Gifu Airport — Gifu, Japan

QGU serves Gifu Airport in Gifu, Japan, a city in central Honshu known for its historic castle and traditional ukai cormorant fishing on the Nagara River. Gifu Airport has a mixed civil-military history, having previously handled scheduled commercial flights before those largely ceased, leaving the facility used mainly by the Japan Air Self-Defense Force and for general aviation activities. The airport sits near Nagoya, one of Japan's major metropolitan areas, which limits demand for separate commercial service given the proximity of Chubu Centrair International Airport. Gifu Airport's role today leans toward flight training, testing, and military operations rather than passenger traffic, reflecting a common pattern among Japan's smaller regional airfields overshadowed by nearby major hubs.
