In 1993, the Japan Professional Football League (commonly known as the "J.League") was formed replacing the semi-professional Japan Soccer League as the new top-level club competition in Japan. It consisted of some of the top clubs from the old JSL, fully professionalized, renamed to fit communities and with the corporate identity reduced to a minimum. The new higher-standard league attracted many more spectators and helped the sport to hugely increase in popularity. The professionalized league also offered, and offers, incentives for amateur non-company clubs to become part of their ranks with no major backing from a company; major examples of community, non-company-affiliated clubs who rose through the prefectural and regional ranks into the major leagues are Albirex Niigata and Oita Trinita.
