This vast site, covering approximately 900 square meters, contains numerous remaining structures that evoke the atmosphere of the time, including government offices, workshops, and soldiers' quarters.
The Tagajo Ruins served as the provincial government office of Mutsu Province (present-day Miyagi Prefecture) from its founding in 724 (the first year of the Jinki era) until its abandonment around the middle of the 11th century. During this time, it played a vital role as the political, cultural, and military center of ancient Tohoku. The ruins encompass a large area and contain numerous remaining structures that provide a glimpse into daily life at that time, including government offices, workshops, and soldiers' barracks. The government office site, in particular, is the central part of the Tagajo Ruins, enclosed by a roughly 1km-long earthen wall, where important state affairs and ceremonies were conducted. Beyond the main government buildings, several other smaller administrative blocks are scattered across the flat areas of the hills. The Tagajo Ruins are counted among Japan's three great historical sites, alongside Heijo-kyo and Dazaifu ruins, and are incredibly significant for understanding Japanese history. A visit to Tagajo Ruins allows you to experience the romance of ancient history while also immersing yourself in the history and culture of the Tohoku region. The commanding views of the Sendai Plain are also breathtaking, offering a delightful blend of historical exploration and natural beauty. The Tagajo Ruins are highly recommended for history buffs, families, and couples alike. Be sure to visit!
