Quercus gilva is native to Japan, Taiwan, South Korea and south east China. In its native habitat it grows in broad-leaved mountainous forests.
The etymological root of the binomial name Quercus is derived from the Latin name for an Oak tree, but some authorities believe it to be derived from the Celtic quer meaning ‘fine’ and cuez meaning ‘a tree’. Gilva is derived from the Latin gilvum menaing ‘pale yellow’.
