Shō On (尚 温, March 21, 1784 – August 8, 1802) was king of the Ryukyu Kingdom from 1795 to 1802.
However, Shō On was only 11 years old, his teacher Sai Seishō (蔡世昌) became the Kokushi (国師), serving as the king's regent.
The Kokugaku (国学) was established as the National Academy of the Ryukyu Kingdom in Shuri Castle on 1798.
But the idea of equal education was not accepted by the Kumemura people, so they launched a rebellion against the reform, and Sai Seishō died in the incident.
The rebellion was quickly put down, and some education privileges of Kumemura people were abolished.
