It is a semi-tall deciduous tree that is distributed in snowy areas of Honshu, mainly Tohoku and Hokuriku regions. This tree grows in slightly damp areas in the mountains, and up to a height of 8-10 m. The branches are hairless, dark purple and have small lenticels. The leaves are obovate-round or obcordate-round, with a concave at the tip, cuneatic bases and low wavy edges.
