Gushikawa Castle (Kume)

Gushikawa Castle, known locally as Gushichaa Gushiku, is a historic Ryukyuan gusuku fortification situated in the Nakandakari neighborhood of Kumejima town on Kume Island, Okinawa Prefecture, Japan. Perched on a hill that juts into the East China Sea, the site is naturally defended by steep cliffs on three sides. Constructed primarily from Ryukyuan limestone and wood during the 15th century, the castle complex features four distinct enclosures surrounded by low rock walls. The northernmost enclosure likely served as a watchtower due to its elevation, while the southwestern area contains foundation stones indicating the location of the main residential building and forecourt.

The castle holds significant historical value tied to local feudal conflicts and the centralization of the Ryukyu Kingdom. Chronicles state it was originally built by Madafutsu Anj on a sacred site before being captured by rival lord Manikudaru Anj. Following these internal struggles, the fortification was ultimately destroyed in the early 16th century by an army dispatched by King Shō Shin to unify the region. Archaeological excavations conducted between 1999 and 2007 uncovered ceramics dating back to the 14th and 15th centuries, confirming the timeline of its occupation and use.

Today, Gushikawa Castle exists as well-preserved ruins and has been designated a National Historic Site of Japan since 1975. It is open to the public, offering visitors a chance to explore the ancient stone enclosures and enjoy panoramic views of the surrounding ocean. From the castle grounds, one can also see the notable Miifugaa rock formation nearby. As a protected cultural heritage site, it stands as a tangible reminder of the martial history and architectural traditions of the Ryukyu Kingdom on Kume Island.
