Young-mi (ヨンミ, Yonmi) (born September 19, 1980 in Tokyo, Japan) is a Korean gravure idol and JAV (Japanese adult video) actress. Aside from being featured in photobooks and various gravure and adult DVD releases she also appeared in the 2005 exploitation film Lady Ninja Kasumi, Volume 1, playing the lead character Kasumi.
There is some confusion over all the names Young-mi goes by. Her Japanese name is Emi Kitani (木谷映美, Kitani Emi). She uses Yon-mi (ヨンミ, aka Yonmi) for her modeling and acting. Finally, she goes by Reina Mizuki (美月れいな, Miduki Reina) in her adult video career.
