In Japan, a network of women known as Yakult Ladies deliver probiotic milk drinks to people's homes, providing a vital source of routine, connection, and care, especially for the elderly. This delivery network has become an informal social safety net, helping to combat loneliness in a country with a rapidly aging population. The Yakult Ladies are self-employed and offer a friendly face, weekly check-ins, and a lifeline of human connection to their customers. The program has been in place since 1963 and has become an integral part of Japanese culture.
