Japan centenarian population exceeds 100,000 for the first time

The number of centenarians in Japan has surpassed 100,000 for the first time, reaching 107,677 according to government statistics from the Health and Welfare Ministry. Approximately 88% of these individuals are women. While Health Minister Kenichiro Ueno attributed the increase to advancements in medical technology, healthy lifestyles, and diet, he also emphasized the necessity of maintaining a sustainable social security system as the population continues to age and decline.

This demographic shift presents significant social and economic challenges. Beyond the strain on care systems, there is a rising prevalence of dementia, affecting an estimated 4.5 million people in the country, with another 10 million experiencing mild cognitive impairment. Economists have noted the massive scale of assets held by those with cognitive impairments, with approximately 315 trillion yen in savings tied to individuals with dementia or its precursors.

Additionally, Japan faces a declining birth rate. Surveys indicate that over 20% of single adults aged 18 to 34 have no intention of marrying, citing high costs of child-rearing and education as primary concerns.
