What are some cool Japanese last names? And what are some darker (names with darker meanings) female names?

When I say dark I mean something like, Rain, or shadows, or love, or my favorite flowers: Amaranth, Bleeding hearts, and Snap-Dragon. I want a first, middle, and last name. THANKS!|||Lol are you Japanese or What ?? ^.~|||I thought you said you were Japanese in your last question..
