I've hit that glitch before. Maybe try making a Tk::Font object. Try to make a small example which demonstrates the problem. This displays Japanese for me. 
#!/usr/bin/perl
use warnings;
use strict;
use Tk;

my $mw=tkinit;

$mw->fontCreate('big',
     -family=>'arial',
     -weight=>'bold',
     -size=> 38
    );

my $string = "\x{65E5}\x{672C}\x{8A9E}\x{306E}\x{3072}\x{3089}\x{304C}
+\x{306A}\x{6F22 }\x{5B57}\x{3068}\x{30AB}\x{30BF}\x{30AB}\x{30CA}";

my $label = $mw->Label(-bg => 'white',
                       -text => $string, 
                       -font => 'big')->pack();

MainLoop;
