This tree, while retaining the acorn most Oaks have, lacks the usual scallop edged leaf so closely associated with this family. Instead, the Japanese Blue Oak has long, glossy, smooth leaves that contain hairs on their underside. This tree is particularly susceptible to cold damage, which can destroy its leaves. This tree can be identified by dense foliage, and a surplus of lower leaves.
