Japan National Route 1

National Route 1 (国道1号, Kokudō Ichi-gō) is a major highway on the island of Honshū in Japan. It connects Chūō, Tokyo in the Kantō region with the city of Osaka, Osaka Prefecture in the Kansai region, passing through the Chūbu region en route. It follows the old Tōkaidō westward from Tokyo to Kyoto, and the old Kyo Kaidō from there to Osaka. Between Tokyo and Aichi Prefecture it parallels the Tomei Expressway; from there to Mie Prefecture, the Higashi-Meihan Expressway, and from Shiga Prefecture to Osaka, the Meishin Expressway. It has a total length of 760.9 kilometers (472.8 mi). At its eastern terminus in Nihonbashi, Chūō, Tokyo, it meets National Routes 4, 6, 14, 15, 17, and 20.

Route description

 

National Route 1 and the Tōmei Expressway traveling parallel to one another on the shore of Suruga Bay near Mount Fuji in Shizuoka Prefecture

The main line of National Route 1 has a length of 638.4 kilometers (396.7 mi). When bypasses signed as National Route 1 are included, its total distance increases to 777.9 kilometers (483.4 mi).^[4] Out of all of the national highways of Japan, it is the second longest land-based route after National Route 4,^[5] though National Route 58 is the longest route when seabound routes are factored in.^[6]

The highway's origin and eastern terminus lies at Nihonbashi in Tokyo's Chūō ward. At Nihonbashi it meets national routes 4, 6, 14, 15, 17, and 20. The highway passes through the cities of Kawasaki, Yokohama, Odawara, Numazu, Shizuoka, Hamamatsu, Nagoya, Yokkaichi, Ōtsu, and Kyoto. Its endpoint and western terminus lies in the Umeda district of Osaka's Kita ward. In Umeda, it has a junction with national routes 2, 26, 163, 165, 25, and 176.^[4]

History

See also: Tōkaidō (road)

National Route 1 was preceded by the Tōkaidō between Tokyo to Kyoto, and the old Kyo Kaidō from Kyoto to Osaka. The road's construction was order by the first shōgun of the Edo period, Tokugawa Ieyasu. It served to link the old capital of Japan, Kyoto, to Tokugawa's new capital, Edo. The Tōkaidō's post stations, known in Japanese as shukuba, were captured by the printmaker Utagawa Hiroshige in his ukiyo-e prints, The Fifty-three Stations of the Tōkaidō.^[7]

In 1919, the first Road Act was passed, establishing a highway also called National Route 1 between Tokyo and the city of Shingū in Wakayama Prefecture partially along the current route.^[8] On 4 December 1952 the route was designated by the Cabinet of Japan as Primary National Highway 1 between Tokyo and Osaka, establishing the highway almost entirely along its current routing. On 1 April 1965 the route was redesignated as General National Route 1.^[9]
