Passenger Transport by Mode, Japan, 1950-2005
The evolution of passenger transportation in Japan over the last 50 years reveals that the number of passenger-km has increased substantially and that the modal share of movements has shifted to the automobile. The automobile accounted for 60% of all passenger-km in Japan for 2005. This represents a shift from collective and inflexible modes (railways and buses) to individual travel. Both trends are related to demographic growth (in the 1960s and 1970s) and especially to growing income levels (in the 1980s and 1990s). The growth of domestic air transportation in Japan is particularly linked with this trend. Japan represents a case point of a modal and mobility transition on par with its economic development.
