As far as transportation of the mail is concerned, that's true, it's all 
7-bit.  However, the MUA has to interpret the bytes as either JIS or 
US-ASCII.  The Content-Type header can be used to specify JIS for the 
body of the mail but the headers will be interpreted as US-ASCII unless 
specified otherwise.  The only way to specify the actual character 
encoding of the headers is to base64 encode them.
