Tokyo's Haneda airport will undergo a major renovation to prepare for the surge in flights expected for the 2020 Summer Olympics, officials at the transport ministry said.
Terminal 2, which is used mainly for domestic flights by All Nippon Airways, will be renewed to install immigration, customs and quarantine facilities for international travelers.
It will also host new duty-free shops and lounges and see some of its gates designated for international flights. A detached supplementary boarding area for domestic flights will be built in an area to the north that is now used for parking aircraft.
The international terminal will be renamed Terminal 3.
Part of Terminal 1, which is used chiefly by Japan Airlines, will be redesigned with rental offices, lounges and an indoor golf driving range, officials from the Land, Infrastructure, Transport and Tourism Ministry said.
The parking area will meanwhile be expanded to fit 500 more cars.
Under government plans, Haneda, also known as Tokyo International Airport, will be given up to 39,000 more flight slots a year on top of its current 447,000 by the 2020 Olympics, mainly by establishing new approach routes over central Tokyo.
