Description

Tree or shrub to 8(-12) m, with trunk to 0.3(-0.6) m in diameter. Bark reddish brown, weathering grayish brown, peeling  in elongate scales and becoming furrowed with age. Crown dense and fairly regular. Branchlets generally remaining green in the second year, sometimes becoming shiny brown. Leaves needlelike, well separated from one another, spreading flat or raised in a V, shiny to dull dark green to yellowish green or bluish green above, duller beneath, the pale green to grayish green stomatal bands about twice as wide as the midrib region, each band with 12-15 lines of stomates. Needles (1-)2-3.5(-5) cm long, 2.5-4 mm wide, sword-shaped, straight or slightly curved forward, nearly parallel-sided, tapering abruptly to the roundly triangular tip, with a soft point less than 1 mm long, and to the broadly and roundly wedge-shaped base on a very short, thick petiole, flat around the midrib, the edges flat or narrowly turned down. Pollen cone clusters 4-8(-10) mm in diameter, with 6-10 pollen cones on a short stalk 3-4 mm long. Seed cones in groups of one or two (to six) on stalks 6-8(-12) mm long. Seeds (1.5-)2-2.5(-3) cm long, the skin passing through coppery yellow to red or purplish with maturity, obscurely ribbed.

Common throughout Korea and the main islands of Japan. Scattered in the understory of deciduous hardwood forests; 1-1,000 m.
