Key Points:

Japan's population of centenarians has surpassed 100,000 for the first time, reaching 107,677, with 88% being women; the oldest individuals are a 114-year-old woman and a 112-year-old man.
Health Minister Kenichiro Ueno highlighted advances in medicine and technology as key factors for longevity but warned about challenges in sustaining the social security system amid an aging population.
Japan’s aging population is attributed to a healthy diet and active lifestyle, but the country faces a declining birth rate, with a record low fertility rate of 1.14 and an expected population drop to 87 million by 2070.
The elderly (65+) currently make up about 30% of Japan’s population and are projected to reach nearly 40% by 2070, prompting concerns from authorities who label this demographic shift an "existential crisis."
Despite government efforts to boost birth rates and increased immigration, Japan continues to see population decline due to complex social factors, including lower marriage rates, more women in the workforce, and high child-rearing costs.
