Popular frame manufacturers include Nagasawa, 3Rensho, Makino, Kalavinka, Level, Bridgestone, Panasonic, and Samson. Other components come from Japanese manufacturers like Shimano, Nitto, Hatta, MKS, Kashimax, and Sugino.[citation needed] Because the primary goal of the NJS is to support the Japanese manufacturing industry, its bureaucracy is typically resistant to the certification of foreign manufacturers' components. The few exceptions to this are Italian cycling equipment manufacturers Campagnolo and Cinelli, which received NJS certification for some components.[1]
