Nikkō Kaidō
Much of what is presently National Route 119 was preceded by the northernmost section of the Nikkō Kaidō, a road established by the Tokugawa shogunate during the Edo period. It connected Edo and the Shrines and Temples of Nikkō. Secondary National Route 119 was established by the Cabinet of Japan between of Nikkō and Utsunomiya in 1953 along pre-existing roads, mostly made up of the section of the Nikkō Kaidō between the two municipalities. In 1963, the Cabinet of Japan amended the highway's designation, upgrading it from its secondary status to a full national highway.
