Shimoterao Kanga site

Shimoterao Kanga is an archaeological site and former Buddhist temple in Chigasaki that contains rectangular foundations of administrative buildings arranged around a central structure. The complex includes ruins of storage buildings and other facilities that once supported the operations of this ancient government seat.

The site was founded in the late 7th century as an administrative complex operating under the Ritsuryō system, then was abandoned in the early 9th century. This transition marked the end of a period of centralized government control in the region.

The excavated foundations show four elevated structures that served as rice storage buildings, revealing how ancient Japanese authorities collected and managed regional resources. These storage facilities were essential to the administrative system and demonstrate the practical methods used to govern the area.

The archaeological remains are located beneath Chigasaki Hokuryo High School, with plans underway to relocate the school and develop an archaeological park on the grounds. Access to the site may be limited while development is in progress, so visitors should check current conditions before planning a visit.

A river port discovered on the western side of the complex overlooks the Koide River and reveals the site's importance for ancient regional trade and transport networks. This finding shows that the area was connected to other regions through water routes that facilitated commerce.
