TOKYO – an employee at a Japanese company, identified onyl as A, expressed dismay at the increasing deductions from his salary for social insurance premiums, including health insurance. “After taxes, about 30% of my salary disappears,” he lamented.
Rising Costs Strain Workers
The rapid aging of Japan’s population is driving a surge in health insurance premium rates. This trend is raising concerns about the growing burden on the working-age population, which shoulders approximately 40% of the medical expenses for the elderly. Some are advocating for increased taxation on wealthier individuals to alleviate the pressure. Experts suggest that South Korea should take note of these warning signs.

Health Associations Feel the Pinch
According to a report by the nihon Keizai shimbun, the average premium rate for ”health associations,” which cover many Japanese employees, reached 9.34% this year. This marks an increase of 0.03 percentage points from the previous year, continuing an 18-year upward trend. Japan’s health insurance system comprises “Kunbi Associations” for large companies, “Association gunbi” for SMEs, and “National Gunbons” for the self-employed, managed by local governments. While specific rates vary by union and region, labor and management typically share the costs equally.
Financial Deterioration Cited
The escalating premium rates are attributed to a deteriorating financial situation within the health insurance system. The Nihon Keizai Shimbun’s analysis of health agreements projects a total deficit of 3.782 trillion yen this year, marking the third consecutive year of deficits. Approximately 76% of health associations, totaling 1,043 unions, are expected to operate at a loss. Consequently, 149 unions are planning to raise premium rates this year to avoid depleting their reserves.
Aging Population a Key Factor
A primary driver of the health insurance deficit is the rising medical expenses of the elderly. Japan has a separate health system for those aged 75 and older, wiht health associations and Association Gunbi covering about 40% of the costs.the burden is intensifying as Japan’s “Dankai generation” (born 1947-1949) enters this age bracket. subsidies for the elderly are projected to reach 2.5353 trillion yen this year, a 2.5% year-on-year increase.
Overall Burden on Households
last year, social insurance premiums in Japan accounted for 20% of household income, with taxes representing an additional 7%. Including indirect taxes like consumption tax, households allocate roughly 30% of their income to social insurance premiums and taxes. The Nihon keizai Shimbun noted that this trend “makes it challenging to increase spending by pressing the disposable income.” In December, Keidanren, Japan’s leading economic association, proposed strengthening taxation on wealthy individuals to the government as a means of curbing social insurance premium burdens on the general population.
