Setting the language of a man page

[Antony Stace <antony@example.com>]

 Hi Folks

I have just installed Redhat Linux 7.0 Japanese version.  I have it
configured so that when it boots ot goes to the GUI login screen.  When
I log in I choose English as the language.  All the icons on the
desktop,Gnome Applications and Netscape come up in English, however when
I do a 

$man <command name>

I get garbage, its not even in Japanese when inside a kterm.  What do I
have to set so that I get English man pages.

Cheers

Antony
