The Asia-Pacific region is expected to grow into the largest aviation market worldwide in 2025. The capacity of airports in the Tokyo metropolitan area, which was a bottleneck in Japan’s aviation policy for many years, has been significantly expanded, with the number of departures and arrivals at Haneda now 447,000 per year and at Narita 300,000 per year. The Japanese aviation policy, which currently emphasizes the balanced development of national land under the condition of capacity constraints, should be drastically shifted toward a competitive policy with emphasis on enhancing international competitiveness.
