to make this function work you have to add following two lines above this function.

mb_language("Ja");
mb_internal_encoding("utf-8");

mb_convert_kana($_POST['something_value'], "rna");

I didn't find Japanese sorting function. 
(mb_sort_kana or something)
Only SJIS encoding treats hankaku kata kana,
 I can't post here copy & paste version script.
I'm sorry...
You will replace comments with appropriate japanese string,
and write exception handlings between lines as you like.

<?php
mb_internal_encoding("SJIS");

$moji = /*"aiueo...wawon -?.," <- serialized hankaku kata kana 50 on hyou goes here*/;
$moji .= "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxwz0123456789";

for($i = 0; isset($moji[$i]); $i++){
    $pittan[$moji[$i]] = $i;
}

function cmp($a, $b)
{
   if ($a == $b) {
       return 0;
   }
   return iter(mb_convert_kana($a, "askh") ,mb_convert_kana($b, "askh"), 0);
}

function iter($a, $b, $i){
    global $pittan;
    if(!isset($a[$i]) || !isset($b[$i])){
        return (isset($b[$i]))? -1 : 1;
    }
    if ($pittan[$a[$i]] == $pittan[$b[$i]]){
        return iter($a, $b, ++$i);
    }
    return (($pittan[$a[$i]]) < ($pittan[$b[$i]]))? -1 : 1;
}

echo "<pre>";
$arr = array(/*some japanese array here*/);
usort($arr, "cmp");
var_dump($arr);
?>

It seems that mb_convert_kana() doesn't convert symbols such as ' (single quoatation). It affected my program when I insert data into database. 

So, I've found 2 ways to solve this.
1) Use Javascript to convert those non-supported symbols before sending query string to your php page.
2) Use php function, str_replace $str, to replace those non-supported symbols. For example, $str = str_replace("'", "?", $str);
where the first single quot is half-width(han kaku), and the second one is full-width(zen kaku).
