The trunk is upright, and the larger ones can reach 40 meters in height and 1 meter in diameter. However, above the tree line in high mountains, it becomes a small tree or shrub. The bark is gray-white or gray-blue-purple and smooth. The annual branches are densely covered with short reddish-brown hairs. The leaves are linear and slightly wider upwards, with a round or slightly concave tip, 1 to 2 cm long, dark green glossy on the upper surface, and wide white stomatal lines on the underside. Monoecious. It blooms in June, and both male and female flowers grow at the ends of the branches. The cones are large, elliptical, 5 to 10 cm long and 3 to 5 cm wide, and ripen to a deep blue color in September and October. The wood is used for construction, tools, pulp, etc. It grows in large colonies on gently sloping mountain areas with deep, moist soil, and is distributed in the subalpine zone north of the Chubu region of Honshu.
