Sato Kanga ruins

The Sato Kanga Ruins, located on the Johara Plateau in Ōita City, Kyushu, Japan, represent a significant archaeological site. These ruins date back to the Nara to Heian periods, showcasing the remnants of a government administrative complex under the Ritsuryō system. Excavations have unearthed pit dwellings and large pillared buildings arranged in a U-shaped configuration, characteristic of the standardized layout of kanga government offices inspired by Chinese design. Serving as the administrative center of ancient Amabe District, these structures were constructed in the mid-7th century and were subsequently abolished in the early 8th century, with administrative functions moving westward. The site's designation as a National Historic Site in 2022 underscores its historical and cultural significance.
