Oshu City Buried Cultural Properties Research Center
Guidance facility at the Isawa Castle ruins, a nationally designated historic site. We provide an easy-to-understand introduction to the ``world of ancient Ezo,'' including the construction of Isawa Castle in 802 and Aterui, using excavated materials and videos. In addition to being used for excavation of ruins, it is also a facility where you can casually learn about ancient history and archeology.
