US military bases in Japan face severe infrastructure decay

A report from the Department of Defense Office of Inspector General has revealed severe infrastructure deterioration and safety hazards at several U.S. military bases in Japan. Following an audit of 11 Pacific Command bases, investigators identified widespread issues including chronic mold growth, asbestos, lead-based paint, and failing water pipes.

Specific locations such as Camp Courtney, Kadena Air Base, and Yokota Air Base were highlighted for significant structural failures. Findings include visible corrosion, crumbling walls, concrete spalling, exposed rebar, and water intrusion. At Kadena, investigators documented buildings with cracked pillars, holes in aircraft hangars, and a 50-year-old water pipe with a 12-foot crack.

The report notes that these conditions pose ongoing risks to the health and safety of service members and their families. In some areas, falling debris—ranging from small fragments to large slabs—presents a direct danger to personnel. The deterioration affects both mission-critical communications infrastructure and essential living quarters, prompting calls for urgent renovations and revised maintenance protocols.
