Directions: Read the following passage and answer the given questions. Japan is at the forefront of a demographic shift that is reshaping societies worldwide. With one of the most rapidly ageing populations globally, it faces unique challenges and opportunities in maintaining economic vitality and social stability. The Japanese government has developed a multifaceted approach to address these issues, encompassing healthcare, labor market reforms, and community-based initiatives. As of recent estimates, over 29% of Japan's population is aged 65 or older, making it the world's oldest society. The country's low fertility rate and high life expectancy contribute to this demographic phenomenon. While increased longevity is a testament to advancements in healthcare and living standards, the shrinking working-age population poses economic challenges. Dependency ratios are rising, with fewer workers supporting a growing number of retirees. Healthcare is a cornerstone of Japan's ageing population strategy. The country operates a universal healthcare system that provides affordable and high-quality medical services. However, the growing number of elderly individuals has strained resources. To address this, the government has introduced policies to shift focus from hospital-based care to community-based care. This model emphasizes home healthcare services, enabling older individuals to receive medical attention and support in familiar surroundings. Technological innovation plays a significant role in improving elderly care. Japan has been a pioneer in developing and deploying robotic assistants for caregiving. Robots equipped with artificial intelligence (AI) help with tasks such as lifting patients, providing companionship, and monitoring health conditions. These advancements not only alleviate caregiver burdens but also ensure the elderly can maintain a degree of independence. The ageing population has also prompted Japan to rethink its labor policies. To mitigate the economic impact of a shrinking workforce, the government is encouraging older individuals to remain employed longer. In 2021, Japan raised the mandatory retirement age for public servants to 65, with further plans to allow workers to continue until 70. Many private companies have followed suit, creating flexible work arrangements to accommodate senior employees. Additionally, the government is actively promoting women's participation in the workforce, addressing a long-standing gender gap. By enhancing access to childcare and promoting equal pay initiatives, Japan aims to unlock the potential of its underutilized human resources. Efforts are also underway to attract foreign workers, albeit at a cautious pace, given Japan's historically conservative approach to immigration. Policies such as the Specified Skilled Worker visa program aim to fill labor shortages in key sectors like healthcare and construction. Japan's pension system faces sustainability challenges due to the increasing ratio of retirees to active contributors. To ensure its viability, the government has implemented several reforms, including raising the pension eligibility age and encouraging private retirement savings. Additionally, public awareness campaigns emphasize the importance of financial planning for old age. Recognizing the importance of social inclusion, Japan has also invested in community-building initiatives to combat the isolation often experienced by the elderly. Programs such as "Silver Human Resource Centers" offer older individuals opportunities to engage in part-time work or volunteer activities, fostering a sense of purpose and community. Intergenerational programs that bring together youth and seniors are also gaining popularity, promoting mutual understanding and support. Japan has embraced smart city concepts to cater to an ageing society. Urban planning now incorporates features like barrier-free public spaces, accessible transportation systems, and community hubs for elderly residents. Technology-driven solutions such as health monitoring apps and remote consultations have become widespread, ensuring older individuals can easily access healthcare and support services. Despite these efforts, challenges remain. The cost of maintaining an ageing society is immense, and Japan's public debt is among the highest globally. Balancing the needs of the elderly with those of younger generations requires careful policy-making and equitable resource allocation. Furthermore, cultural attitudes towards immigration and gender roles must evolve to fully address labor shortages. Japan's proactive approach to its ageing population provides valuable lessons for other nations facing similar demographic trends. By investing in healthcare, technology, and inclusive policies, Japan demonstrates how an ageing society can adapt and thrive. While challenges persist, the resilience and innovation embedded in Japan's administrative strategies offer hope for a balanced and sustainable future. This comprehensive approach positions Japan not only to manage its demographic challenges but also to serve as a global leader in addressing the complexities of an ageing world. What is a plausible reason for Japan promoting the participation of older individuals in the workforce?
