Should Airport Regulators De-clog Tokyo Narita International Airport?

Tokyo Narita International Airport (or just Narita International Airport) is Japan's second-busiest passenger airport, since it is responsible for most of the country's international traffic (both headed for Japan and coming from Japan.) It was formerly known as New Tokyo International Airport. As an air freight hub, it is the busiest in the country and third- busiest among the world's air freight centers. This international airport is categorized as a first-class airport, based on Japanese law. It should be differentiated from Tokyo International Airport, or Haneda Airport, which ironically does not manage much international passenger traffic for Japan. Tokyo Narita International Airport presently owns the longest runway in Japan, since its main runway spans 4,000 meters.
