    Speakers:

    Mr Robin Lewis, co-founder of mymizu

    In 2019, Mr Lewis co-founded mymizu, Japan's first water refill app, as an initiative to reduce consumption of single-use plastics. With nearly 200,000 water refill spots around the world, the app includes cafes and restaurants, public spaces like airports and train stations, as well as spring water sources in areas like Nagano and Hokkaido, Japan. To commemorate World Water Day, Mr Lewis and Prof. Oki, one of Japan's leading hydrologists, discussed what water means to them, current trends in global water issues, and promising initiatives to help overcome water-related challenges.
