The supermarket market is undergoing significant transformation, particularly in Japan, where the adoption of artificial intelligence (AI) technologies is redefining traditional retail paradigms. Technological innovations, such as AI-driven employee smile monitoring and the use of smart cameras for security, raise ethical and practical questions. Simultaneously, the introduction of connected carts promises to transform the shopping experience. However, these technological advancements are not without risks, particularly concerning employee surveillance and potential price increases for consumers.
