Chamaecyparis obtusa is a conifer in the cypress family Cupressaceae, native to central Japan, commonly known as Hinoki Cypress or Hinoki, Japanese: 檜（桧）. 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, 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.

A similar cypress found on Taiwan is treated by different botanists as either a variety of this species (as Chamaecyparis obtusa var. formosana) or as a separate species Chamaecyparis taiwanensis; it differs in smaller cones 6-9 mm diameter with smaller scales.

Uses

It is grown for its very high quality timber in Japan, where it is used as a material for building palaces, temples, shrines, traditional noh theatres, and baths. The wood is lemon-scented and light-colored with a rich, straight grain, and is highly rot resistant.

It is also a popular ornamental tree in parks and gardens, both in Japan and elsewhere in temperate climates including western Europe and parts of North America. A large number of cultivars have been selected for garden planting, including dwarf forms, forms with yellow leaves, and forms with congested foliage.
