Acer miyabei,  commonly known as Miyabe Maple, Miyabe’s Maple or in Japanese: クロビイタヤ (Kurobiitaya), is native to Japan. In its native habitat it grows in woodlands and floodplains beside rivers and streams.

The etymological root of the binomial name Acer is from the classical Latin name for the Maple. Miyabei is named for Dr. Kingo Miyabe (1860-1951), a botanist and professor at Hokkaido University.

The landscape architect may find Acer miyabei useful as a specimen tree with attractive autumn leaf colour, particularly in a sheltered position in moist conditions.
