- Japanese: 奥州街道 (Ôshû kaidô)
The Ôshû kaidô was a major Edo period highway running north from Edo to Shirakawa 白河 in the northern province of Mutsu (also known as Ôshû). Starting at Nihonbashi, it split off from the Nikkô Road at Utsunomiya. The highway's ten stations were located roughly 7.9 km apart, and had a total of 11 honjin and 11 waki-honjin between them. As of 1843, each station had an average population of 1,186 people and an average of 27 hatagoya.
