Acer miyabei (Miyabe's or Miyabe maple; Japanese: クロビイタヤ: kurobiitaya) is a species of maple native to Japan, where it occurs in Hokkaidō and the Tōhoku region in northern Honshū.
[2] It is a small to medium-sized deciduous tree growing to 10–20 m tall, with a trunk 30–40 cm diameter with rough, grey-brown bark.
The flowers are produced in spring at the same time as the leaves open, yellow-green, in erect corymbs.
[2][3] It is an endangered species, confined to scattered locations close to streams and rivers.
[2][3][6] This tree is cultivated as an ornamental plant in the United States, but is not common in trade.
