You need to be sure to set the character set when you set the content. The following example demonstrates. The message content is the numbers from 1-10.

import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;

public class SendJIS {
  public static void main (String args[]) throws Exception {
    String host = args[0];
    String from = args[1];
    String to = args[2];

    // Get system properties
    Properties props = System.getProperties();

    // Setup mail server
    props.put("mail.smtp.host", host);

    // Get session
    Session session = Session.getInstance(props, null);

    // Define message
    MimeMessage message = new MimeMessage(session);
    message.setFrom(new InternetAddress(from));
    message.addRecipient(Message.RecipientType.TO, 
      new InternetAddress(to));
    message.setSubject("Hello JIS JavaMail");

    String jisText = 
      "u4E00u4E8Cu4E09u56DBu4E94u516Du4E03u516Bu4E5Du5341";

    message.setContent(jisText, "text/plain; charset=JIS");

    // Send message
    Transport.send(message);
  }
}

For some reason this only displays 1-6 okay as far as the content. I don't know why 7-10 is messed up. As I don't use Japanese that much, it could be my configuration.
