the highway along the Sanriku Coast were inundated, destroyed, or swept away by the 2011 TÃ
Âhoku earthquake and tsunami event.
