Yuntanza Ueekata Seishō (読谷山 親方 盛韶, 1556 – 1632), also known by his Chinese style name Mō Hōchō (毛 鳳朝), was a bureaucrat of the Ryukyu Kingdom.
Yuntanza Seishō was the fifth head of the aristocrat family called Mō-uji Tomikawa Dunchi (毛氏富川殿内).
[4] Tsuken Seisoku (津堅 盛則, also known as Zen Kōsei 全 興盛) was good at riding horses and Jigen-ryū kendō (swordsmanship), so was intimated with Shimazu Yoshihiro.
In 1616, Uezu Seishō (上江洲 盛相), the eldest son of Yuntanza, was ordered to construct the Taba harbor (田場港) together with Tsuken and Goeku Chōshu (越来 朝首).
The king had an adopted son, Shō Kyō (尚恭, also known as Prince Urasoe Chōryō 浦添 朝良), but he was too young to succeed the throne.
