Rhus succedanea L. Toxicodendron succedaneum, the wax tree,[1] Japanese Hazenoki tree (Sumac or wax tree), sơn in Vietnamese or charão in Portuguese, is a flowering plant species in the genus Toxicodendron found in Asia, although it has been planted elsewhere, most notably Australia and New Zealand.

In East Asia, in particular in Japan, traditional candle fuel (also called Japan wax) was produced, among other sumac plants, from Toxicodendron succedaneum crushed fruits rather than beeswax or animal fats.

Japan wax is sold in flat squares or disks and has a rancid odor.

The fatty-acid methyl ester of the kernel oil meets all of the major biodiesel requirements in the USA (ASTM D 6751-02, ASTM PS 121-99), Germany (DIN V 51606), and the European Union (EN 14214).

The fruits are edible, though their consumption is not recommended because of the general toxicity of the plant.
