尚寧王
At this time, Japan was unified by the "daimyō" Toyotomi Hideyoshi. Hideyoshi planned to invade Korea and China, and demanded that the Kingdom supply 10 months' rations for 7,000 troops to aid in his invasions through agents of Satsuma. The court was split between pro-Chinese and pro-Japanese factions; Nago was pro-Japanese, suggested that king Shō Nei should obey, but this suggestion was strongly opposed by his colleague Jana. Jana suggested that all the demands should be rejected. However, both of their advice was not accepted by king Shō Nei; the king sent a warning to China in 1591, and sent only half of the demanded supplies in 1593.
