Savings in Japan are a quiet source of anxiety for a lot of foreign residents. Prices keep climbing, your Japanese colleagues never discuss money, and you are left guessing whether your own balance is normal. If you grew up somewhere investing is simply what people do, the guessing gets harder still.
In this article, Masamichi Takayanagi, a certified financial planner, walks through what the data actually shows and where foreign residents tend to misread it.
The short version: the average is the wrong number to look at. Check the median, find your age bracket and household type, and count your investments as part of the picture. Do that and your position stops being a mystery.
Below, I cover average and median savings in Japan, the breakdowns by age and household, why Japanese and Western money habits diverge so sharply, and how to set a target that fits your actual life rather than a national statistic.

Chapter 1: How much are households saving in Japan?
Two cuts of the data do most of the work:
- Savings by age
- Savings by household type
Find the row closest to your own situation and the numbers stop being abstract.
Savings by age
According to the Japan Financial Literacy and Education Corporation (J-FLEC) Public Opinion Survey on Household Financial Behaviour 2025, average and median savings in Japan by age break down as follows:
*Includes households holding no financial assets at all.
| Age | Average | Median |
|---|---|---|
|
20s |
¥5.25M |
¥1.25M |
|
30s |
¥10.96M |
¥3.11M |
|
40s |
¥14.86M |
¥5.00M |
|
50s |
¥19.08M |
¥7.00M |
|
60s |
¥26.83M |
¥14.00M |
|
70s |
¥24.16M |
¥11.78M |
Savings in Japan move a great deal across the decades, peaking in a household’s 60s. The median starts at roughly ¥1.25M in the 20s, then builds steadily: ¥3.11M in the 30s, ¥5M in the 40s, ¥7M in the 50s.
The 60s are where it jumps, to around ¥14M. Three things land at once. Retirement lump sums arrive, mortgages are paid off, and education costs vanish.
So if you landed in Japan in your 30s, you are at the start of building wealth, not behind on it. Forget the households two decades ahead of you and use the median for your own bracket. That is a target you can actually hit.

Savings by household type
The same survey splits the figures by household composition:
| Household | Average | Median |
|---|---|---|
|
Single-person |
¥9.19M |
¥1.30M |
|
Two or more people |
¥19.40M |
¥7.20M |
The gap is wide. Households of two or more reported an average of ¥19.4M against a median of ¥7.2M. Single-person households came in at ¥9.19M and ¥1.3M.
Households with no financial assets at all skew single too: roughly 16% of multi-person households, against 30% of single-person households.
One nuance worth holding onto. Larger households earn more, but housing and education costs pile up alongside the income, which tends to hold their savings rate down rather than push it up.
Compare yourself against the households that resemble yours, and the distance to the headline average stops looking like a verdict. These figures are reference points.
Chapter 2: Why savings in Japan look different from home
If you read Japanese savings figures with the instincts you brought from home, you can easily misjudge where you stand.
The reason lies in what Japanese households do with their money. According to the Asset Formation White Paper 2025, around half of all household financial assets in Japan sit in cash and deposits, while equities and investment trusts account for only about 20%. In the United States, roughly 50% of household assets are held in stocks and funds, and only about 10% in cash. Europe falls between the two, with each category near 30%. In both cases, a clearly larger share of household wealth is invested.
Japan’s persistent preference for deposits has long-standing roots: years of low interest rates, the memory of falling prices, and a psychological hesitance toward investing.
Which brings us to the problem. If you hold significant investments, as many people from Western countries do, comparing yourself against Japan’s cash-based figures will make you look poorer than you actually are. What matters is your total assets, investments included.
The opposite risk is just as real. Leaving everything in cash and deposits in Japan means that inflation and the weak yen gradually erode the real value of your money.
The picture is changing, though. With the new NISA gaining ground, money continues to flow into equities and investment trusts, and the share of household assets held in securities is steadily rising.
And if there is a chance you will return home, one more variable belongs in your planning. Leaving Japan without meeting the ten-year pension qualification period entitles you to a lump-sum withdrawal payment, which returns part of the pension contributions you made. Knowing this in advance is one less thing to worry about.
Chapter 3: How much should you save in Japan, and where should you keep it?
Rather than matching the national average, it makes more sense to work backwards from a purpose and decide how much you need to save.
The first thing to build is an emergency fund. Three to six months of living expenses, held in a deposit account you can withdraw from at any time, gives you a foundation to work from.
As for a savings rate, 10% to 20% of your take-home pay is a reasonable guide. If you send money home each month, starting at a level you can manage is what keeps it going.
What matters is not only how much you save in Japan, but how you hold it. The balance between cash and investments is something to design around your own risk tolerance.
Chapter 4: Practical ways to grow your savings in Japan
The shortcut to saving more is to review your fixed costs before your variable ones.
Mobile bills come first, because the effect is the largest. Switching from a major carrier to a budget SIM cuts several thousand yen a month, and the saving continues indefinitely.
Next, cancel the subscriptions you no longer use and review insurance coverage that has become more than you need. Both bring your spending down without asking you to go without.
Foreign residents can also use furusato nozei, provided you pay resident tax. For an effective cost of ¥2,000, you receive return gifts, and most of your donation is deducted from your resident and income tax. Choose rice or meat, and it helps with your everyday grocery costs.
When it comes to where that freed-up money goes, NISA and iDeCo are the two mainstays.
NISA makes investment gains and dividends tax-free, and the freedom to withdraw at any time is part of its appeal. With an annual limit of ¥3.6 million and a lifetime limit of ¥18 million, it remains workable even if you plan to return home.
iDeCo offers three tax advantages at once: contributions are fully deductible from your taxable income, gains are tax-free, and further deductions apply when you receive the money. Contributing ¥20,000 a month can reduce your annual tax burden by tens of thousands of yen.
Bear in mind, though, that iDeCo funds generally cannot be withdrawn before the age of 60. If there is a real chance you will return home before long, building around the liquidity of NISA is the safer approach.
Putting your savings on autopilot lets your balance grow steadily, without relying on willpower.
Turn the room you create in your fixed costs into an emergency fund or NISA contributions, and build it into security for the future.
Chapter8: Summary
Household savings in Japan vary by age and family structure, and the average alone makes it hard to see the real picture. Compare the figures by age bracket and household type, note how savings peak in the 60s and how low the median runs for single-person households, and your own position starts to come into view.
Because around half of Japanese household assets are held in cash and deposits, the starting point differs from Western countries, where stocks and investment trusts take the lead. That makes it essential to look again at your total assets, investments included. Begin by securing an emergency fund, design a savings rate and an investment balance that match your purpose, and create room through reviewing your fixed costs and using furusato nozei. Do that, and you build a financial foundation that holds steady even after you return home.
