[1] Passenger railway usage and density is lower than that of Greater Tokyo or Greater Osaka, as generally the trend in Japan, few free maps exist of the entire network, operators show only the stations of their respective company and key transfer points.
Most local bus routes complement existing rail service to form an effective intermodal transit network.
However, with the just-in-time requirements of automobile manufacturers and suppliers regional airports also handle much cargo.
