Japan Trains during Rush Hour

In Japan, share of rail transportation is high and use of automobiles is restrained consequently. Rail transport accounts for 27 percent of all passenger transport in Japan. Namely, in Greater Tokyo Area and Keihanshin metropolitan area, railway has dense network and frequent service, and accounts for more than half of passenger transport, and majority of people there commute by public transport without using their cars.
Railway in Greater Tokyo Area has severe congestion. It is gradually being improved by increasing the capacity of rail and expansion of Home Liner and bi-level Green car (First-class) increases the chance to commute with comfortable sheet paying additional supplement. But it is still common in major lines of Tokyo that more than 3,000 passengers packed in a 10-car train and about 100,000 passengers are transported in an hour (Usually, maximum capacity of double-track commuter rail in Japan is 10-car trains, 2 minutes interval) and presumably one of the most congested railways in the world.
In road transport, Expressways of Japan is operated by beneficiaries-pay principle and imposes expensive toll fee, and it also has an effect to reduce road traffic. Electronic toll collection (ETC) is widespread and discount in unoccupied midnight is introduced to disperse traffic without concentrating in rush hour. Road pricing is being considered but currently not introduced, partly because expressway fee is already very high.
The expressways in Japan from 7am to 9am are usually so congested and full that people are hired to shove or stuff people who will not wait till the next train. Trains are widely used in Japan due to the small amount of land and high population. It's actually kind of weird when you go to Japan and see people pushing and squishing an already packed train car. There are videos on youtube if you feel more interested in seeing how this is done. Honestly it is perfectly normal in Japan when this is done. Hope I was informative.
