Kōrokan, Archaeological site in Jōnai, Fukuoka, Japan.
The excavated government guest house complex contains structural foundations, ceramic artifacts, and architectural elements from ancient Japanese diplomatic facilities.
Established in the 8th century during the Nara period, the Kōrokan served as an official reception center for foreign diplomats from China, Korea, and other Asian nations.
The site exemplifies early Japanese international relations through its function as a residence where foreign envoys lived for months during diplomatic missions.
Located in Maizuru Castle Park, the archaeological site includes informational displays and markers showing the original building locations within a public lawn plaza.
Archaeological excavations revealed the only surviving structural remains of an ancient Japanese diplomatic guest house, with discoveries including Tang Dynasty ceramics and roof tiles.
