|Notes||A nice castle for castle fans to visit since it is one of the oldest castle sites in the country, and especially on the main island of Honshu. Stop by the tourist information just outside the station to get a map of the castle ruins. The first place to start just outside the station and then you only need to follow the blue signs (even if you can't read them) to get to the other sites.|
Taga Castle was built on the boundary between the Emishi people of the northeast and the lands ruled by the Imperial Court in Kyoto. It was the main military and political base for the pacification of the northeast. It was burned down in a rebellion in 780 but was soon rebuilt. Sakanoue no Tamuramaro moved the military base farther north in 802, but Taga Castle continued to flourish as the political and administrative center. Taga Castle lost it's importance during the period of Northern and Southern courts.
Several of castles of this same type were built pushing farther into the north as new territories were subjugated. Taga Castle is well known for being mentioned in an ancient history text (shokunihonki) and by Matsuo Basho in his famous Oku no Hosomichi.
