奥州街道
In addition to the established use of traveling from Edo to Mutsu Province, there were also many roads that connected from the Ōshū Kaidō. One such sub-route was the Sendaidō (仙台道), which connected Mutsu Province with Sendai. The terminus for the Sendaidō is in Aoba-ku in modern Sendai. From there, the Matsumaedō (松前道) connected Sendai with Hakodate, Hokkaidō. Though the Ōshū Kaidō has only 27 post stations, there were over 100 designated post stations when the subroutes are included.
