The Japanese automobile industry is one of the largest in the world. It rapidly grew from the 1970s-1990s to become the world's largest producer, manufacturing up to 13 million cars per year. It is now the third largest producer. The Japan Automobile Manufacturers Association (JAMA) represents major Japanese automakers and supports the industry's development. The industry faces opportunities in global demand for environmentally friendly vehicles, but also threats such as natural disasters and a strengthening yen exchange rate.
