Seeing a headline like “Japanese households hold over ¥20 million in average savings” and thinking “my own savings are nowhere close to that” is a common reaction — and there’s a real statistical reason for the gap. Averages get pulled hard by a small number of extreme values, which means the average often looks nothing like most people’s actual experience. This guide uses first-party data from Japan’s National Tax Agency, the Statistics Bureau, and the Ministry of Health, Labour and Welfare (MHLW) to look past the headline averages toward the median figures — and life-expectancy data — that matter more for realistic retirement planning.
This is general statistical information, not individual investment or retirement planning advice. All figures shift year to year and by survey methodology. Consult a financial planner using the latest data and your own circumstances before making decisions.
Unpacking the “¥4.78 million average income” figure
According to Japan’s National Tax Agency’s Private Sector Salary Survey (fiscal 2024 data), the average annual salary for someone employed the full year was ¥4,780,000 (up 3.9% year over year). Broken down by gender, men averaged ¥5,870,000 and women averaged ¥3,330,000 (NTA, Fiscal 2024 Private Sector Salary Survey).
Plenty of people looking at that ¥4.78 million figure will conclude their own income is “below average.” That reaction is statistically well-founded. Salary distributions tend to have a long right tail — a relatively small number of high earners pull the mean upward — which means the income of someone genuinely in the middle of the distribution (the median) tends to sit below the average.
In other words, earning less than the average income doesn’t by itself mean your standard of living is below typical. For a large share of the population, an income below the reported average is actually closer to the norm than the average figure suggests.
The ¥20.59 million average savings figure, and its median
The same pattern shows up in savings data. According to the Statistics Bureau’s Family Income and Expenditure Survey (2025, households of two or more people), average household savings were ¥20,590,000 — the seventh consecutive year of increase. Taking that number at face value and concluding “the typical Japanese household has saved ¥20 million” would be a mistake.
The same survey also reports that the median among households that hold savings was ¥12,640,000, and the median including households with zero savings was ¥11,670,000 (Statistics Bureau, Family Income and Expenditure Survey — Savings and Liabilities).
That’s a gap of more than ¥8,000,000 between the average and the median. The gap reflects a relatively small number of households holding very large financial assets — tens of millions of yen or more — pulling the average sharply upward.
| Metric | Amount (2025, households of 2+) |
|---|---|
| Average savings | ¥20,590,000 |
| Median (households with savings) | ¥12,640,000 |
| Median (including zero-savings households) | ¥11,670,000 |
For most people, the median is the more relatable number. Anchoring a retirement savings target purely on the “¥20 million average” risks setting a goal that’s disconnected from — and considerably larger than — where the typical Japanese household actually sits.
How long should retirement savings actually last? Life expectancy versus median lifespan
Beyond how much to save, a second critical number for retirement planning is how many years of expenses to plan for. Here too, it’s worth looking past the single “average life expectancy” figure to a second, complementary metric.
According to MHLW’s fiscal 2024 abridged life tables, Japan’s average life expectancy (remaining life expectancy at birth) is 81.09 years for men and 87.13 years for women. The same life tables also publish a median lifespan — the age by which half of a birth cohort has died — which comes in at 83.89 years for men and 90.04 years for women, 2-3 years longer than the average life expectancy at birth (MHLW, Overview of the Fiscal 2024 Abridged Life Tables).
Separately, remaining life expectancy at age 65 — how many more years, on average, someone who has already reached 65 can expect to live — is 19.47 years for men and 24.38 years for women. In practical terms: someone retiring at 65 should, on average, plan for roughly another 20 to 24 years of living expenses.
| Metric | Men | Women |
|---|---|---|
| Life expectancy at birth | 81.09 years | 87.13 years |
| Median lifespan | 83.89 years | 90.04 years |
| Remaining life expectancy at 65 | 19.47 years | 24.38 years |
Anchoring a retirement plan purely on average life expectancy at birth risks overlooking the fact that close to half of any birth cohort lives longer than that figure. Factoring in median lifespan and remaining life expectancy at 65, and planning for a somewhat longer horizon than “average life expectancy” alone, is one practical way to reduce the risk of retirement savings running out too early.
Three things to keep in mind when reading “average” figures
A few practical takeaways from these statistics for retirement and household planning:
- Check the median alongside the average. Distributions of income and savings tend to be pulled upward by a small number of extreme values. Where available, check the median too, to get a figure closer to your own likely experience.
- Look for breakdowns by age bracket and household type. Beyond the all-household average and median, data broken down by age bracket and household composition — which the Statistics Bureau also publishes — tends to be more directly useful for your own planning.
- Plan for a horizon somewhat longer than “average life expectancy.” Given median lifespan and remaining life expectancy data, it’s worth modeling retirement funding for a period with some margin built in, rather than assuming funds only need to last exactly to average life expectancy.

FAQ
What is the average annual income in Japan?
According to Japan's National Tax Agency Private Sector Salary Survey (fiscal 2024 data), the average annual salary for someone employed the full year was ¥4,780,000 — ¥5,870,000 for men and ¥3,330,000 for women. This is a mean, though, and salary distributions are typically pulled upward by a relatively small number of high earners, so the income of a 'typical' person sitting at the middle of the distribution tends to be lower than this average.
How different is average savings from median savings in Japan?
According to the Statistics Bureau's Family Income and Expenditure Survey (2025, households of two or more people), average household savings were ¥20,590,000. But the median among households that hold savings was ¥12,640,000, and the median including households with zero savings was ¥11,670,000. That's an ¥8M+ gap between the average and the median, driven by a relatively small number of households with very large financial assets.
Should retirement planning use the average or the median figure?
For most people, the median gives a more relatable picture. Averages are heavily influenced by a small number of extreme values (very high earners or very large asset holders) and don't represent the typical household well. When planning retirement savings, it's worth looking at both the average and the median — and ideally, data broken down by your own age bracket and household type — rather than anchoring on the average alone.
How many years of retirement expenses should I plan for?
According to Japan's Ministry of Health, Labour and Welfare's fiscal 2024 abridged life tables, remaining life expectancy at age 65 is 19.47 years for men and 24.38 years for women. The 'median lifespan' — the age by which half of a birth cohort has died — is 83.89 years for men and 90.04 years for women, 2-3 years longer than the average life expectancy at birth. These figures suggest planning for a somewhat longer horizon than 'average life expectancy' alone would imply.
