The facility has two runways and covers 355 hectares (877 acres) of land. Fukuoka Airport is the principal airport on the island of Kyushu and is the fourth busiest passenger airport in Japan, serving 25 million passengers in 2018. The airport is surrounded by residential areas and subject to a curfew from 22:00 every night to 07:00 the following morning, at the request of local residents. The domestic terminal boasts extensive facilities, but the international terminal is located on the other side of the runway. The domestic terminal is connected to the city by the Fukuoka City Subway, and a subway from the airport to the business district takes about ten minutes. The international terminal is only accessible by road, although there is scheduled inter-terminal airport bus to the domestic terminal and the subway station, and scheduled bus service to Hakata Station and the Tenjin area.
