Hi Aki11
I think you'll find *many* people on this site who are interested in Japanese and helping you improve your English.
Anyway, I'm from the East Coast of America and would certainly be willing to talk with you over e-mail or skype. I took Japanese all through college, but it's been 3 years and I've forgotten an awful lot and could use some practice too. Send me a private message with your e-mail address if you're interested in talking
