Japan's healthcare system is facing mounting financial pressures as new data reveals widespread deficits among hospitals and care facilities, prompting the government to propose significant reforms to insurance payment structures that will affect all residents, including foreign nationals. According to NHK, the Ministry of Health, Labour and Welfare (MHLW) released data on November 26, 2025, showing that general hospitals in Japan recorded an average deficit of approximately 140 million yen (roughly $930,000 USD) during fiscal year 2024, even after including subsidies and other supplementary funding. This stark financial reality underscores the severe strain on Japan's medical infrastructure and sets the stage for upcoming changes to the national healthcare reimbursement system. The financial difficulties extend beyond hospitals. MHLW survey data indicates that over 37% of the approximately 8,000 facilities providing long-term care insurance services operated at a loss during the previous fiscal year. This widespread deficit situation affects various types of care facilities, from nursing homes to home-visit care providers, raising concerns about the sustainability of services that many elderly residents and their families depend upon. These financial pressures are driving the government to reconsider how healthcare and long-term care insurance premiums and out-of-pocket costs are calculated. Currently, Japan's national health insurance premiums are primarily based on employment income and household composition. However, the MHLW is now proposing a system that would incorporate financial income—such as investment returns, dividends, and capital gains—into the calculation of insurance premiums and copayment amounts. For expats living in Japan, this proposed change could have significant implications. Many foreign residents, particularly those working in finance, business, or who maintain investment portfolios in their home countries, may see their healthcare costs increase if they have substantial financial income beyond their salary. The current system largely overlooks such income sources when determining insurance obligations. According to NHK, the MHLW informed ruling party working group members on November 26 that implementation of this new financial income assessment system would take at least four years to establish. This timeline suggests that any changes would not take effect until 2029 at the earliest, giving residents time to prepare for potential increases in their healthcare-related expenses. The proposed reforms reflect a broader challenge facing Japan's social insurance system: how to maintain quality universal healthcare coverage in a rapidly aging society with increasing medical costs. Japan's population aged 65 and over now exceeds 29% of the total population, placing unprecedented demands on both medical facilities and long-term care services. The hospital deficit figures are particularly concerning because they represent the financial health of general hospitals—the backbone of Japan's medical system—after government support has already been factored in. Without subsidies, the deficit situation would be considerably worse. These losses make it difficult for hospitals to invest in new equipment, attract medical staff, or maintain facilities, potentially affecting the quality of care available to all residents. For foreign residents, understanding these developments is crucial for long-term financial planning. While the current healthcare system remains one of the world's most affordable and comprehensive, future changes may require budgeting for higher insurance premiums, particularly for those with diverse income sources. Expats should monitor official announcements from the MHLW and consider consulting with tax advisors familiar with both Japanese healthcare regulations and international income reporting. The government faces the delicate task of ensuring financial sustainability while maintaining the accessible, high-quality healthcare that residents—both Japanese and foreign—have come to expect. As these reforms develop over the coming years, staying informed about policy changes will be essential for all residents planning their financial futures in Japan.
