Happy Birthday Miura! 
I'm more interested with how you got his address!
I concur. From what I understand, Mr. Miura would be awfully secretive about that stuff, considering he didn't want people to see him in that DVD interview. :x
But I don't know what I'd get him for his birthday. A juicemaker, maybe?

Or perhaps one of those spiffy Berserk watches from Art of War!
