One of two international airports serving the Greater Tokyo Area, the other one being Narita International Airport.
In 2010, a dedicated international terminal, currently Terminal 3, was opened at Haneda in conjunction with the completion of a fourth runway, allowing long-haul flights during night-time hours.
Airlines in Japan strategize Haneda as "Hub of Japan": providing connections between intercontinental flights with Japanese domestic flights, while envisioning Narita as the "Hub of Asia" between intercontinental destinations with Asian destinations.
