In Search of Oka Naomi

I have searched the internet in both English and Japanese for information on this beautiful actress and have come up with very little, indeed.
One interesting thing to note about this actress: her name is written in at least four different ways in Japanese. I found this out when I was out poster hunting. I thought the picture on the poster looked like Oka Naomi but I had to confirm this with the shop owner just to be sure.
Here are some examples: 丘ナオミ -- 丘奈保美 -- 岡尚美 -- 丘なおみ
