If I'm not mistaken, the email standard specifies that only 7-bit ASCII-
encoded bytes can be transported safely and reliably. The highest bit may 
be stripped by email server or client. Thus, to transport non-ASCII data 
safely, they cannot use "regular" encodings (e.g. utf-8, shift-jis, etc). 
I'm not sure what the standard is for Japanese character, but it seems 
that from reading the email header, the encoding used is a modified 
UTF-8. Try checking python's email module, they might have something for 
decoding 7-bit email-utf to 8-bit regular-utf or unicode string.

After decoding the email-utf to regular-utf or unicode string, converting 
to other encoding should be trivial.
