This document summarizes the history and current state of corporate social responsibility in Japan. It traces the roots of CSR back to 17th century merchant codes of conduct focused on serving societal needs as well as individual interests. Modern CSR efforts in Japan address environmental sustainability, such as Toyota's efforts to reduce emissions, as well as social issues like supporting education and disaster relief. However, the document also identifies opportunities for improving CSR, such as addressing overwork culture to improve worker welfare, increasing women's roles in business to promote gender equality, and reforming whaling practices to improve Japan's global reputation for sustainability.
