  Tokyo has the lowest car ownership rate among all prefectures in Japan, with 0.416 cars per household compared to the national average of 1.025 per household. This is despite Tokyo being one of the most affluent areas in the country, with a nominal GDP per capita of around US$75,000. A 2021 survey found that 81% of respondents without a car were satisfied with public transport and saw no need to own one.
  
  Each road in Tokyo falls into one of the following categories depending on the type of ownership: private roads, municipal roads, metropolitan roads, and expressways. As of April 1, 2022, the total length of roads in Tokyo is approximately 24,741 km (including 2,370 km of metropolitan roads), with a total area of approximately 190.31 km 2 (including 46.30 km 2 of metropolitan roads). Intercity expressways in and around Tokyo are managed by NEXCO East, while expressways that serve only within the Greater Tokyo Area (Shuto Expressway) are operated by the Metropolitan Expressway Company. Tolls are collected based on the distance travelled. The total length of the Shuto Expressway is 337.8 km, with speed limits usually set at 80 km/h or 60 km/h to reduce noise pollution and accommodate the relatively winding road shapes.
