Kuraoka's origins are somewhat unclear; it has been suggested that he was either the son of a [[Nagasaki]]-based Japanese family of hereditary [[Nagasaki interpreters|Chinese-language interpreters]], or the illegitimate son of a Nagasaki-based Chinese merchant. He arrived in [[Edo]] from Nagasaki in [[1698]], and eventually attracted the attention of [[Ogyu Sorai|Ogyû Sorai]], who provided him with a position within the Yanagisawa household. | Kuraoka's origins are somewhat unclear; it has been suggested that he was either the son of a [[Nagasaki]]-based Japanese family of hereditary [[Nagasaki interpreters|Chinese-language interpreters]], or the illegitimate son of a Nagasaki-based Chinese merchant.
