  Japan has invested heavily in transportation infrastructure since the 1990s. The country has approximately 1,200,000 kilometers (750,000 miles) of roads made up of 1,000,000 kilometers (620,000 miles) of city, town and village roads, 130,000 kilometers (81,000 miles) of prefectural roads, 54,736 kilometers (34,011 miles) of general national highways and 7641 kilometers (4748 miles) of national expressways as of 2017.
  
  Since privatization in 1987, dozens of Japanese railway companies compete in regional and local passenger transportation markets; major companies include seven JR enterprises, Kintetsu, Seibu Railway and Keio Corporation. The high-speed Shinkansen (bullet trains) that connect major cities are known for their safety and punctuality.
  
  There are 280 airports in Japan as of 2025. The largest domestic airport, Haneda Airport in Tokyo, was Asia's second-busiest airport in 2019. The Keihin and Hanshin superport hubs are among the largest in the world, at 7.98 and 5.22 million TEU respectively as of 2017.
