The Reality of Post-Retirement Medical Costs - Out-of-Pocket Expenses That Increase with Age
According to estimates by Japan's Ministry of Health, Labour and Welfare (fiscal 2023), lifetime medical costs for Japanese people average approximately 29.66 million yen for men and women combined (roughly 30 million yen), with about 47% concentrated after age 70. The out-of-pocket medical cost share for working-age adults is 30%, but this is reduced to 20% for ages 70-74 and 10% for ages 75 and over (30% for those with income comparable to working-age adults) as of August 2026. However, even with lower cost-sharing ratios, actual spending increases due to higher frequency of medical visits and rising total medical costs. In the same ministry estimates, total medical costs per person (fiscal 2023, health insurance programs) rise from approximately 495,000 yen at ages 65-69 to approximately 781,000 yen at ages 75-79 and approximately 1,087,000 yen at ages 85-89, and what you pay at the counter is that total multiplied by your cost-sharing ratio and then capped by the High-Cost Medical Care Benefit. Furthermore, costs not covered by insurance (private room charges, advanced medical treatments, dental implants, etc.) are entirely out-of-pocket, so actual medical-related spending exceeds these figures.
The Kogaku Ryoyo-hi Seido (High-Cost Medical Care Benefit system) is an important safety net that caps monthly out-of-pocket medical expenses. For those aged 70 and over in the standard income bracket (annual income up to about 3.7 million yen), the caps from August 2026 are 22,000 yen per month for outpatient care per person (216,000 yen annual cap) and 61,500 yen per month on a household basis including hospitalization (with an annual cap of 530,000 yen). Through July 2026, the caps were 18,000 yen per month for outpatient care (144,000 yen annually) and 57,600 yen per month per household. Cap amounts are scheduled to be revised in stages, so check your own income bracket and the amounts that apply when you receive care. Thanks to this system, even when receiving expensive treatments such as cancer care, out-of-pocket costs do not spiral without limit. However, meal charges, private room fees, and transportation costs are not covered by this system.
The Reality of Nursing Care Costs - Preparing for Over 5 Million Yen in Out-of-Pocket Expenses
According to the Japan Institute of Life Insurance's fiscal 2024 nationwide survey on life insurance, one-time nursing care expenses (home modifications, nursing care equipment purchases, etc.) averaged approximately 470,000 yen in total, ongoing costs averaged approximately 90,000 yen per month, and the average duration of care was approximately 55 months (4 years and 7 months). Combining these three figures gives a total of roughly 5.4 million yen. One-time expenses averaged approximately 740,000 yen in the fiscal 2021 survey, so this figure swings considerably from one survey to the next. However, this is merely an average; when long-term facility care is needed due to dementia, costs exceeding 10 million yen are not uncommon. The out-of-pocket share for nursing care insurance is 10% in principle (20-30% for those with income above certain thresholds), but amounts exceeding the nursing care insurance benefit limits are entirely out-of-pocket.
An often-overlooked aspect of nursing care costs is the economic burden on caregivers. According to the Employment Status Survey (2022) by Japan's Ministry of Internal Affairs and Communications, 106,000 people left their previous job for nursing or caregiving reasons within the preceding year, up from 99,000 in 2017 and reversing an earlier downward trend. This 'kaigo rishoku' (leaving work to provide care) delivers a double economic blow of reduced income for the caregiver and lower future pension benefits. By appropriately utilizing nursing care services and consulting early with the Chiiki Hokatsu Shien Center (Community Comprehensive Support Center), it is possible to reduce the family's burden while optimizing nursing care costs.
Retirement Financial Planning That Incorporates Medical and Nursing Care Costs
When incorporating medical and nursing care costs into retirement financial planning, it is effective to separate 'basic living expenses' from a 'medical and nursing care reserve fund.' Basic living expenses are covered by pension and asset withdrawals, while a separate reserve of 5-10 million yen is set aside for medical and nursing care. This reserve should be held in highly liquid forms such as savings deposits or individual government bonds, ensuring it can be accessed immediately when needed. Private medical and nursing care insurance is also an option, but it should be considered as a supplement to fill gaps after accurately understanding the coverage of public systems. Excessive insurance enrollment can burden premium payments that impede wealth building, so the basic approach should be to maximize the use of public systems.
There is no need to be overly fearful of medical and nursing care costs, but preparation based on realistic estimates is essential.
Next Actions to Prepare for Medical and Nursing Care Costs
To make your preparations for medical and nursing care costs concrete, start by checking the out-of-pocket cap amounts under the High-Cost Medical Care Benefit system of your current health insurance. Since cap amounts differ by income bracket, it is important to know which bracket you fall into. Next, review the coverage of any private medical or nursing care insurance you currently hold and check for overlap with public systems. If you are paying excessive premiums, it may be more rational to redirect those funds toward wealth building.
Set a goal of accumulating 5-10 million yen as a medical and nursing care reserve fund, separate from basic living expenses. This reserve should prioritize liquidity, held in forms such as ordinary savings deposits or individual government bonds that can be accessed immediately when needed. Use a compound interest calculator to estimate the required contribution amount from your current age to retirement, and incorporating it into a comprehensive wealth-building plan alongside iDeCo and NISA will help build the foundation for a secure retirement.
