The number of people aged 100 or older in Japan has exceeded 100,000 for the first time, according to the Ministry of Health. As of the latest count, 107,677 individuals in the country meet the criteria, marking the highest total recorded since the nation began tracking such data in 1963. Of this group, 88% are women, and the oldest living woman is 114-year-old Kishimoto Fuyo of Kyoto, while the oldest man is 112-year-old Kato Hikaru of Kumamoto.

Health Minister Kenichiro Ueno expressed satisfaction that many Japanese citizens are living long, healthy lives, attributing progress to advances in medicine and technology. He also cautioned that sustaining the nation's social security system presents a growing challenge. Experts link the longevity trend to lifestyle factors, including a diet rich in fish, vegetables, and rice, as well as regular physical activity such as walking, cycling, and using public transportation.

Innovations tailored to older adults have emerged, including powered exoskeletons designed to assist mobility and adaptive eyewear that adjusts focus automatically. Japanese cuisine, characterized by low saturated fat and high vegetable intake, is frequently cited as a contributing factor to overall health.

Demographic pressures accompany the record number of centenarians. Japan's fertility rate fell to 1.14 in the most recent year, below the replacement level of 2.1 children per woman. Projections indicate the national population could decline to 87 million by 2070, down from a peak of 128 million in 2008. Currently, individuals aged 65 and older represent approximately 30% of the population, a share expected to approach 40% within the next five decades.

Prime Minister Sanae Takichi has described the demographic shift as a "quiet emergency," calling it an "existential crisis" for the country. In 2025, population decline was observed across all 47 prefectures except two, with the rate of reduction accelerating. Government initiatives aimed at boosting birth rates, including financial incentives and childcare support, have not yet reversed the downward trend.

Immigration has increased modestly in recent years, but foreign residents remain a small fraction of the total population at around 3%, and public resistance to expanding immigration levels persists. The Ministry released the data ahead of the annual "Respect for the Aged" holiday, during which the government traditionally honors newly turned centenarians with official letters and ceremonial sake.

Historical comparisons show the scale of change: when the first official survey was conducted in 1963, only 153 people were recorded as centenarians. The milestone of 1,000 was reached in 1981, and 10,000 by 1998. Earlier global comparisons of centenarian counts have raised questions about data accuracy, with some researchers suggesting inconsistencies in record-keeping or potential underreporting of deaths linked to pension claims. The Ministry noted that past miscounts may have resulted from incomplete documentation and localized practices affecting data reliability.

The current figure reflects improved tracking and verification processes, though officials acknowledge the complexity of maintaining precise records across a vast and aging society.
