It's very hard to read if menu is localized to Japanese for something like appletviewer or Hotjava.
Especially menu label is in Kanji then Kanji font gets squashed. It is ridiculous

Currently default font used for Menu is MS gothic 8pt, however System recommendation is MS P gothic 9pt or 12pt. Most of Win32 native application follows that manner and can be dynamically changed at system level
(Switch between Big or Small font).

Since Kanji has many strokes than Alphabet and more complicated, some kanji may
not be read at all. So that it is RECOMMENDED to change a default font size
for Japanese locale.
