The transport ministry estimates that a planned fourth runway at Tokyo's Haneda airport will add 1.2 trillion yen to the economy of the metropolitan area the year it is completed, ministry officials said Tuesday.
The runway is also scheduled to be used for international flights. When it is completed -- the target date is 2009 -- it should help increase the number of arrivals and departures at the airport to 360,000 a year, up from the current 270,000, according to calculations by the Land, Infrastructure and Transport Ministry.
The increased use of the airport will boost sales at airlines and airport-related businesses by about 600 billion yen, the ministry estimated.
