Cost of Raising a Child in Japan

How much does it cost to raise a child in Japan?

For a typical middle-income Japanese household on an all-public school track, raising one child from birth through age 17 costs roughly ¥16,387,500 in 2026 yen, before university. Spread across 18 years, that is about ¥910,417 a year, or ¥75,868 a month, for the entire time your child lives at home. The figure draws on Japan Cabinet Office child-rearing cost surveys and MEXT (Ministry of Education) survey of learning expenses, brought forward to current yen.

What makes Japan's number distinctive is not just the total but its shape and its range: education spending, driven heavily by juku (cram school) attendance across both public and private tracks, makes up a notably larger share of the total than in most countries, and the gap between an all-public and an all-private education is larger here than the state-to-state or province-to-province swings in this series' other calculators. The calculator above adjusts for income, family size, and school track, the three factors that move the total the most.

How the cost of raising a child in Japan calculator works

1. It starts from a Cabinet Office and MEXT-based national baseline. We begin with Japan Cabinet Office child-rearing cost survey data combined with MEXT's survey of learning expenses, for a middle-income, two-child family, brought forward to 2026 yen. That baseline is about ¥19,000,000 per child before adjustment.
2. It adjusts for your income. Spending on children rises with household income. Moving the income slider scales the estimate from ¥3,000,000 to ¥35,000,000-plus of household income.
3. It adjusts for school track. Choose all-public or all-private, kindergarten through high school. This is the dominant cost fork in Japanese education spending, sourced directly from MEXT, not a location guess, and it is deliberately just two options: real families often mix tracks (public elementary, private junior high, and so on), and these two settings bracket that range rather than describe any one typical path.
4. It adjusts for the number of children. Bigger families spend less per child thanks to shared bedrooms, hand-me-downs, and bulk shopping, so the per-child figure rises for one-child families and falls for three or more.

We do not offer a prefecture selector for Japan, since prefecture-level cost data on child-rearing is less consistently published than school-track data, which MEXT publishes nationally every survey cycle. You can add an optional estimate for university, currently about ¥6,500,000 for four years at a national university away from home, covering tuition of roughly ¥535,800 a year plus living costs, clearly separated from the birth-to-18 total and unaffected by your school-track choice.

A worked example: all-public versus all-private

Take the default: a household earning ¥6,500,000, two children, all-public schools. That comes to roughly ¥16,387,500 per child to age 18, about ¥910,417 a year.

Now switch the school track to all-private, keeping income and family size the same. The total rises to about ¥27,694,875, a difference of ¥11,307,375 — roughly 69 percent higher, driven entirely by the education category, which MEXT's own data puts at about 3.3 times higher for an all-private track (¥19.76 million versus ¥5.96 million over the 15 years from kindergarten through high school). Every other category, housing, food, transport, healthcare, stays exactly the same yen amount either way; only education changes, because that is genuinely the only thing school choice changes.

Add four years of university to the all-public scenario and the combined figure rises to about ¥22,887,500. University cost is modeled the same way regardless of school track, since MEXT's public/private comparison covers kindergarten through high school only.

Why juku (cram school) drives the education category

In most countries, "childcare and education" is a moderate slice of the total. In Japan it is the largest single category in our model, about 30 percent at the all-public default, because juku attendance is close to the norm rather than the exception, and this is true on both tracks, not just the private one. MEXT's own learning-expense data shows that for public elementary and junior high school, out-of-school activity costs, juku chief among them, make up more than 60 percent of total learning expenses, actually a larger share than for private junior high and high school, where formal school tuition itself dominates the bill instead. Juku spending intensifies sharply from junior high onward: regular weekly fees are compounded by intensive exam-prep courses ahead of high school entrance exams (koko juken), typically taken around age 15, and it is common for families to spend more on juku in the three junior-high years than on public school costs themselves in that same period. This is a real structural feature of Japanese education spending on both tracks, not an artifact of our model or something folded only into the private-school number.

Japan's newer childcare subsidies

Since October 2019, Japan has provided free early childhood education and care for children aged 3 to 5 at kindergartens, nursery schools, and certified childcare centers, up to a monthly cap (¥37,000 for kindergarten-track facilities). For children aged 0 to 2, the same free-of-charge treatment applies only to households exempt from residents' tax (broadly, lower-income households), up to a ¥42,000 monthly cap; households above that threshold continue to pay standard 0-2 fees. This is a genuine, dated policy change, not a static assumption: it means the 0-5 portion of this model's childcare cost is lower than it would have been on pre-2019 data, and it is why our baseline does not assume families pay full market-rate fees for the youngest ages.

