In 1960, when the Kansai region of the trade center was moved to Tokyo, the Japanese government at that time the airport was made there was made dizzy with complaints of residents who protested the sound noisy planes flying and landing because the airport was in the area Osaka buildings surrounded by residents of the Japanese government finally made the idea to create a floating airport


Initially, the airport is planned to be built near Kobe, but the city of Kobe refused the plan, so that the airport was moved to a location that is more to the south in Osaka Bay. In these locations could open the airport 24 hours a day, not like in the city. Man-made island, 4 km long and 2.5 km wide, has been proposed. Technicians needed to overcome a very high risk from earthquakes and typhoons (with storm surges up to 3 meters). Construction began in 1987. Sea wall was completed in 1989 (which is made of stone and 48,000 tetrahedral concrete blocks). Excavated three mountain for 21 million cubic meters of space. 10,000 workers and 10 million hours of work for 3 years, with 80 ships required to complete three hundred feet above the ground layer of the ocean floor and in the sea wall. In year 1990, three-mile bridge was completed to connect the island to the mainland in rinku-Town, at the cost of $ 1 billion. Completion of the artificial island of Osaka Prefecture increased only enough to move past the size of Kagawa Prefecture (Kagawa as the smallest left the area in Japan).
