He was dispatched to Kyoto at some point in the 1520s-1560s to have the royal sword Jiganemaru (治金丸), a tribute/gift to the kingdom from Miyakojima, polished. After he returned to Ryûkyû, he became aware that the swords had been switched, and so he returned to Kyoto to find and retrieve the king's sword. He successfully returned the royal sword to Ryûkyû some three years later. Praised for his dedication and loyalty, he was buried in a special tomb just outside of Shuri castle.
