Distribution and notes. Widespread in Asia extending from Annam, north to Japan and east to New Caledonia. The species is commonly found growing in primary forests of low to medium elevations in Taiwan.
Based on narrower leaflets of specimens collected from northern Taiwan, Masamune (1964) described a new taxon, C. japonica var. taiwaniana. However, that name is illegitimate, as he did not designate any type materials. Our observations indicate that the leaf morphology of C. japonica is quite variable and that shape and size may vary even within the same individual. Since C. japonica var. taiwaniana lies within the range of leaf morphology, we do not recognize this variety.
