Asaka
Asaka occupies a plateau and basin in southern Mutsu, crossed by the Ōshū Kaidō. In the Edo period seven post stations served travellers along the road through the district, including Kōriyama and Sasagawa. Each supplied people and horses to carry messages and loads onwards; inns and official lodgings received those travelling north and south. Much of the Kōriyama area came under the Nihonmatsu domain in 1643.
