This case uniquely challenges students by introducing the history of how LIXIL transformed its corporate social responsibility (CSR) program to create shared value within the global sanitation sector by launching the SATO business unit as a social enterprise. SATO is a “self-sustaining social business that establishes a local Make, Sell, Use cycle in the community – creating jobs and allowing local manufacturers and stakeholders to continue the business independently” (LIXIL, 2019). From 2012 to 2021, NGOs helped the company design and market the SATO toilet pan and other products that form the SATO business unit. The SATO business unit must balance its social mission of improved sanitation with the need to gain a profit and become a sustainable business – the ongoing challenge of social entrepreneurship.
