- Pinus thunbergii is a small evergreen tree that can reach heights of about 20-30 ft (6-9 m) tall and about 20-35 ft (6-11 m) wide in cultivation. In its native habitat it can grow to over 100 ft (30.5 m) tall. The branches are usually large and contorted, spreading horizontally or hanging down. It is native to northeastern China, Korea and Japan.
- The leaves are usually a dark green. The needles are 5-7 in long and twisted. Needles are borne in groups of two per bundle.
- Seed cones are either solitary or held 2-3 together. They are about 1.6-2.4 x 1.2-1.6 in (4-6 × 3-4 cm) long by wide and deciduous. The seeds are obovoid to ellipsoid in shape.
