Seniors with cognitive decline hold 260 trillion yen but struggle to manage finances, risking fraud and isolation

About 30 percent of seniors living independently in their communities with public nursing care support cannot manage basic financial tasks on their own, according to a Keio University survey conducted with the city of Izumi, Osaka Prefecture, between February and April 2025. Among those certified at Support Level 1, Support Level 2, or Care Level 1 under Japan’s long-term care system, 29.2 percent cannot make bank deposits or withdrawals independently, and 30.5 percent struggle to pay rent or utility bills. For those at Care Level 1, the figure rises to about 61 percent unable to handle both tasks. These individuals are expected to live at home, as special nursing homes typically require Care Level 3 or higher.

11.3 percent of respondents have fallen or nearly fallen victim to fraud schemes, and 22.0 percent of them did not consult anyone about the incidents. In a separate 2024 study led by Kyoto Prefectural University of Medicine, about 80 percent of consumer harm cases involving dementia or mild cognitive impairment went unrecognized by the victims themselves. Signs of cognitive decline—such as difficulty using ATMs or losing bankbooks and personal seals—are often observed by financial institutions, but reporting is rare. Banks risk legal criticism for disclosing customer information suggesting cognitive impairment without consent.

A 2021 revision to Japan’s Social Welfare Law introduced a 'multilayered support' framework, allowing legal information sharing among designated institutions under specific conditions. The city of Yaizu, Shizuoka Prefecture, has integrated financial institutions into its support network, enabling early intervention. The program covers about 20 households annually, with several dementia-related cases identified each year through bank-reported signs.

Professor Kohei Komamura of Keio University estimates that elderly individuals with cognitive impairment hold approximately 260 trillion yen in assets. They face mounting challenges in spending, protecting, and passing on their wealth. “We need to move quickly to put responses in place,” Komamura said. He advocates for new frameworks that balance protection, effective asset use, and respect for personal autonomy through stronger collaboration between financial and welfare systems.
