With the intensifying shortage of care-providers and mounting financial burden of an aging population in Japan, artificial intelligence (AI) offers a potential solution through AI-driven robots, chatbots, smartphone apps, and other AI medical services. Yet Japanese acceptance of medical AI, especially patient care, largely depends on the degree of ‘humanness’ that can be integrated into intelligent technologies. As empathy is considered a core value in the practice of healthcare workers, artificially intelligent agents must have the ability to perceive human emotions (...) and respond in an affective, human-like manner. This paper presents the results of a nationwide survey in Japan 2023 about the public perception of the use of emotionalized AI (EAI) in healthcare. The sample included 2000 Japanese citizens from 20 to 69 years old with an average age of 45 years. The questionnaire included 65 items in six categories: demographic, perception of the existing healthcare system, attitude towards the use of AI, and EAI in healthcare, trust and privacy concerns and fear of AI, and seeking literacy on new technologies. The analysis of the responses demonstrates that overall, the Japanese population has a limited knowledge of AI, EAI, and smart technologies but trusts the healthcare system, physicians, and staff to use it properly, with little worries over the potential pitfalls related to data security and safety. However, they prefer the use of more human resources and are concerned about privacy and the high cost of new technology, and believe little information is being provided to them through government and media.
