Realistic Cost of Living: Family of Four
The cost of living for a family in Japan centers on one housing decision and one schooling decision, with everything else filling in around them.1 Get those two right and a family of four can plan a Tokyo budget between roughly 330,000 and 600,000 yen per month before international schooling, or 500,000 to over 1,000,000 yen with it (as of September 2026; confirm current figures with the Statistics Bureau and ward offices cited below).21
Procedures, fees, and requirements can change. Confirm current details at the Statistics Bureau of Japan, the Ministry of Education, Culture, Sports, Science and Technology (MEXT), the Japan Pension Service, and your local ward or city office.
Overview
This article budgets for two adults and two children living in Tokyo, the case most prospective movers ask about.1 National statistics anchor the picture: in 2025, two-or-more-person households spent 314,001 yen per month on average, while workers households spent 346,297 yen (as of 2025, released 2026-02-06; confirm current figures with the Statistics Bureau).2
Those national averages cover households of under three members outside Tokyo as well as inside it. A Tokyo family of four runs higher, driven by rent and schooling. The sections below price each line separately, then sum two budget pictures at the end.
Housing: Rent for a 2LDK or 3LDK
Rent is the largest line and the most location-sensitive one in this budget. A family-sized 2LDK (two bedrooms plus living, dining, and kitchen) or 3LDK in Tokyo spans 120,000 to 250,000 yen per month in the content-plan scope, a band late-2025 market data supports for outer and mid-range wards (as of 2025-11-06; confirm current listings with property portals).3
Ward offices do not set rents, so confirm any specific figure against current listings rather than treating a ward average as a quote. The gradient below uses At Home market data as of November 2025.
Central vs outer wards
Central wards command a steep premium over outer family wards. A 3LDK averages 515,600 yen in Minato, 425,500 yen in Shibuya, and 352,200 yen in Chuo, against 156,300 yen in Adachi, 171,700 yen in Nerima, and 154,500 yen in Edogawa (as of 2025-11-06).3
The 2LDK gradient runs flatter: 412,800 yen in Minato at the top, 188,500 yen in Setagaya in the middle, and 126,400 to 147,700 yen across Edogawa, Adachi, Nerima, and Itabashi (as of 2025-11-06).3
A second portal sample from May 2026 reads the outer-ward 3LDK higher, at 200,000 to 250,000 yen with a 23-ward median of 298,400 yen, a reminder that asking-price samples move with listing mix (as of 2026-05).1 Families trading a central address for an outer ward routinely cut this line by 100,000 yen or more.
| Unit | Ward tier | Monthly rent | As of | Notes |
|---|---|---|---|---|
| 2LDK | Outer (Adachi, Nerima, Edogawa, Itabashi) | 126,400-147,700 JPY | 2025-11-063 | Most affordable 23-ward family stock |
| 2LDK | Mid-range (Setagaya, Nakano, Ota) | 166,000-188,500 JPY | 2025-11-063 | Popular family wards |
| 3LDK | Outer (Adachi, Nerima, Edogawa, Itabashi) | 154,500-178,400 JPY | 2025-11-063 | Fits the scope band comfortably |
| 3LDK | Mid-range (Setagaya, Nakano, Ota) | 215,800-245,500 JPY | 2025-11-063 | Upper end of the scope band |
| 3LDK | Central (Minato, Shibuya, Chuo) | 352,200-515,600 JPY | 2025-11-063 | Above the scope band |
Listing-wide averages tell the same story of a rising market. LIFULL HOME'S put the family-oriented average listing rent in the 23 wards at 242,781 yen in October 2025 and 248,669 yen in December 2025 (as of 2025-12).4
Adachi, Nerima, Edogawa, and Itabashi offer 2LDK and 3LDK units near or below 150,000 yen, often with good park and school access. Start the search there before assuming the budget needs central-ward money.3
What the listing rent excludes
The monthly rent is only part of what a lease signing costs. Deposits, key money where charged, agent fees, and guarantee-company fees commonly total several months of rent before a family receives the keys.1
Resident guides describe planning four to six times the monthly rent at move-in, so a 200,000 yen unit can demand 800,000 to 1,200,000 yen upfront (figures reported 2026-05; treat as a planning rule of thumb, not an official schedule).1 Families arriving with exactly one month of rent plus flights run short at the signing table.
