Ōōso
Ououso (汪応祖, Ōōso, ?–1413) was the 3rd king of the Nanzan kingdom. He ruled from roughly 1402 to 1413.
Ououso was the second son of the former king, Oueishi. Ououso built a castle (gusuku) at Tomigusuku (豊見城), and established himself there. It was said that Ououso had studied in Nanjing for a long time, and he learned how to build a dragon boat there. After his coming back to Ryukyu, he built plenty of dragon boats, and held Dragon boats races ([[[Okinawan language|Okinawan]]: 爬竜 or ハーリー] Error: {{nihongo}}: text has italic markup (help), Haarii) in May every year.
Ououso succeeded his father as king in 1402. He also pay tribute to Ming China as his father did, and, according to Chūzan Seifu (中山世譜), Ououso had donated several eunuchs to Ming court, but Yongle Emperor refused.
Ououso died in a coup d'état which was conducted by his elder brother Tafuchi. Tafuchi seized the power after his death, but was killed by Taromai in the same year.
