It would be a bit cheesy for a character who is not Japanese though, quite a reminder of those people who go off and get tattoos of japanese characters not knowing what they mean just because they think they are cool.
I have a bunch of pet peeves and this one is near the top of the list.
They pick one out of a book which stands for something; usually one word, which they could have just put in English. If they wanted someone to be able to read it, that's what they would have done. Instead, they have to assume the book was accurate and instead of people being able to read it, they have to explain it to every person who wants to know (which probably isn't many.) So it really doesn't matter what it says, it just comes down to "it looks cool".
If I see something that looks cool, I say "hey, that looks cool". Apparently if they see something that looks cool, they say "hey, I want to deface my body with that image for the rest of my life".
Actually, I think I may hate tribal tattoos more. I don't know, they're both god awful.
Oh yes, oh yes. Watch out or they'll put a tattoo saying "gaijin" (foreigner) on you. I've seen it happen.
Wouldn't they recognize that it's not the symbol they chose?
But regardless, like I explained above, it really doesn't even matter. No one they ever meet will be able to read it, and it may even look "cooler" than the stupid one they chose to begin with.
