The Shuto Expressway (首都高速道路) is a network of Tolled expressways in the Greater Tokyo Area of Japan. It is operated and maintained by the Metropolitan Expressway Company Limited (首都高速道路株式会社). Most routes are grade separated and have many sharp curves and multi-lane merges that require caution to drive safely. The speed limit is 60 km/h on most routes, 80 km/h on the Bayshore Route, and 50 km/h on the Inner Circular Route. As of 2014, the cash toll for a standard-size car is ¥1300 regardless of distance traveled. Vehicles using the ETC toll-collection system pay a distance-based toll ranging from ¥300 to ¥1300 for ordinary vehicles (see toll price) – in some cases substantially less than the previous fixed-rate toll. Lower cash rates exist for certain radial routes (where there are only a few kilometers of expressway remaining) and ETC users have various time-of-day discounts. For large vehicles, the toll is doubled.

History

The Metropolitan Expressway was first built between Kyobashi Exit in Chūō, Tokyo and Shibaura Exit in Minato, Tokyo in 1962 for the purpose of increasing traffic flow efficiency in the Tokyo Metropolitan Area, thus optimizing and improving the functionality of the traffic system. Since then, 280 kilometers of highway network has been built in the Tokyo metropolitan area; 30 kilometers more of highway are either constructed or planned, making the Metropolitan Expressway a vast network of urban expressways in the Tokyo region. Like other expressways in Japan including the Tōmei Expressway, the Shuto line has become a common street racing road. One of the lines, the Bayshore Route (also known as the Wangan route), received worldwide notoriety during the 1990s as the home course for the Mid Night Club, one of the most notorious street racing clubs, who were known for their 300 km/h, sometimes 320 km/h exploits. These exploits and street racing culture on the Shuto Expressway have made it a well-known location for street racing and speed records. Due to this infamy, the Wangan is the setting for several entertainment franchises, such as the manga and arcade game Wangan Midnight, video games Shutokou Battle and Gran Turismo 5, 6, Sport and 7 (as the street circuit) and the movie series Shuto Kousoku Trial. Numerous car enthusiast magazines and DVDs, like Best Motoring, also highlight races and activities on the Wangan. Inner Tokyo sections of the expressway prohibit motorcycle pillion passengers due to poor road geometry. The C2 route allows motorcycles with pillion passengers to travel through. The ban does not apply to motorcycles equipped with a sidecar. The segments with a pillion ban include the important C1 Inner Circular route and adjoining central Tokyo routes. There are 21 parking areas scattered throughout the Shuto Expressway system. In general these are much smaller than the service areas available every 30 km or so on inter-city expressways.
