Japan didn’t have enough room for this airport–so they built an island!
Japanese engineering never fails to amaze, and their airports don't let down either.
Kansai International Airport is situated on an artificial island in the middle of Osaka Bay just southwest of Osaka Station and services some major areas. If you can't find space to land your planes, build one in the middle of the sea!
It opened on September 4, 1994 to alleviate the overcrowding at Osaka International Airport, which currently only handles domestic flights.
In 2006 it handles 116,475 aircraft movements, 73,860 of which were international. It serviced 16,689,658 passengers, 11,229,444 which were international travelers.
When originally planning to build the island earthquakes, typhoons and storm surges were a big concern. The island was finished in 1989 thanks to 10,000 works and 10 million work hours over three years. A bridge was constructed in 1990 to connect the island to the main land for an impressive $1 billion.
Since construction of the airport, the island has sank 8.2 meters from the weight of the construction material. It easily became the most expensive civil works project in modern history.
