What is Japanese ash

Japanese ash (Fraxinus japonica) is a deciduous tree native to Japan in the family Oleaceae.
It grows naturally in sunny locations in warm mountainous areas in the northeastern to central regions of Japan.
The tree is 10-15 m tall with a semicircular trunk and grayish-white bark.
The leaves are green, 25-30 cm long, pinnately compound, with serrated edges, and are attached to the branches in opposite pairs.　
It is dioecious. In May and June, conical inflorescences grow from the leaf axils and produce small, petal-less, pale purple flowers.
In August and September, it produces brown spatulate winged fruits 3 to 4 cm in diameter.
The tree is used as a garden tree, roadside tree, garden plantation, and rice rack. The wood is used for building materials, furniture, and equipment such as baseball bats and rackets.
