Naval Air Facility Misawa, located at Misawa Air Base in Aomori Prefecture on the northern tip of Honshu, Japan, served as a joint US Navy and Air Force installation throughout the Cold War era. The facility’s position on the northwestern Pacific coast of Honshu made it particularly valuable for monitoring Soviet naval and military activity in the Sea of Japan, the Soviet Far East, and the northwestern Pacific. Navy patrol aviation and P-3 Orion ASW squadrons operated from Misawa conducting North Pacific and Sea of Japan patrol missions monitoring Soviet submarine movements and naval activity. The Cold War-era construction of NAF Misawa’s aviation and support facilities used asbestos-containing building materials in the hangars, maintenance shops, and support buildings consistent with military construction specifications of the period. Navy personnel stationed at Misawa accumulated asbestos exposure from this Cold War facility construction throughout their Western Pacific duty assignments.
