OK, What you need is the Windows IME (Input Method Editor) for Japanese.
The Follow two are designed for 9x/Me/Nt4 and once installed will allow you view the moon language in all its weeaboo glory.

Do NOT install both - Install only first if you have winme without office xp (ie. no msoffice or <2000) or the Second if you have Office XP installed. NOT BOTH.
