Amazaki Castle, Maritime fortress in Imabari, Japan
Amazaki Castle stands on a small island measuring 200 meters in length and 50 meters in width near the coast of Omishima Island.
The castle was constructed in 671 as a defensive structure against potential invasions from Tang forces, making it one of Japan's earliest maritime fortifications.
The Murakami clan utilized this fortress as their naval base, distinguishing themselves as the only sea clan to establish island castles in the region.
The castle ruins become accessible during strong ebb tides when a temporary sandy pathway connects the site to Omishima Island from April through July.
Stone walls reaching 5 meters in height once encircled the island, dividing the fortress into northern central and southern secondary sections.
