Matsumaedō (nonfiction)

The Matsumaedō (松前道) was a subroute of the Ōshū Kaidō, one of the Edo Five Routes of Japan. It connected the Sendaidō's terminus at Sendai Castle with the northern tip of modern-day Aomori Prefecture. It was established by Tokugawa Ieyasu for government officials traveling through the area. The route is named after the Matsumae Domain, the only Edo period feudal domain to have been located in Ezo (now called Hokkaidō); Matsumae was accessible by boat from the northern terminus of the Matsumaedō.
