National Route 6 (国道6号 Kokudō Roku-gō) is a Japanese highway from Tokyo to Sendai that goes through the cities Mito, Iwaki and Sōma. It traces the old Mito Kaidō route from Tokyo to Mito,[1][2] and, for much of its 353.6 kilometres (219.7 mi) length, runs parallel to the Jōban railway line and the Jōban Expressway.

Features

Originating in Chūō, Tokyo (at Nihonbashi, which also marks the origins of Routes 1, 4, 14, 15, 17 and 20), it ends in Miyagino-ku, Sendai (at the Nigatake interchange, junction with Route 45, also the origin of Route 47)

Major cities and villages it passes through include: Kashiwa, Toride, Tsuchiura, Ishioka, Mito, Hitachi, Iwaki, Tomioka, Ōkuma, Sōma, Watari, Iwanuma

The actual terminus is Iwanuma in Miyagi (at the Fujinami intersection) which is the junction of Routes 4 and 6. In the areas north of Iwanuma which overlap with the Route 4, signboards for Route 6 are not posted. The distance from Tokyo to Iwanuma is at total 334.0 kilometres (207.5 mi). This is equivalent to the distance from Mito to Kakegawa / Ichinoseki.

Lengthened Tōkaidō

Route 6 is a part of the lengthened Tōkaidō which connects the Kansai region (Kinai), or Nara and Kyoto in particular, and the Pacific coast of Tōhoku (called the Tagajō).

During the Ritsuryō period, roads from Kinai to the Tagajō were divided into two: the Tōkaidō eastern sea road (via Nagoya, Hamamatsu, Tokyo and Mito) and the Tōsandō eastern mountain road (via Gifu, Shiojiri, Takasaki and Utsunomiya).

During the foundation of Kamakura Kanagawa, Ritsiryō Tōkaidō was divided into two roads: the westward Tōkaidō which connects southern Kantō (Kamakura, Edo, Tokyo) and Kyoto, and the northward Tōkaidō which connects southern Kantō and Pacific coasts of Tōhoku. Since the foundation of Edo, Tōkaidō was narrowed by the Tokugawa Shogunate, the westward Tōkaidō functioned as a seaside road to Kyoto and the northward Tōkaidō functioned as one to the Pacific coasts of Tōhoku.

Ritsuryō Tōkaidō, west from Tokyo is now the Route 1, Ritsuryō Tōkaidō, north from Tokyo, Route 6.

Nuclear dense zone

One side of Route 6 is known as the "nuclear dense zone". Tōkaimura (the first nuclear power plant of Japan), Ōkuma (center of the Fukushima Daiichi nuclear disaster) and Naraha (location of the Fukushima Daini Nuclear Power Plant) are located on adjacent of Route 6.

History

Intersections with other routes

Suspension due to nuclear disaster

Nuclear exclusion barrier at Naraha (27 February 2012)

Due to the Fukushima Daiichi nuclear disaster, access is prohibited to a zone of 20 kilometres (12 mi) radius from the Fukushima Daiichi NPP. Route 6 was blocked for non-authorized traffic between Hirono (the Iwaki side) and Haranomachi (the Sōma side). The ban was lifted in September 2014 after the road decontamination, and vehicles with exception of motorcycles and bicycles, are allowed to pass the stretch.[3]
