Shuto Expressway
 Shuto Expressway (首都高速道路 Shuto Kōsoku Dōro lit. Metropolitan Expressway) is a network of toll expressways in the Greater Tokyo Area of Japan. It is operated and maintained by the Metropolitan Expressway Co. Ltd. (首都高速道路株式会社 Shuto Kōsoku Dōro Kabushiki-gaisha). Most routes are grade-separated (elevated roads or tunnels) and central routes have many sharp curves and multi-lane merges which require caution to drive safely.
