New Chitose Airport (CTS)

New Chitose Airport is an airport located 5.0 km south southeast of Chitose and Tomakomai, Hokkaidō, Japan, serving the Sapporo metropolitan area. By land area, it is the largest airport in Hokkaidō.

It is adjacent to Chitose Air Base, a Japan Air Self-Defense Force base which houses F-15 Eagle fighter jets, the Japanese Air Force One government aircraft and a number of smaller emergency response aircraft and helicopters. Chitose and New Chitose have separate runways but are interconnected by taxiways, and aircraft at either facility can enter the other by ground if permitted; the runways at Chitose are occasionally used to relieve runway closures at New Chitose due to winter weather. JASDF provides air traffic control for both facilities.

As of 2005, New Chitose Airport was the third busiest airport in Japan and ranked #64 in the world in terms of passengers carried. The 894 km New Chitose - Tokyo Haneda route is the busiest air route in the world, with 8.8 million passengers carried in 2010.
