Quercus acuta

Quercus acuta, the Japanese evergreen oak, is an oak native to Japan, South Korea, Taiwan, and China's Guizhou Province and Guangdong Province.[1] Due to its foliage and habitat, it looks very unlike an oak.

It is usually bushy and densely domed, reaching a height of 14 m. The bark is smooth and dark grey. Leaves are dark and glossy above and yellowish beneath. They narrow to a long, finely-rounded tip. The flowers are on a stiff 5 cm catkin.

Often called Japanese white oak or shiro kashi, it is a standard choice for Japanese martial arts practice weapons such as bokken, because it has a uniformly tight grain structure due to its continuous growing season.[2] It should not be confused with the oriental or Asian white oak, Quercus aliena.
