Typhoon No. 21 Aerial view at Kansai Airport, runway still flooded overnight after Typhoon No. 21.

Early in the morning of May 5, activities began to rescue by boat and bus approximately 3,000 travelers who had been isolated on the Kansai Airport island due to Typhoon No. 21, which swept through Shikoku and the Kinki region on May 4. At Kansai Airport, almost all of Runway A (3,500 meters long) and the tarmac on the first phase island were flooded with up to approximately 50 centimeters of water due to seawater flowing in from the high tides. Machinery rooms and other facilities in the basement of the Terminal 1 building were also flooded, resulting in power outages in some areas. The runway remains flooded overnight after Typhoon No. 21.
