**Title: Japan Surpasses 100,000 Centenarians for the First Time**

Japan has reached a significant demographic milestone, with the number of individuals aged 100 years or older exceeding 100,000 for the first time. According to recent statistics released by the health ministry, the country is now home to 107,677 centenarians, the highest figure globally. This remarkable increase in longevity is attributed to various factors, including advancements in healthcare, nutrition, and lifestyle choices.

Health Minister Kenichiro Ueno expressed his delight at the growing number of citizens living long, healthy, and active lives. He noted that improvements in medicine and technology have played a crucial role in this trend. However, Ueno also highlighted the challenges posed by an aging population, particularly concerning the sustainability of Japan's social security system.

Among the centenarians, women represent a staggering 88%, with the oldest woman being 114-year-old Kishimoto Fuyo from Kyoto City. The oldest man, Kato Hikaru, is 112 years old and hails from Kumamoto. The increasing number of centenarians reflects Japan's long-standing reputation for longevity, which experts attribute to a combination of a healthy diet, active lifestyles, and social factors.

Japanese cuisine, which is rich in fish, vegetables, and rice, is believed to contribute significantly to the population's extended lifespan. This diet is generally lower in saturated fats compared to many Western diets. Additionally, older adults in Japan tend to maintain active lifestyles, often walking, cycling, or using public transportation, which further supports their health.

Despite the increasing number of centenarians, Japan faces a demographic crisis characterized by a declining birth rate. The total fertility rate in Japan fell to a record low of 1.14 last year, well below the replacement level of 2.1 children per woman. Projections indicate that the total population may decrease to approximately 87 million by 2070, a decline of about 30% from its peak of 128 million in 2008. Currently, around 30% of the population is aged 65 and older, a figure expected to rise to nearly 40% by 2070.

This demographic shift has led Japanese authorities to describe the situation as an "existential crisis." Prime Minister Sanae Takichi has referred to the declining birth rate as a "quiet emergency," emphasizing the urgency of addressing the issue. In 2025, Japan's population is projected to decline in all but two of its 47 prefectures, with the rate of decline accelerating.

Despite various government initiatives aimed at encouraging young people to have more children, such as subsidies and support programs, these efforts have not significantly impacted birth rates. Experts suggest that the reasons for the low fertility rate are multifaceted, including lower marriage rates, increased participation of women in the workforce, and the rising costs associated with raising children. Although immigration has seen a slight increase in recent years, foreigners still make up only about 3% of Japan's population, and there is growing opposition to accepting more immigrants.

The centenarian statistics were released in conjunction with Japan's annual "Respect for the Aged" public holiday, during which the government honors those turning 100 with personal letters and traditional sake cups. This celebration underscores the cultural significance placed on aging and the contributions of older generations to society.

Japan's centenarian survey began in 1963, when there were only 153 individuals aged 100 or older. This number rose to 1,000 by 1981 and reached 10,000 by 1998. However, past studies have raised questions about the accuracy of global centenarian figures, citing potential data errors and unreliable public records. A government audit in 2010 revealed over 230,000 individuals listed as centenarians who were unaccounted for, some of whom had passed away decades earlier. This miscounting was attributed to inconsistent record-keeping and suspicions that some families may have concealed the deaths of elderly relatives to continue receiving pensions.

As Japan navigates the complexities of an aging population and declining birth rates, the country continues to celebrate the remarkable achievement of its centenarians, while also confronting the pressing challenges that lie ahead.
