- Japanese/Chinese: 懐機 (Kaiki / Huái Jī)
Kaiki (C: Huái Jī) was a Chinese-born official in the Ryukyuan Court, known for having designed the Chôkôtei embankment connecting Naha to the "mainland" of Okinawa Island, as well as sections of the outer gardens of Shuri castle, including the Ryûtan pond & gardens. The latter were one of several key areas used for receiving and entertaining Chinese investiture envoys to the kingdom.
Along with figures such as Lin You and Wang Mao, he was one of a number of Chinese-born officials in Ryûkyû who received formal court robes from the Ming Court, honorarily recognizing him as a member of the ranks of the Ming bureaucracy. He was also appointed by the Chûzan/Ryûkyû government to the Chinese-style posts of changshi (長史) and "prime minister (国相).
