What is Japanese black pine

Japanese black pine (scientific name: Pinus thunbergii) is a tall evergreen coniferous tree in the family Pinusceae, native to Japan. The bark is grayish-black, the shoots are whitish and the trunk is strong. It is also called a pine tree because its hard leaves and branches spread out strongly. In contrast, red pinehas a slender trunk, reddish bark, soft leaves, and foliage that gently spread into a cone shape, hence the name "mematsu" (female pine). The pine needles are attached to the branch in bunches of 2-5 pine needles in one place, but after a few years they break away from the branch and fall off. The flowers are dioecious and each plant has a male flower with only stamens and a female flower with only stamens. The fruit is spherical and is called pine needle. The small, light yellow scales between the pine cones are the pine nuts; the black pine ones are too small to be used. Injuring the pine tree removes the pine sap, but over time it hardens into kohaku (amber). It has been popular in Japan since ancient times and is used in song and dance and as a tool holder for traditional art. Along with the Japanese red pine, the black pine is a representative of the Japanese larch.
