I don't think you understand what I'm asking for. You talk to a woman you've never seen before on the street. I thought that was was pickup was?
What you do use for the word "you" ?
I often start conversations referring to: what she is wearing (to include her nails, shoes, or relating to fashion), something about or going on around us (ex- advertisement picture, some event), or asking a question about culture or language.
The emphasis would be on the subject of the conversation. "Wow, those are nice shoes. You have good fashion sense. Did you buy those shoes in Japan or overseas?"
The conversation doesn't start as "Hey, you!" She is not referred to in any unusual or different way, then how you normally talk to people.
As Sudsy mentioned, "you" or "anata" is usually removed from Japanese sentences. However, you can include it, to make what you are saying more clear or prevent a misunderstanding.
After starting a conversation, you can segue into introducing yourself and asking her name. "I'm new to Japan, and like Tokyo fashion styles. By the way, my name is John, what is your name?"
So, early on in the conversation, you can know her name. You would proceed in the conversation, where you learn more about her, and tell her more about yourself.
