Shimashi Ozato Castle


Shimashi-Ozato Castle Ray 1.jpg


According to the Chuzanseifu(中山世譜), Shimashi-Ozato Castle was founded by the Shimashi-Ozato Aji(Lord) in the 14th century.

In 1402, Sho Hashi, the lord of Sashiki Castle, conquered Shimashi-Ozato Castle. After Sho Hashi conquered the three “Sanzan Domains” and unified them to form the Ryukyu Kingdom in 1429, the Seiden (main palace) at Shimashi-Ozato Castle became an outlying imperial palace. Shimashi-Ozato Castle’s Seiden was the second biggest palace in the Ryukyu Kingdom after Shuri Castle’s Seiden.

Archaeological investigation in 1991 found pottery, coins, and other artefacts dating to the 14th to 16th century at the castle ruin and former castle town.

Visit Notes

Shimashi-Ozato Castle is around an 8-minute walk from the Nishihara Iriguchi bus stop after getting there by a mini-bus. They run from Nanjo City Hall roughly once every two hours. This castle ruin is quite extensive with lots of sacred shrines in and around the castle ruin. When I visited, there were some other people visiting the castle ruin just for the shrines.

All the photos uploaded with this profile were taken in early May 2022.

This Ryukyuan gusuku ruin way exceeded my expectations. I had expected just some collapsed stone walls, but the amount of stone wall remnants remaining is quite impressive as is the size of this Ryukyuan fortress. My wife and spent nearly 90 minutes on site exploring its stone wall ruins and multiple shrines located in and around the castle, but I reckon we could have done with another 30 minutes as there were a lot of ruins to see and photograph.
