i'm italian, and i would to translate the phrase "buon onomastico"-"good
onomastic" or -" good name day" into japanese.
i don't know how to write that.
and i have made a greeting card for my friend in which is a clipart who will
say
"wow! what happiness! i'll became japanese!!!"

how can i say that in japanese? I must write these phrases in kanji but if
you could me write romaji too, you will me do a pleasure ;)
(i hope you have understand my english!)
kisses and thanx!!!!
