They contain sunbstance called ‘urushiol’, which we touch the branch or the leaf, resulting in our getting a rash from lacquer. Cortex of the young trees is tinged with gray-white color, and diamond-shaped lenticel stands out, while the one of the adult trees is split shallow vertically with the dark-brown patterns. The trunk is about 5 cm wide. The leaf is an imparipinnately compound leaf, consisting of 9 to 17 lobules as one. Lobulus is egged-shaped about 5 to 12 cm long, 3 to 6 cm wide with the sharp top, and only young leaf has a sawtooth (Kyoshi: tooth-like rough part like a saw at the root of a leaf) at the edge. They turn into red color in autumn. The blossom seasons are about May to June and a dioecious plant (Shiyuuisyu). From the side of the leaf, does inflorescence (Kajo: stalk blooming flowers), about 15 to 25 cm long, sprout with small yellow flowers.
