Yokota Air Base — Fussa, Japan

Yokota Air Base, coded OKO, is a major United States Air Force installation located in Fussa, in the western Tokyo metropolitan area of Japan. As the headquarters of U.S. Forces Japan and the 5th Air Force, Yokota plays a central role in American military presence in the Asia-Pacific region, hosting airlift, command, and control operations. The base is not open to commercial civilian air traffic and instead functions purely as military infrastructure supporting U.S.-Japan defense cooperation. Yokota has periodically been the subject of local discussions regarding noise and potential joint civilian use, though it remains predominantly a military facility. With its strategic location near Tokyo, OKO serves as a key logistical hub for American military operations throughout the broader Indo-Pacific theater.
