Chamaecyparis, common names cypress or false cypress (to distinguish it from related cypresses), is a genus of conifers in the cypress family Cupressaceae, native to eastern Asia (Japan + Taiwan) and to the western and eastern margins of the United States. The name is derived from the Greek "khamai", meaning ground, and "kuparissos" for cypress.
Chamaecyparis are more common in Japan than Taiwan.
