Welfare ministry officials said the percentage of elderly people certified as "requiring long-term care" fell due to efforts to prevent long-term frailty and that the estimated number of required caregivers declined as a result. Even so, Japan is not out of the woods as it faces severe labor shortages. According to estimates by the National Institute of Population and Social Security Research and other sources, the productive-age population, or those between 15 and 64, will decline from 73.95 million in 2023 to 62.13 million in 2040. The number of elderly people aged 65 or older is estimated to increase from 36.23 million to 39.28 million over the same period.
