What is Quercus crispula

Quercus crispula or Mizunara, (scientific name: Quercus crispula) is native to China and Japan and is a deciduous broad-leaved tree in the family Fagaceae. It grows naturally in the mountains of Hokkaido to Kyushu in Japan. Because it contains a lot of moisture, it is difficult to burn and has strength. The leaves are egg-shaped and have serrations at the edges of the leaves. The leaves are green at first, but yellow in autumn. It is hermaphroditic. Flowers bloom in the spring and become windy flowers. The fruits are acorns, but they are sour and not edible. Lumber is used for high-end furniture, whiskey barrels, high-grade charcoal, and firewood for cultivating shiitake mushrooms.
