Thujopsis is a genus with a single species, Thujopsis dolabrata (asunaro), a large conifer from Japan grown as an ornamental tree. It needs good rainfall or reliable irrigation, as it is not drought tolerant.
Thujopsis () is a genus of conifer in the cypress family, Cupressaceae, the sole member of which is Thujopsis dolabrata. It is endemic to Japan, where it is known as asunaro (あすなろ). It is similar to the closely related genus Thuja (arborvitae), differing in its broader, thicker leaves and cones.
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. In the UK it has gained the Royal Horticultural Society's Award of Garden Merit.
