        EnString = enString;
        JpString = jpString;
    }

    public override string Description {
        get {
            switch (CultureInfo.CurrentUICulture.Name) {
                case "en-US":
                    return EnString;
                case "ja-JP":
                    return JpString;
            }
            return EnString;
        }
