Background for the establishment of the Kansai International Airport
With the start of use by jet aircraft in June 1964, the noise problems for the Osaka International Airport (Itami Airport) became more severe, the people living around the airport went to court to stop flights at night, to abolish Osaka International Airport, etc., and arbitration in regard to the pollution adjustment committee etc. started.
Countermeasures against the occurrence were taken, like limitation of night flights, introduction of large aircraft with low noise (Air Bus), etc., and moving compensation, soundproofing of housing, and other measures were advanced, while on the other hand the insufficient transport capacity of the Osaka International Airport because of operation limitations etc. became more severe.

In this situation, the Airport Council in 1974 investigated and evaluated the three proposed locations off the coast of Senshu, off the coast of Kobe, and on the Harima sea and judged that the Senshu location is the most desirable one.

On receiving this report in 1981, the Transport Ministry (the present Ministry of Land, Infrastructure and Transport) presented the so-called "Troika" set of 'Plan for the Kansai International Airport', 'Plan for evaluation of the environment influence of the Kansai International Airport', and 'Philosophy for the preparation of the location for the Kansai International Airport', and after the three districts agreed in 1984, a detailed work assessment was implemented by the Kansai International Airport Co., Ltd., which was established as the main body for construction and operation of Kansai International Airport.
For the construction work, suitable environment protection measures were implemented so as not to influence the environment of the surrounding sea etc., an environment monitoring system was established, and efforts towards environment creation were made by construction of seaweed banks etc.

This airport on the sea, with no aircraft noise pollution and mild to the environment, came into existence in this way.
