Narita International Airport is an international airport located in Narita, Chiba, Japan, in the eastern portion of the Greater Tokyo Area.

Narita handles the majority of international passenger traffic to and from Japan, and is also a major connecting point for air traffic between Asia and the Americas. It is the second-busiest passenger airport in Japan, busiest air freight hub in Japan, and third-busiest air freight hub in the world. It serves as the main international hub of Japan Airlines and All Nippon Airways, and as an Asian regional hub for Northwest Airlines and United Airlines. Under Japanese law, it is classified as a first class airport.

The airport was known as New Tokyo International Airport until 2004. While Tokyo is the source of much of Narita Airport's traffic, the airport is located far from central Tokyo (1 hour by the fastest train) and in a different prefecture. Tokyo International Airport (Haneda Airport), located in Tokyo proper, is the busiest airport in Japan and the fourth-busiest in the world, even though it handles very little international traffic.
