About us


The Japan Auto Parts Industries Association (JAPIA) is an industry organization that was established in August 1969, when its predecessor, the Auto Parts Industries Association was reorganized as an incorporated association with a higher level of public interest. Today, the value of shipments of auto parts from member companies has reached approximately 20 trillion yen, supporting the manufacture of automobiles not only in Japan but also around the world.
Each and every one of these high-quality parts makes a significant contribution to the safety and comfort of automobiles. The environment surrounding the automotive parts industry is becoming more and more severe, and the industry is facing many challenges such as responding to structural changes, dealing with environmental issues, and promoting international cooperation.
JAPIA will continue to develop proactive business activities to contribute to the growth of the Japanese economy and society while promoting the sound progress of the "motorized society" through the automotive industry.

In 2018 (FY), the automotive related shipments was 60 trillion yen (19% of all manufacturing), of which 26trill. yen (8%) was for automobiles and 35trill. yen (11%) was for auto parts. In terms of employment, the automotive industry as a whole employed 900 thousand people in JAPAN, which accounts for 12% of the total employment in the manufacturing industry, of which 700,000 were in the auto parts industry, accounting for 9% of the total.
