AGP Corporation provides essential infrastructure and operational support services to airports across Japan. Its core activities include delivering vital utilities—such as electricity, air conditioning, and compressed air—directly to aircraft, in addition to designing, building, and managing the associated power supply systems. The company also undertakes comprehensive maintenance for critical airport hardware, including passenger boarding bridges, baggage handling systems, security and inspection devices, and smart lane solutions. Furthermore, it services a wide range of building systems, covering HVAC, electrical, plumbing, fire suppression, kitchen installations, and lifting machinery. Beyond infrastructure, AGP extends its expertise to provide extensive support services for business aviation. This encompasses hangar facilities, aircraft cleaning, towing, water and waste management, marshalling, crew logistics and pass facilitation, bonded warehousing, and supplying various maintenance tools. Additionally, AGP is involved in the sale and servicing of aircraft ground support equipment, and innovates by developing, manufacturing, and distributing specialized food carts, such as HACCP-compliant reheating units. Established in 1965 as Japan Airport Ground Power Co., Ltd., the company adopted its current name, AGP Corporation, in September 2000. It is headquartered in Tokyo, Japan.
