read emails in Japanese on cell phone

Jamie,

I don't know of any Japanese character set that you could install into
your current email software, however iCJKMail is a java application
that may be just what you are looking for. It would allow you to view
Japanese emails that you receive to your IMAP or POP3 email accounts. A
free 14-day trial is available at www.icjk.com.

Let me know what you think!
