Unanswered: Phone for reading/writing Japanese emails

Hi all,
Does anyone know of a phone from now or the last few years that supports Japanese? I know the iPhone does it no problem but that's out of my price range.
I'm looking for something reliable that my wife can use to keep in contact with her friends and family back in Japan.

Please let me know if you have any thoughts on what we can do.

Thank you,
JH
