Part 4/9:
Japan stands at the forefront of humanoid robotics, particularly in developing female robots. The country's cultural and societal context has catalyzed this technological evolution. With a significant proportion of its population aged 65 or older, Japan faces challenges in healthcare and elder care. As the demand for caregiving services outpaces the availability of human caregivers, robots are emerging as viable solutions.
Additionally, Japan's declining birth rate and rising social isolation—especially among the elderly and single adults—further contribute to the acceptance of robots as companions. Unlike many other societies where robots are viewed primarily as tools, Japan has embraced the notion of robots as social entities, easing loneliness and providing emotional support.
