Shō Nei
Following Hideyoshi's death and after Tokugawa Ieyasu came to power, king Shō Nei was ordered by Satsuma to pay tribute to the Tokugawa shogunate, the newly established government. Shō Nei ignored the demand, largely upon the advice of Jana Ueekata. In 1609, Ryukyu was invaded by Satsuma, in response to this and other refusals of Japanese demands on the part of the Kingdom. The war broke out on April 8, 1609; less than a month later, Satsuma troops landed on the Motobu Peninsula on northern Okinawa Island. Nago Ryōhō was sent by the king to reinforce Nakijin Castle, leading a force of a thousand soldiers. On April 30, Nago met the samurai at Nakijin, but lost half his force and was captured.
