Gushikawa Chōei

Gushikawa Wōji Chōei, also known by Kume-Gushikawa Wōji Chōei and his Chinese style name Shō Kyō, was a member of the royal family of the Ryukyu Kingdom who served as sessei, a post often translated as "prime minister", from 1654 to 1666.
Gushikawa Chōei was the seventh son of Kin Chōkō and Shuriōkimi Aji-ganashi. He was also a half-brother of King Shō Hō. After Shō Shitsu succeeded the throne, he led a mission Edo in 1649.
