Tei Dō

Jana Ueekata Rizan (謝名 親方 利山^?) (1549–1611), also known by the Chinese-style name Tei Dō (鄭迵^?) (pinyin Zheng Dong), was a Ryukyuan aristocrat and bureaucrat in the royal government of the Ryukyu Kingdom. A member of the Sanshikan, the king's closest advisors, Rizan was the only Ryukyuan official to refuse to recognize the suzerainty of Japan's Satsuma Domain over the kingdom; he was executed as a result.

"Jana Ueekata" is actually a title, not a name, reflecting that Rizan was of ueekata rank, and assigned to the region or territory of Jana. This name structure, along with the fact that he possessed a separate, Chinese-style, name (Tei Dō) was typical of the Ryukyuan aristocracy.

Rizan was, like most officials in the royal government, originally from Kumemura, a community descended from Chinese immigrants and the primary center of learning in the Ryukyu Kingdom. Having been chosen to start on the track to becoming a bureaucrat, he traveled to China to study at the age of 16, remaining at the Imperial Academy in Beijing for six years. He would return there a number of times over the course of his career, heading tribute missions and being involved in other diplomatic activities. In 1606, at the age of 57, he became a member of the Sanshikan, the king's closest advisors.

The court at this time was split between pro-Chinese and pro-Japanese factions; Jana Ueekata was strongly pro-Chinese, and it is said he behaved rudely to Japanese envoys from Satsuma. When Toyotomi Hideyoshi, through agents of Satsuma, demanded that the Kingdom supply forces and supplies to aid in his invasions of Korea, King Shō Nei ignored the demand, largely upon the advice of Jana Ueekata.
