## Summary

The sika deer, also known as the northern spotted deer or the Japanese deer, is a species of deer native to much of East Asia and introduced to other parts of the world. Previously found from northern Vietnam in the south to the Russian Far East in the north, it was overhunted to the brink of extinction in the 19th century. Protection laws were enacted in the mid-20th century, leading to a rapid recovery of their population from the 1950s to the 1980s.
