The early Korean records allude to the presence of Ryukyuan individuals in charge of firearms, but it is unclear if indeed such a post or position existed at the time. The ''[[Ryukyukoku yuraiki|Ryûkyû-koku yuraiki]]'' indicates a "head of production of firearms / fire arrows"<!--比屋勢頭親雲上 or 火矢勢頭親雲上--> (O: ''hyaa shii du [[peechin]]'') named Matsuuji (in the Japanese reading of the name) who is held to have introduced [[fireworks]] to Ryûkyû in [[1479]], so such a position seems to have been in place at that time. Furthermore, an official known as the ''[[boraakugami bugyo|boraakugami bugyô]]'' is known to have had gunpowder technology among his responsibilities.<ref>Uezato. pp77-78.</ref>
