The high cost of using Narita International Airport continues to draw criticism from airlines.

Narita's landing fees, which account for the bulk of that cost, are more than double the fees at South Korea's Incheon Airport and Singapore's Changi Airport, which are competing for the title of Asia's main air travel hub.

Narita International Airport Corp., which runs Narita airport, has tried to justify its high fees by citing its huge debt load, a legacy of cost overruns from its construction. As of the end of March 2012, the company was saddled with ¥666.2 billion in debt.
