Kōshū Kaidō
The  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. 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. Stations of the Kōshū Kaidō
