Ae Kanga ruins

Ae Kanga ruins are an ancient administrative site with rectangular enclosures surrounded by moats and earthen ramparts. The structure still shows the building foundations that once served the old government.

The site dates from the 8th century and was an administrative center during the Nara and Heian periods. It operated under the Ritsuryō system, which organized Japanese government following Chinese models.

The layout shows how officials and tax collectors worked together and where they stored their records in ancient times. You can see from the ruins how this government institution was organized spatially.

The site is accessible on foot and has excavated areas open for viewing. The grounds are freely accessible to visitors and require no special mobility needs.

Excavations in the 1970s revealed surprisingly that this was no temple but a massive administrative complex with large pillared buildings. This misunderstanding was only cleared up through careful excavation.
