Xcalendar is a simple calendar for your desktop that can be used to take short memos in Japanese.
There are two copies of the applications defaults files.
One copy is in /usr/X11R6/lib/X11/app-defaults/. The
other file is
/usr/X11R6/lib/X11/ja_JP.EUC/app-defaults/XCalendar.
In my .bash_profile I set my
language environmental variable as shown below.
$ export LANG=ja_JP.EUC