Where the money actually goes

The result panel breaks the total into categories reflecting Japanese household expenditure patterns for families with children, on the all-public track by default; switching to all-private reshapes these bars substantially, since only the education category changes in yen terms while the total grows around it:

• Childcare and education, about 30 percent (all-public). The largest category even before switching tracks, driven substantially by juku and exam-prep costs from junior high onward. Roughly 3.3 times higher on the all-private track.
• Housing, about 26 percent (all-public). Notably lower than the US or UK equivalent share outside central Tokyo, though housing in central Tokyo runs much higher than the national picture this figure represents. Unchanged by school track.
• Food, about 17 percent (all-public). Rises steadily through the teenage years. Unchanged by school track.
• Transport, about 10 percent (all-public). Lower than in car-dependent countries, reflecting extensive public transport availability in most Japanese cities. Unchanged by school track.
• Miscellaneous, about 9 percent (all-public), and clothing, about 5 percent. Activities, school supplies, and everything else. Unchanged by school track.
• Healthcare, about 3 percent (all-public). Low thanks to Japan's universal health insurance system, which covers the large majority of medical costs. Unchanged by school track.

Where Japan's cost curve differs from the US

The shape is the real story here, and it is close to the inverse of the US shape. American child-rearing costs typically spike early, in paid childcare during the pre-school years, and spike again late, when college tuition lands as a lump sum. Japan's curve, since the October 2019 reform, is comparatively flat and low through ages 3 to 5 for most households, and even the 0-2 years are softened for lower-income households under the same reform. Instead, Japan's steepest climb starts at junior high (age 12 to 15) and continues through the university-entrance-exam year of high school, as juku intensity and fees ramp up ahead of koko juken and then daigaku juken. Where a US family's quietest, most predictable years are often the middle-school-age years, those are Japan's most expensive ones, before university is even a factor.

Japan's child allowance (jido teate)

Japan's child allowance, jido teate, was significantly expanded in a reform effective October 2024. As of that reform: children under 3 receive ¥15,000 a month regardless of birth order; a first or second child aged 3 through the end of junior high receives ¥10,000 a month; a third or later child receives ¥30,000 a month from birth all the way through the end of high school (the March 31 after they turn 18). The previous household income cap was removed entirely, and payments now arrive six times a year (every two months) instead of three. Over 18 years this can be worth well over ¥2,000,000 per child, more for a third or later child, a meaningful offset to the totals above. We show it as a note rather than subtracting it, since the exact amount depends on the child's age, birth order, and the number of children in the household.

Education savings: Japan had a dedicated vehicle, and no longer does

Unlike Germany, Japan actually had a tax-advantaged, child-specific investment account: Junior NISA, which let a minor hold tax-free investment gains toward their own future, including education costs. Junior NISA stopped accepting new investments as of the end of December 2023, discontinued as part of the broader NISA overhaul that took effect in January 2024. Existing Junior NISA holdings keep their tax-free treatment until the child turns 18, and since January 2024 the previous withdrawal restrictions have actually been lifted, meaning a family can withdraw the full balance tax-free at any time, though only by closing the account entirely rather than withdrawing part of it. No new Junior NISA accounts can be opened, and no further contributions can be made to existing ones. Families saving for a child's future now generally use a regular adult NISA account instead, which has no education-specific design and is not available to the child directly until they turn 18 (Japan's NISA accounts are age-gated to 18 and over). A successor "Kodomo NISA" (child NISA) has been reported as under government consideration for a possible 2027 start, but it is not confirmed policy and does not exist yet as of this page's last review date below.

Assumptions and methodology

• Default values. The tool loads with ¥6,500,000 household income, two children, and the all-public school track, producing a default estimate of about ¥16,387,500 per child.
• The baseline blends Japan Cabinet Office child-rearing cost survey data with MEXT's survey of learning expenses, brought forward to 2026 yen using Japanese CPI data.
• Income and family-size adjustments follow the general income-elasticity relationship found in Japanese household spending research.
• School-track adjustment. Sourced directly from MEXT's Survey of Learning Expenses (子供の学習費調査), FY2023 results, published December 25, 2024: an all-public track (kindergarten through high school, 15 years) totals about ¥5,960,000; an all-private track totals about ¥19,760,000, a ratio of about 3.3x. That ratio is applied to this model's education category only; every other category is unchanged by track. All-public and all-private are the honest poles of this range, not a description of a typical or average path — many real families mix tracks by school stage, and this calculator does not attempt to model every combination, only the two ends MEXT actually publishes.
• The education category is deliberately weighted higher at the all-public default (about 30 percent versus roughly 16 to 21 percent in other countries in this series) to reflect the real, well-documented cost of juku and exam-prep attendance on both tracks, not only the private one.
• University costs assume a typical four-year degree at a national university with the student living away from home, modeled identically regardless of school track.
• Free early-childhood-education-and-care policy (ages 3-5 universal since October 2019; ages 0-2 for residents'-tax-exempt households only, both subject to monthly caps) is built into the baseline's childcare assumption, not offered as a separate toggle.
• Japan's child allowance (jido teate), reformed October 2024, is noted but not automatically subtracted, since the amount depends on a child's age, birth order, and the number of children in the household.
• Benefit figures (jido teate, the free-ECE caps) and NISA-related facts change periodically; see the "last reviewed" date in the byline above this article. If you are reading this more than a year after that date, verify current amounts before relying on them for a financial decision.
