| Additional information |
The Sekōtsūhō was cast during the reign of Shō Toku, the sixth king of the First Shō Dynasty, at a moment when the Ryukyu Kingdom was operating as one of the most active maritime trading intermediaries in East Asia — routing goods between China, Japan, Korea, and Southeast Asia. Ryukyuan coinage of this period is exceptionally scarce in part because the kingdom relied heavily on imported Chinese cash for everyday exchange, making domestic issues short-lived experiments rather than sustained monetary programs.
The First Shō Dynasty itself collapsed just two years after Shō Toku's death, swept aside in 1470 by Shō En, founder of the Second Shō Dynasty.
