Quercus acuta is usually bushy and densely domed, reaching a height of 14 meters.

[5] In Japan, it is called akagashi (赤樫 - あかがし), but is also known by the names oogashi (大樫 - オオガシ) and oobagashi (大葉樫 - オオバガシ).

Like shirakashi (白樫 - しらかし) (Quercus myrsinifolia), whose wood is often called shirokashi outside of Japan, and other related sub-genera, Japanese Evergreen Oak, or akagashi, is a preferred choice for Japanese martial arts practice weapons such as bokken.

[8][9] This is due to its uniformly tight grain structure resulting from its continuous growing season.

It should not be confused with the oriental or Asian white oak, Quercus aliena.