Food and Groceries
A family of four spends 70,000 to 120,000 yen per month on food in the content-plan scope. The national anchor sits inside that band: average household food outlay ran toward 90,000 to 94,000 yen per month by late 2025 (as of 2025; confirm current figures with the Statistics Bureau).21
Shopping patterns move a family within the band more than appetite does. Discount chains with mostly home cooking land near the bottom, mainstream supermarkets in the middle, and import-heavy baskets at the top, with two or three family restaurant meals a week adding roughly 25,000 to 50,000 yen (as of 2026-05).1
| Pattern | Monthly food cost | As of | Notes |
|---|---|---|---|
| Home cooking, discount chains | 70,000-95,000 JPY | 2026-051 | OK Store, Gyomu Super, Seiyu pattern |
| Mainstream supermarkets | 90,000-110,000 JPY | 2026-051 | Life, Ito-Yokado, Maruetsu pattern |
| Import-heavy mix | 120,000-160,000 JPY | 2026-051 | Exceeds the scope band; listed for contrast |
Utilities and Connectivity
Electricity, gas, and water for a family unit run 18,000 to 30,000 yen per month in the content-plan scope. Tokyo family estimates center on 20,000 to 28,000 yen for the three utilities, with summer air conditioning and winter heating pushing peak months higher (as of 2026-05; confirm current tariffs with your retailer and water bureau).1
Internet and phones sit on top of that line. Family fiber plus four mobile lines runs roughly 15,000 to 25,000 yen per month on low-cost carriers, higher on major-carrier plans (as of 2026-05).1
| Item | Monthly cost | As of | Notes |
|---|---|---|---|
| Electricity, gas, water | 18,000-30,000 JPY | 2026-051 | Seasonal peaks exceed the average |
| Internet plus four mobile lines | 15,000-25,000 JPY | 2026-051 | Low-cost carriers at the bottom |
Transit and Commuter Passes
A working-parent 定期券 (teikiken, "commuter pass") plus childcare-zone family transit runs 15,000 to 25,000 yen per month in the content-plan scope. The pass itself typically costs 5,000 to 15,000 yen depending on distance and is often employer-reimbursed, with a spouse and children adding roughly 5,000 to 15,000 yen combined for a car-free rail-based household (as of 2026-05).1
This article budgets for no car, the standard Tokyo family pattern. A car adds parking of 15,000 to 50,000 yen per month in central locations plus a 車検 (shaken, "mandatory vehicle inspection") of 100,000 to 200,000 yen every two years (as of 2026-05).1
Schooling: Public vs International
Schooling is the budget fork. The public path is functionally free at the tuition level, while the international path costs 2 to 3 million yen per year per child in tuition alone at most day schools, with premium upper years running higher (as of 2026-04 tuition tables; confirm current fees with each school).56
Every figure in this section is per child, and entrance fees, bus charges, lunches, and trips stack per head. Two children roughly double the schooling line rather than sharing it.5
Public school path
Public elementary and junior high tuition is free, including for foreign-resident children. Families still pay ancillary costs such as lunches of around 4,500 to 5,500 yen per month per child plus supplies, uniforms, and trips, totaling roughly 120,000 to 190,000 yen per year per child (as of 2026-03 reporting of the MEXT survey).6
High school adds MEXT's 就学支援金 (shugaku shienkin, "high-school tuition support fund"). The fund pays households with a high-school student paying less than 304,200 yen in municipal graded income tax (a model household under 9.1 million yen annual income), at 9,900 yen per month for standard full-time high schools, with higher multiples for eligible private-school households by income band.7
Survey averages show how far the private path diverges even before international schools enter the picture.
