The invasion of the yellow fever mosquito <i>Aedes aegypti</i> at Narita International Airport, Japan was detected for the first time. During the course of routine vector surveillance at Narita International Airport, 27 <i>Ae. aegypti</i> adults emerged from larvae and pupae collected from a single larvitrap placed near No. 88 spot at passenger terminal 2 on August 8, 2012. After the appearance of <i>Ae. aegypti</i> in the larvitrap, we defined a 400-m buffer zone and started an intensive vector survey using an additional 34 larvitraps and 15 CO₂ traps. International aircraft and passenger terminal 2 were also inspected, and one <i>Ae. aegypti</i> male was collected from the cargo space of an international aircraft from Darwin via Manila on August 28, 2012. Larvicide treatment with 1.5% fenitrothion was conducted in 64 catch basins and one ditch in the 400-m buffer zone. Twenty-four large water tanks were also treated at least once with 0.5% pyriproxyfen, an insect growth regulator. No <i>Ae. aegypti</i> eggs or adults were found during the 1-month intensive vector survey after finding larvae and pupae in the larvitrap. We concluded that <i>Ae. aegypti</i> had failed to establish a population at Narita International Airport.
