It is unclear precisely when the ''Ryûkyû-koku jiryaku'' was written, but its contents hint that Hakuseki wrote it either concurrently with ''Nantôshi'' (c. [[1719]]), or at some later time while revising ''Nantôshi''. References to ''Nantôshi'' and to his conversations with [[Ryukyuan embassies to Edo|Ryukyuan envoys]] in [[1710]] and [[1714]] place the text no earlier than 1719 (and certainly no earlier than 1710 or 1714). The ''Ryûkyû-koku jiryaku'' also does not state the reason for its composition - unlike many texts, which explain this in the preface. However, scholars believe it was likely in some fashion commissioned or proposed by the shogunate, and was then composed to be formally presented to the shogunate. | It is unclear precisely when the ''Ryûkyû-koku jiryaku'' was written, but its contents hint that Hakuseki wrote it either concurrently with ''Nantôshi'' (c.
