七十年代以来,随着运输结构的变化,铁路在交通运输中独占的地位已不复存在。东京至北海道的旅客运输,已有90％利用航空。铁路在国内货物运输中的比重,按吨公里计也不超过10％。近距离旅客运输也有向汽车转移的可能。日本民航是1945年下半年恢复的,东京一大阪间515.4公里,需飞行3小时,一机只能乘8人,运费也很贵。1960年以后,将活塞引擎机更换为涡轮螺旋浆飞机,一机乘客高达500人,遂使国内航空形势为之一变,使航空的安全性、舒适性、快速性都有很大提高。由于民航飞机的大型化,也降低了成本。过去二十年间,飞机票价上调1.7倍,而日本国铁票价上调4倍,这就使飞机票价与铁路票价相较,由绝对高转为相对高,现在是相对低了。
Since the 1970s, as the structure of transportation has changed, the exclusive status of the railway in transportation has ceased to exist. Passenger transport from Tokyo to Hokkaido, 90% of the use of aviation. The proportion of railways in the domestic transport of goods does not exceed 10% by tonne of kilometers. Passenger transport also has the possibility of moving to the car. Japan’s civil aviation was restored in the second half of 1945, with 515.4 kilometers between Tokyo and Osaka. It required 3 hours of flight, and only 8 passengers per flight can be used. The freight rate is also very expensive. After 1960, replacing the piston engine with a turbo propeller plane, with a single passenger capacity of 500 passengers, the domestic aviation situation was changed. As a result, aviation safety, comfort and speed were greatly improved. As the large-scale civil aircraft, but also reduce the cost. In the past two decades, the fare of airplanes has been raised 1.7 times and that of Japan Railways has been raised four-fold. This has resulted in relatively low air-to-rail fares from absolute highs to relatively low fares.
