美亜対美矢？ Mia or Miya?

Mia is my nickname, I have been called it since the day my younger sister could speak. I didn't use it much with my friends until recently. I used to reserve it to only a family thing. Recently I have decided that for some it is just easier to tell them that Mia is my name, because then they can say it correctly. Plus it's cute, and I'm cute! ^_^ I was very sick of hearing 'May' in Bakersfield, it wasn't something I respond to. Mia is just me! I still respond to Melia and whichever mis-pronunciations that come about. That's what you get for having a kid with a name that's not english, right? (And I am thinking of giving my kids Japanese names...) Heh well I wonder what my parents would have named me if they didn't come to Hawaii. My sister got to be named after some male relative named Nicholas, and I was suppossed to be Malia which was Hawaiian for Mary, after some great aunt of mine. Well they slightly changed it (Melia means Plumeria - the most common flower used in leis) and the rest is who I am. Well now that I am going by Mia alot more I decided that it is much better to use Mia as my Japanese name, since there are no "l's" in Japanese. May-ria sounds a little silly, just another way to say my name wrong. [Don't worry peeps! I don't seriously get mad at anyone who says my name wrong unless they are doing it to annoy me!] But Mia sounds smoother and sounds like I am Japanese. :) Well one of my Japanese friends here spelled my name as "Miya" and I thought that was uber cute! Sounds exactly the same too! My dilemna comes with the matter of kanji. 美亜 (Mia) means "Beautiful Asia". Sounds a little strange to me, I aint really Asia... I've been using that one for now but I am wondering if I should consider a change... 美矢 (Miya) means "beautiful arrow"... that sounds cuter. But then again it's not necessarily a matter of how cute I am, right? :P Both kanji's are easy for me to write. I don't think Japanese people place huge importance on what a name literally means. Just wondered what some people would think. (Yes I think about silly and useless things at 1am)
