Run ajax request on document.ready jquery

Ajax 

$(document).ready(function() {
    $.ajax({
        type: 'POST',
        url: '../include/ListOfCities.php',
        dataType: "json",
        data: {
            Country: "Japan"
        },
        success: function(data) {
            console.log(data);
            var city = ('#city');
            $(city).empty();
            for (var i = 0; i < data.length; i++) {
                $(city).append('<option id=' + data[i].sysid + ' value=' + data[i].city_name + '>' + data[i].city_name + '</option>');

            }
        }

    });
});

php

$country = mysql_real_escape_string($_POST['Country']);
$stmt = $dbh->prepare("SELECT * FROM city_tbl WHERE country_name = ? ");
$stmt->bindValue(1, $country, PDO::PARAM_STR);
if ($stmt->execute()) {
    if ($stmt->rowCount() > 0) {
        while ($selected_row = $stmt->fetch(PDO::FETCH_ASSOC)) {
            $citylist[] = array('sysid' => $selected_row['sys_id'], 'code' => $selected_row['city_code'], 'name' => $selected_row['city_name'], 'parentid' => $selected_row['parent_id']);
        }
        $input = array_map("unserialize", array_unique(array_map("serialize", $citylist)));
        echo json_encode($input, JSON_UNESCAPED_UNICODE);
    }
}

I want to display the all the city in japan in a select option menu i want to load the cities when the page loads i am sending the ajax request like above but i don't get any result the ajax above works fine when i use it on button.

Just try setting async:false in your ajax request. So the final code will be 

$(document).ready(function() {
    $.ajax({
        type: 'POST',
        url: '../include/ListOfCities.php',
        dataType: "json",
        async:false,
        data: {
            Country: "Japan"
        },
        success: function(data) {
            console.log(data);
            var city = ('#city');
            $(city).empty();
            for (var i = 0; i < data.length; i++) {
                $(city).append('<option id=' + data[i].sysid + ' value=' + data[i].city_name + '>' + data[i].city_name + '</option>');

            }
        }

    });
});
