Hi,
Go to the site
http://theweb.badm.sc.edu/kunshinim/ and download uwcjkstdtt.exe file.This exe is avaliable in many other sites too. Install this in your machine. Try to run this html page then.see whether you can able to see the japanese char displayed. Charset is case sensitive. so before u use different charset check for proper case.
<HTML>
<HEAD>
<TITLE>�V�_��������������</TITLE>
<META http-equiv="Content-type" content="text/html; charset=Shift_JIS">
</HEAD>
<body>
<td width="77" bgcolor="#99ccff" nowrap align="center">
<font lang="JA" size="2" color="#000000">
�s��������</font></td>
<input type=text name=txt value=''>
</body>
</html>
