Kyūyō
Kyūyō is an official history of the Ryūkyū Kingdom compiled between 1743 and 1745 by a group of scholar-officials led by Tei Heitetsu. Written in kanbun, and numbering twenty-two scrolls, a supplementary volume in three scrolls documents relations with Satsuma, while a separate volume known as Irō setsuden is a compendium of one hundred and forty-two legends and folktales formerly transmitted orally. Later records continued to be added to the chronicle until 1876. The name, like Kiyō for Nagasaki and Satsuyō for Satsuma, is likely a poetic invocation of "Ryūkyū".
