The Gateway goes behind the scenes of the world's major transport hubs, revealing the logistics that keep goods and people moving. This month, the show is in Tokyo, Japan.
(CNN) -- In Japan, rail rules as the transport mode of choice with over 2,000 kilometers of railroad tracks and an estimated 24 million passengers using the network every day, according to Japan's rail companies.
Despite the country's land mass being roughly the same size as the state of California, the Japanese have developed an extensive railway network that provides easy access to larger cities from smaller towns in the country.
One of the reasons Japan's railway network is so popular is the commuter traffic. Stations are extremely busy during peak periods and some operators even hire "oshiya" or "pushers" -- train and subway staff who help facilitate getting commuters onto trains.
