Financial inclusion and financial gerontology in Japan's aging society.

Japan, the world's most rapidly aging society, faces increasing financial strains related to personalized dementia care. The government has shifted its focus from prevention to coexistence with dementia, as outlined in the 2023 Basic Act on Dementia. Emphasis on financial inclusion aligns with the G20's 2019 "Fukuoka Policy Priorities on Aging and Financial Inclusion", which addresses financial exclusion due to cognitive decline and poor financial literacy. While economic activity among older adults is already hampered by legal challenges and risks associated with dementia, outcomes are expected to worsen as the assets of older adults with dementia are projected to reach 215 trillion JPY ($1.4 trillion USD) by 2030. Government measures and research in financial gerontology advocate for protecting older adults and promoting flexible financial practices. Enhanced efforts and shared research outcomes are crucial for Japan to be a leader as an advanced aging society.
