尚寧王
Early in Shō Nei's reign, Japanese warlord Toyotomi Hideyoshi planned an invasion of Korea. Through messengers from Satsuma, he ordered that the kingdom contribute warriors to the invasion efforts, and was refused; he also commanded that Ryukyu temporarily suspend its official missions to China. The mission traveled to Beijing anyway, on business relating to Shō Nei's formal investiture, and related Hideyoshi's plans to Chinese Court officials there. A short while later, Shō Nei sent a missive to Hideyoshi, as was customary upon the installation of a new ruler. He formally congratulated Hideyoshi on having taken over Japan, and on bringing peace and prosperity to the realm, and sent along with the missive a gift of Ming Chinese lacquerware. The letter referred to Ryukyu as a "small and humble island kingdom [which], because of its great distance and because of lack of funds, has not rendered due reverence to you." Shimazu Yoshihisa, lord of Satsuma, then suggested that Ryukyu be allowed to supply food and other supplies instead of manpower. Hideyoshi accepted this proposal, but Shō Nei ignored it, and sent no supplies.
