Which city is represented by the airport code NRT?

The airport code NRT stands for Narita International Airport, which is located in Japan, specifically serving the Greater Tokyo Area. This airport is one of the primary international gateways to the Tokyo metropolitan area and is well known for handling a significant amount of international air traffic. Its significance as a major hub in Asia supports its representation by the code NRT.

In contrast, the other options pertain to different locations and do not relate to the airport code in question. For instance, NNR does not correspond to any major international airport commonly recognized, while Nairobi is served by the airport code NBO (Jomo Kenyatta International Airport). Tegucigalpa, Honduras is represented by the airport code TGU. Hence, the identification of NRT with Tokyo, Japan, is accurate and reflects a specific location significant in the context of international travel.
