question about how to write a phrase in Japanese characters
 

Hi, I am helping make some bracelets for the Japanese relief effort but I don't actually know Japanese so I am wondering if any of you can let me know how to write "Japan is in our hearts" in Japanese characters. I would really appreciate it! Thanks

TBH, I am not sure why you want this in Japanese when you or your buddies cannot even read the language. If you insist, however, the following would be one idea.

日本の事を思っています

日本は僕たちの心にあります

If people want to make this a guessing game, I'm out. Where is the need to specify the speaker's gender?

日本は私たちの心にあります。

Yesterday I heard a female referring to herself as 俺 in Koebu.
