Cryptomeria (literally "hidden parts") is a monotypic genus of conifer in the cypress family Cupressaceae, formerly belonging to the family Taxodiaceae. It includes only one species, Cryptomeria japonica (syn. Cupressus japonica L.f.). It used to be considered by some to be endemic to Japan (see remark below under 'Endemism'), where it is known as Sugi ().[2] The tree is called Japanese cedar[3] or Japanese redwood[4][5] in English. It has been extensively introduced and cultivated for wood production on the Azores.
