A Closer Look at Japan’s Aging Population
In Japan, the number of centenarians continues to rise impressively. As of September 1st, the count reached 99,763, marking an increase of 4,644 from the previous year, according to the Ministry of Health. Notably, women represent 88% of these centenarians.

Among these, Shigeko Kagawa stands out as the oldest living person in Japan at 114 years old. Residing in the Nara region near Kyoto, Kagawa’s longevity is attributed to her active lifestyle. She worked as a midwife and general practitioner well into her 80s. “The extensive walking during house visits strengthened my legs, which are the source of my vitality today,” she was quoted as saying. Kagawa also enjoys watching television, reading newspapers, and practicing calligraphy, maintaining good eye health even at her advanced age.
The world’s oldest living person is currently Ethel Caterham from Britain, who celebrated her 116th birthday in August.
Japan’s Demographic Challenges
While the rising number of centenarians in Japan is noteworthy, the overall population trend paints a different picture. The country is experiencing a significant demographic shift, with its population decreasing at an unprecedented rate. In 2024, the population is expected to shrink by 900,000 people, the highest record to date.
This decline poses a “silent crisis,” as stated by the outgoing Prime Minister Shigeru Ishiba. In response, he has pledged to implement family-friendly policies such as more flexible work hours and free childcare services to encourage a reversal of this trend.
The aging population is also straining Japan’s social systems. With a higher proportion of elderly residents, healthcare costs are surging. At the same time, the workforce that contributes to social security systems is dwindling, intensifying the economic pressures on the country.
Scrutiny Over Longevity Data
However, the figures concerning Japan’s elderly, particularly the centenarians, should be approached with caution. In discussions about so-called Blue Zones—regions known for their high numbers of long-living inhabitants—some studies suggest that Japanese data might not be entirely reliable.
Research indicates that in places like Okinawa, celebrated for its many centenarians, accurate age records may not be verifiable due to the loss of documents during World War II. Furthermore, instances of pension fraud might also contribute to discrepancies in longevity data, casting doubts on some of the reported ages of the elderly.
Despite these concerns about data accuracy, the societal and economic implications of Japan’s aging population remain pressing issues that require effective and immediate addressing.
