Emperor Go-Mizunoo was the 108th Emperor of Japan, according to the traditional order of succession. Go-Mizunoo's reign spanned the years from 1611 through 1629. This 17th-century sovereign was named after the 9th-century Emperor Seiwa and go-, translates as "later", and thus, he could be called the "Later Emperor Mizunoo". The Japanese word go has also been translated to mean the "second one", and in some older sources, this emperor may be identified as "Mizunoo II".
