In a Nutshell:
* Thujopsis (pronounced "Thuyopsis") is a conifer in the cypress family (Cupressaceae), the sole member of the genus being Thujopsis dolabrata. It is endemic to Japan, where it is named asunaro . It is similar to the closely related genus Thuja (Arborvitae), differing in the broader, thicker leaves and thick cones. It is also called hiba, false aborvitae, or hiba arborvitae.
* Thujopsis is a medium to large evergreen tree, reaching up to 40 m tall and 1.5 m trunk diameter, with red-brown bark which peels in vertical strips. The leaves are arranged in decussate pairs, scale-like, 3–10 mm long, glossy green above, and marked with vivid white stomatal bands below; they have a distinctive thick, almost fleshy texture. The seed cones are ovoid, 7–15 mm long and 6–10 mm diameter, with 6-12 thick scales, brown with a violet-white wax bloom when fresh.
* The asunaro is a valued ornamental tree both in its native Japan, where it is commonly planted around temples as well as in gardens, and also in Europe and North America. In the latter two regions, planting is confined to areas with good rainfall or in gardens with reliable irrigation, as the species is not drought tolerant. It has gained the Royal Horticultural Society's Award of Garden Merit.
* It is also used to a small extent in forestry in Japan, grown for the valuable wood, which is durable and scented, similar to that of Thuja plicata. more...
* The bark is used for match cord, for filling (caulking) between boards on boats etc to prevent water leaking. Wood - soft, durable, elastic. Used for construction, cabinet work, water pipes, ship building etc. more...
