Zakimi Castle: Discover Okinawa’s Hilltop “Gusuku” Fortress Ruins
Imagine Okinawa, and you’ll probably see turquoise seas and sandy beaches in your mind’s eye. Not so long ago, however, the islands of Okinawa were the territory of the Ryukyu Kingdom, and much of that history is still easy to find – if you bother to take a look. Tucked away in Yomitan Village is a place that tells another side of the island’s story – Zakimi Castle, a 15th-century fortress built by the legendary samurai lord Gosamaru.

Constructed on a hilltop overlooking the sea between the years of 1416 and 1422, Zakimi was designed to defend central Okinawa during the Ryukyu Kingdom’s turbulent Three Kingdom Period (三山時代, also called the “Sanzan era”). Almost 600 years later, the unique Ryukyuan architecture and historical significance earned Zakimi Castle a spot on the list of UNESCO World Heritage Sites.

A Castle That Survived the Centuries

Unlike many other Okinawan castles, Zakimi escaped destruction in the centuries after it was built, although sections of the walls were damaged during World War II when it was used by the Japanese military and later as a U.S. radar base. Thanks to careful restoration efforts, the site has been restored to its former majesty, helping the spot to become a part of a UNESCO World Heritage Site, alongside other gusuku ruins, in the year 2000.
What to Expect When You Visit Zakimi Castle


While the remains of Zakimi Castle may not feel like a full, functioning fortress anymore, the stone walls are more than just a ruin – this spot is an open-air museum of Okinawan history. Its beautifully curved stone walls, built with sophisticated techniques like aikata-zumi masonry, are among the finest examples of architecture in a “gusuku” – an Okinawan stone-walled fortress. The arched gate is the oldest of its kind in Okinawa, making it a beautifully preserved glimpse into Ryukyuan craftsmanship, and a popular photo spot as well.

Visitors can climb sections of the walls for panoramic views stretching to Naha, the East China Sea, and even the Kerama Islands on a clear day. Beneath the pine trees, the walk up feels peaceful, and the grounds are free to enter at any hour. Plus, visitors looking for a little more context can head right next door, where the Yuntanza Museum provides exhibits on archaeology, folklore, and the Battle of Okinawa. It’s a worthwhile stop if you’d like to go deeper into Yomitan’s cultural history.

If you’re looking for a break from all the beautiful beaches, Zakimi Castle is a perfect place to learn a little about Ryukyu history and Okinawa’s dramatic past! Add it to your Okinawa itinerary alongside other beautiful sites like Cape Manzamo and Bise Fukugi Tree Road.
