Bah, nothing like having a Japanese partner to kill of the shyness, you really learn how to have a good fight in Japanese!
.
Kidding, we fight in English!. ☝
As other have said, try and talk to her as a normal everyday girl from your area, and be friends, and just try and avoid the japan thing, if she thinks you just like her because she's Japanese then she wont be interested and if you just want to talk to her because she is Japanese then you'll never make anything more the a passing "oh, hi" kinda friendship.
japanese people are infinitely more interesting when you get to know them as people rather then nationality.
As a bit of a gamer on my free time sometimes i'll come across the odd japanese/japanese origin person who speaks English, in a server, and maybe get hounded by some Yugioh fans, and when we talk they ussually mention the one thing that bothers them is some folk can be all over them for their natinoality and its a bit annoying when, just like me and others, he's just there to enjoy some free time gaming and chatting.
Just talk to her like any normal person, and try and be friends, and forget the "OMFG she's japanese!" feeling, if you can beat that then you'll earn a good friend and still get to learn about japan in the process.
Good luck!.
