National Route 4 (国道4号, Kokudō Yongō) is a major national highway in eastern Honshū, Japan. It has the longest main line of any highway in Japan at 743.6 km (462.1 mi). With its extensions included it is the second longest highway in Japan 854.9 km (531.2 mi) after National Route 58, which is 884.4 km (549.5 mi) long with its maritime sections included.[1] The highway connects Tokyo and Aomori via Utsunomiya, Kōriyama and Morioka.

From Saitama Prefecture to Iwate Prefecture, it parallels the Tōhoku Expressway; from Morioka to Hachinohe, it parallels the Hachinohe Expressway. At its northern terminus it links with National Route 7.[2]

History[edit]

Illustration of the Ōshū Kaidō as it appeared during the Edo period

National Route 4 was initially established as the Ōshū Kaidō (奥州街道) and Nikkō Kaidō (日光街道) as two of the five routes of the Edo period, it was established by Tokugawa Ieyasu for government officials traveling through the area to connect Edo (modern-day Tokyo) with Mutsu Province and the present-day city of Shirakawa, Fukushima Prefecture, Japan. There were also many roads that connected to the Ōshū Kaidō that are included in National Route 4. One such sub-route was the Sendaidō (仙台道), which connected Mutsu Province with Sendai. From Sendai, the Matsumaedō (松前道) connected Sendai with Hakodate, Hokkaidō. Though the Ōshū Kaidō has only 27 post stations, there were over 100 designated post stations when the subroutes are included;[3] some sections and markers of the Ōshū Kaidō in their original state can still be found alongside National Route 4, the Hachinohe Expressway, and Tōhoku Expressway.[4]

On December 4, 1952 First Class National Highway 4 (from Tokyo to Aomori) was established; the route was reclassified as a General National Highway on April 1, 1965.

During the 2011 Great East Japan Earthquake many sections of the route were damaged in the Tōhoku area.[5]
