An evergreen tall tree of the Pinaceae family, Abies genus, grows upright with a neat, conical crown, and, together with the Yezo spruce, is one of Hokkaido's representative conifers (illustration). It can reach a height of 35m and a diameter of 1m, with the bark of the trunk being grayish-white and smooth, but older trees have cracks. It has many resin sacs. The thick branches grow straight horizontally or diagonally upwards. The young branches are densely covered with short brown hairs. The needles are 15-30mm long and spiral. In May, purple-red female cones grow upright from the axils on the upper surface of the previous year's branches at the top of the crown, and male flowers grow downward from the axils of many leaves in the upper half of the previous year's branches.
