map postal.get_address(string first_three, string second_four)
{
    this_address = map();
    first_three_len = ifnull(input.first_three,"").length();
    second_four_len = ifnull(input.second_four,"").length();
    if ((first_three_len  ==  3)  &&  (second_four_len  ==  4))
    {
        postal_code = input.first_three + input.second_four;
        data_url = "https://raw.githubusercontent.com/aorborc/jp_code_english/0804e74d63ec902eccfcf847ea49a0a6a7488d16/data/" + input.first_three + ".js";
        str = getUrl(data_url);
        value_map = str.toMap();
        my_map = (value_map.get(postal_code)).toMap();
        jp_address = ((my_map.get("perfecture_jp")) + my_map.get("jp_add_1")) + my_map.get("jp_add_2");
        eng_address = ((my_map.get("prefecture")) +" " +  my_map.get("city")) + " " +  my_map.get("town");
        this_address.put("jp_address", jp_address);
        this_address.put("eng_address", eng_address);
