you still do not have support for Japanese characters. In this case please follow instructions below to enable Japanese language support:
Windows 95, 98, ME and NT
Your system should offer to download Asian fonts by default while viewing pages in those languages, just as long as you're using Internet Explorer.
Otherwise, update your system manually with these language support packs: Microsoft Global IME (Input Method Editor) 5.02 for Windows 95, 98, and NT 4.0
Windows 2000
Windows XP and Server 2003
The Windows CD-ROM is needed while installing support for East Asian languages. (Non-East Asian localizations only)
Instructions for Windows XP and Server 2003
Windows Vista
Windows Vista includes proper support for Japanese characters by default. You can actually type in Japanese or view Japanese with the default tools.
Mac OS X
By default all necessary fonts and software are installed in all versions of Mac OS X from 10.2 (2002) and higher.
For Mac OS X 10.1 multilingual software updates are available as free downloads from Apple's website. The Asian Language Update will install support for Chinese, Japanese and Korean.

As of Fedora Core 4, you need fonts-chinese, fonts-japanese and/or fonts-korean.
