Chamaecyparis obtusa (Japanese cypress, hinoki cypress or hinoki; Japanese:檜 or 桧, hinoki) is a species of cypress native to central Japan.

It is a slow-growing tree which grows to 35 m tall with a trunk up to 1 m in diameter. The bark is dark red-brown. The leaves are scale-like, 2–4 mm long, blunt tipped (obtuse), green above, and green below with a white stomatal band at the base of each scale-leaf. The cones are globose, 8–12 mm diameter, with 8–12 scales arranged in opposite pairs. The related Chamaecyparis pisifera (sawara cypress) can be readily distinguished in its having pointed tips to the leaves and smaller cones.
