Tohoku Castles
東北Tohoku — the rugged northeastern region of Honshu — was long considered a frontier territory, and its castles reflect centuries of clan rivalries and the fierce resistance of the Emishi people. Many fortresses here occupy commanding mountain ridges and river valleys, built by powerful lords like the Date clan of Sendai. The region's dramatic seasons, especially cherry blossom spring and snow-covered winters, make its castle ruins among the most scenic in Japan.

Kubota Castle (Akita Castle)
久保田城(秋田城) · Kubota-jo
