If you are a regular reader, you know I am interested in Japanese Castles and history. The castles in Okinawa are very different from those in the rest of Japan. The castles in Okinawa were part of the Ryukyu kingdom. Zakimi Castle was built in the early 1400s and served as a safeguard again rebels in the north.
This is what Jcastle has to say about this castle -
Zakimi Castle was originally built to check the rising power of the Hokuzan Kingdom to the North. After the Chuzan Kingdom defeated Hokuzan, Lord Gosamaru moved to Nakijin Castle to govern over the area for the Chuzan Kingdom.
