Ministry of Land, Infrastructure, Transport and Tourism announced on August 8 that new air routes over the center of Tokyo into Haneda Airport will be in operation on March 20 2020 to increase international flights from/to the airport. The new routes are expected to allow the airport capacity to expand from about 60,000 slots a year today to about 99,000 slots a year.
Placing expansion of the Haneda and Narita airport functions as one of the top priorities toward success of Tokyo 2020, the ministry aims to add about 80,000 slots a year for both of the airport in Tokyo.
