Satoko Kishimoto was an environmental activist and active in the youth environmental movement in Japan in the 1990s. She began working with TNI in 2003, at the time of 3rd World Water Forum held in Kyoto, Japan. TNI successfully organized a seminar on Alternatives to Water Privatisation, which was the starting point of the Water Justice Project. In 2005, the Reclaiming Public Water (RPW) Network was created with the contributors to the book 'Reclaiming Public Water'. TNI serves as the coordinating hub of the RPW network and Satoko is the coordinator of the network. The RPW network connects activists, trade unionists, researchers, community activists, and public water operators from around the world, and advocates progressive public water reforms and Public-Public Partnerships as the key elements for solving the global crisis in access to clean water and sanitation.
