Tosa Kaidō
The Tosa Kaidō is a direct route over the mountains between Tosa (modern day Kochi) and Iyo (modern day Ehime) that was used from ancient times to the Edo era. In Shikokuchūō, the road starts in Kawanoe, passes through Shingu, and continues to Sasagamine ridge in Otoyo Town, Kochi. Parts of the road date back to 793, when it was made an official government route of the Daijo-kan (the central government in Kyoto).Ehime no Furusato Komichi, Higashi Iyo-hen, p.178 Ehime-ken Bunka Shinko Zaidan, 1982 Japanese The road later fell out of use by the government, but continued to be used by travelers and people in Shikoku for the next nine hundred years. From 1718, the Edo shogunate began to use the road for sankinkotai, the policy of forcing the daimyō of every han to move periodically between Edo and his han.
In recent years the Tosa Kaidō has been maintained through the efforts of volunteers. Hikers can walk on a footpath from Kawanoe to Otoyo, Kochi. (The path sometimes joins Ehime prefectural road 5.)
