1.Trends in Energy Consumption in the Transport Sector(Japan)v>

Energy consumption in the transport sector of Japan has increased constantly and, in particular, the increase by privately owned automobiles has been significant.
In the cargo sector, the use of railways has decreased while the use of trucks has increased significantly.

Energy Consumption by Means of Transport(Passengers)

Energy Consumption by Means of Transport(Cargo)

2.Causes of the Increase of Energy Consumption in the Transport Sector 1v>

Motorization began in Japan in the 1960s and ever since , demand for automobiles has increased rapidly and this trend continues today.
In response to this demand for automobiles, paved roads and expressways have been developed to cope with increased traffic.

Number of Automobiles and Length of Roads

3.Causes of the Increase of Energy Consumption in the Transport Sector 2v>

A significant cause of the increased consumption of energy by the transport sector is the increase of trasportation by automobiles that have a low unit ratio of consumption. The unit ratio of consumption of aircraft has improved and in recent years, is better than that of automobiles.

4.Factors for the Increase in Energy Consumption for Passenger Vehiclesv>

- The trend is mainly attributed to the increase in household ownership of passenger vehicles, increase of the total driving distance and increased vehicle weights offseting the fuel economy important.

Factors affecting energy consumption for passenger vehicles

Transition of passenger vehicle ownership per household

Transition of average vehicle weight owned

Source: Compiled by the Natural Resources and Energy Agency based on Automobile Inspection & Registration Association's automotive ownership data

5.Transition of Theoretical Mileage
and Actual Mileage of Gasoline Fueled Automobiles Stock(Japan)

While the theoretical mileage of owned automobiles deteriorated in the mid 1990s mainly due to the increased weight of automobiles in use, the level has been improving. Actual mileage is also showing an improvement trend.
