Gushikawa Castle

Gushikawa Castle is a fortress positioned on limestone cliffs at Cape Kiyan with stone walls built in nozura-zumi style and two distinct enclosed sections. The structure takes advantage of the natural rocky terrain and its elevated location above the water.

Archaeological evidence shows the fortress was active between the late 12th and 15th centuries, later becoming part of the Ryukyu Kingdom's defensive system. This strategic position made it important for controlling access to the surrounding waters over many generations.

The site reflects Ryukyuan building methods using local limestone blocks stacked without mortar, as seen throughout the island's defensive structures. Visitors can observe how the fortress integrated these traditional techniques into its perched location on the cliffs.

A small parking area accommodates five vehicles roughly 50 meters from the ruins, and a mini-bus service connects the site to Itoman city center. Plan to walk the final distance and wear sturdy shoes since the terrain around the fortress is rocky and uneven.

This fortress holds the distinction of being the southernmost structure of its kind on Okinawa's main island and has a presently sealed pathway that once led directly to the Pacific Ocean. The hidden connection to the water hints at how people once used this elevated position as both shelter and a lookout point.
