Ōshū Kaidō

The Ōshū Kaidō (奥州街道) was one of the centrally administered five routes of the Edo period. It was built to connect the de facto capital of Japan at Edo (modern-day Tokyo) with Mutsu Province and the present-day city of Shirakawa, Fukushima Prefecture, Japan. It was established by Tokugawa Ieyasu for government officials traveling through the area.
