Sika deer and established woodlands, and public and private forestry bodies adopt policies of rigorous year-round culling. The main predators of sika deer include tigers, wolves, leopards, and brown bears. Lynx and golden eagles target fawns. Velvet antler (dried immature antlers) is a popular ingredient in traditional Chinese medicine, and sika in China were domesticated long ago for the antler trade, along with several other species.

Japan is the only country in eastern Asia where sika deer were not farmed for velvet antlers.
