A large, narrow conifer with a trunk to 50 m (167 ft.) tall and to about 2 m (7 ft.) in diameter. The foliage consists of finely divided branchlets, densely covered with tiny, scale-like leaves. It is native to the Japanese Islands of Honshu and Kyushu, where it grows between 300 and 2600 m (1000 and 8500 ft.) In cultivation it is best suited to cold, humid climates in the USDA hardiness zones 5 to 9. It is hardy to very severe freezes. Germination is sporadic and can take well over a year. Cold stratification usually improves the process. It is a popular ornamental and can also be trained into a bonsai.
