Kōshū Kaidō
From Wikipedia, the free encyclopedia
The Kōshū Kaidō (甲州街道) was one of the five routes of the Edo period. It was built to connect Edo (modern-day Tokyo) with Kai Province in modern-day Yamanashi Prefecture, Japan. The route continues from there to connect with the Nakasendō's Shimosuwa-shuku in Nagano Prefecture.[1] Many feudal lords from Shinano Province made use of the road during sankin-kōtai, including those from the Takatō, Suwa and Iida domains.
The Kōshū Kaidō's route is followed closely by the modern Route 20.
