Shō Shin

Timeline

1. 1477–1490Shuri Castle · Okinawa IslandAfter Shō En's death his brother Shō Sen'i briefly succeeded, then under court pressure abdicated to the twelve-year-old Shō Shin. Early in his reign the queen dowager and senior ministers governed as regents; he maintained tribute to Ming and continued consolidating second-Shō royal authority over the old Sanzan realm, preparing the political conditions for later centralizing reforms.
2. c. 1490–1510Shuri · Okinawa IslandTo prevent the aji from entrenching themselves, Shō Shin ordered them to reside in Shuri, settled in three districts along the old Yamagami, Yamanaka, and Yamanjo divisions, and replaced private military fiefs with magiri; weapons were confiscated into the royal armory and local forces became magiri troops. At the same time he standardized the hierarchy of caps and hairpins and documentary administration, and the aji gradually became aristocratic officials dependent on the royal court.
3. 1488–1526Shuri · Naha · Okinawa IslandAlongside centralization he vigorously developed Ming investiture-tribute and Southeast Asian entrepôt trade, with Naha becoming an East Asian maritime relay point. The royal court built Shuri Castle and Enkaku-ji and regularized the noro system including the Kikoe-ōgimi to integrate local ritual authority. After nearly fifty years on the throne he died and the crown prince Shō Sei succeeded him; the institutional framework was carried on by later generations.
