In a nation grappling with an ageing population, innovative robots like Pepper, AIBO, and PARO are being deployed to alleviate loneliness and cognitive decline among the elderly. These technological companions are transforming care in Japanese nursing homes
Japan, renowned for its technological advancements and high life expectancy, is confronting the challenges of a rapidly ageing population. To address issues such as loneliness, cognitive decline, and reduced mobility among the elderly, the nation is turning to innovative solutions in robotics.
At the forefront of this movement are social robots like Pepper, AIBO, and PARO, which have been integrated into numerous nursing homes and hospitals across Japan. These robots are designed to entertain, initiate conversations, and foster emotional connections with residents, thereby enhancing their mental and emotional well-being.
Standing at four feet tall, Pepper is one of Japan’s most advanced humanoid robots. It navigates on a base resembling a large white chess piece and is programmed to play songs from decades past, engaging residents in nostalgic musical sessions. Despite its lack of facial expressions, Pepper’s agile arm movements and fluid articulations captivate audiences, encouraging them to participate in activities such as calisthenics, which are reminiscent of routines broadcast on public television.
AIBO, developed by Sony, is a robotic dog that offers companionship to the elderly. Its design focuses on entertainment and emotional support, providing users with a sense of joy and comfort. Unlike traditional pets, AIBO does not require feeding or cleaning, making it an ideal companion for those who may not have the capacity to care for a live animal.
PARO is a therapeutic robot modelled after a baby harp seal, featuring soft textures and lifelike movements. When held, it emits gentle sounds and gazes with large, expressive eyes, eliciting feelings of tenderness and relief among users. PARO has been particularly effective in engaging individuals with dementia, Alzheimer’s, and other cognitive disorders, providing them with a sense of comfort and companionship.
Japan’s demographic landscape is shifting, with projections indicating a decline from the current population of 126 million to 87 million by 2070. By that time, it is estimated that 40% of the population will be over the age of 65. This trend has significant implications for productivity, housing, the pension system, and family dynamics.
For decades, the country has been searching for technological solutions to address the economic and social repercussions that stem from its rapidly ageing population
The decreasing birth rate has led to a child population of just 14.01 million, while the number of pets has surpassed that of children, reaching 15.9 million. This shift is evident in consumer trends, with supermarkets selling more adult diapers than those for babies and an increase in products catering to single-person households.
In response to these challenges, Japanese institutions are increasingly incorporating technology into elder care. The Shintomi Nursing Home in Tokyo, for example, utilises a combination of social robots and digital systems to monitor residents’ well-being. Devices analyse sleep patterns and detect when a diaper change is necessary, ensuring timely and efficient care.
Kimiya Ishikawa, the director of Shintomi and a specialist in elderly care, envisions a future where humans and machines collaborate seamlessly in caregiving. He notes, “No human being can take care of an elderly person 24 hours a day. Only a machine can do it.”
For many elderly individuals, robots have become integral companions. Seventy-five-yearold retiree Mieko Shimada has lived with her LOVOT robot for four years. Programmed to react to caresses, LOVOT provides her with a sense of family and companionship. Shimada shares, “When you express admiration for someone all the time, it can come across as disingenuous. With LOVOT, I don’t feel self-conscious.”
As the global population continues to age, the demand for technological solutions in elder care is expected to grow. Japan remains at the forefront of this movement, leveraging its expertise in robotics to enhance the quality of life for its elderly citizens. By integrating robots into caregiving, Japan is not only addressing the practical challenges of an ageing society but also redefining the nature of companionship and care in the modern world.
In conclusion, Japan’s innovative use of social robots represents a promising approach to mitigating the challenges associated with an ageing population. Through the deployment of companions like Pepper, AIBO, and PARO, the nation is pioneering a new model of elder care that blends technology with empathy, offering valuable lessons for societies worldwide.
