Taga Castle, 8th century fortress ruins in Tagajō, Japan
The stone foundations and earthen ramparts of Taga Castle extend across a strategic plateau near the Pacific coast, 10 kilometers northeast of Sendai city.
Founded in 724 by Ōno no Azumabito, the castle served as the administrative center of Mutsu Province and military base for controlling the northern Emishi territories.
The castle site contains an ancient stone monument with inscriptions that detail its construction date and purpose as a provincial capital during the Nara period.
The castle ruins are accessible from Kokufu-Tagajō Station, with blue directional signs guiding visitors through the archaeological site and its remaining structures.
The castle grounds include a 3.4-kilometer perimeter of defensive walls that once featured 5-meter high earthen ramparts topped with wooden fortifications.
