When I switch to Japanese locale in Windows XP SP2 English the System font indeed does have Japanese script but also does contain the Japanese glyphs.
I'm getting tired of repeating the same things again and again. System font does not contain Japanese glyphs, what you see is a result of font linking (to a font existing in WIndows but missing in Wine).
At least when the System font is used to write Japanese text in Notepad it is displayed correctly, unlike in Wine.
And the reason has been explained already.