Annual averages run 352,566 yen public versus 1,666,949 yen private at elementary level, 538,799 yen versus 1,436,353 yen at junior high, and 512,971 yen versus 1,054,444 yen at high school, for a 15-year total of 5.7 million yen public against 18.4 million yen private (as of the FY2023 MEXT survey, reported 2026-03).6
International school path
Typical day-school tuition runs 1.5 to 3.8 million yen per year, with major Tokyo high schools at 2.7 to 3.8 million yen (as of 2026-04 fee tables; confirm current fees with each school).5
A 12-year run at 2 million yen per year totals about 24 million yen, and top-tier rates push past 36 million yen.5
First-year costs run higher than the headline tuition. Registration and enrollment fees of 250,000 to 500,000 yen are typical, with premium schools charging 900,000 to 1,350,000 yen, plus annual facility charges, bus fees, lunches, uniforms, and exam fees on top (as of 2026-04).56
| Item | Annual cost | As of | Notes |
|---|---|---|---|
| Public school ancillary costs, per child | 120,000-190,000 JPY | 2026-036 | Lunches, supplies, uniforms, trips |
| High-school tuition support, standard full-time | 9,900 JPY/month | current MEXT page7 | Income-tested; see MEXT page |
| International day-school tuition, per child | 1,500,000-3,800,000 JPY | 2026-045 | Major Tokyo high schools 2.7-3.8M |
| International registration, first year | 250,000-500,000 JPY typical; 900,000-1,350,000 premium | 2026-0456 | One-time, per child |
Insurance and Pension
Health insurance plus pension runs 40,000 to 80,000 yen per month combined in the content-plan scope. The mix depends on employment type: employees split employees insurance with their employer, while self-employed or non-employed household members pay municipal National Health Insurance plus flat-rate National Pension.8910
National Pension charges every enrolled adult a flat monthly premium. The premium is 17,510 yen for FY2025 (April 2025 to March 2026) and 17,920 yen for FY2026, so two adults on National Pension pay 35,040 yen per month in FY2025 terms (as of 2026-04-01; confirm current premiums with the Japan Pension Service).8
National Health Insurance (国民健康保険, kokumin kenko hoken, "National Health Insurance") works differently from employees insurance. Each municipality sets its own formula on prior-year income, charges a per-capita levy for every enrollee with no dependent concept, and caps each component annually.910
Itabashi Ward's FY2026 formula shows the mechanics: the medical portion takes 7.51 percent of prior-year base income plus 47,600 yen per enrollee (cap 670,000 yen), the support portion 2.80 percent plus 17,600 yen per enrollee (cap 260,000 yen), the care portion 2.43 percent plus 17,800 yen per enrollee aged 40 to 64 (cap 170,000 yen), and the child-support portion 0.27 percent plus 1,800 yen per enrollee plus 73 yen per adult enrollee (cap 30,000 yen), with preschool children paying half the medical and support per-capita levies (as of FY2026; confirm current rates with your ward office).9
Nationally the FY Reiwa-7 levy cap totals 1,090,000 yen per year across the three main portions (as of FY2025/2026 reporting).10
Adachi Ward's worked examples show what the formula means in practice. A 30-year-old with 2 million yen of prior-year income pays about 234,000 yen per year, and with 3 million yen about 339,000 yen per year (as of FY2026 examples; confirm current figures with your ward office).11 Income scaling plus per-head levies is why the family band spans 40,000 to 80,000 yen per month once pension joins the line.
| Item | Cost | As of | Notes |

Miscellaneous: Extracurriculars and Family Life
Clubs, lessons, family entertainment, and child clothing and supplies run 30,000 to 60,000 yen per month in the content-plan scope. National data points the same way: culture and recreation services spending rose in real terms through 2025 (as of 2025; confirm current figures with the Statistics Bureau).21
One child in weekly lessons can consume half this band alone. After-school cram schools add a common extra on top: monthly fees of 8,000 to 40,000 yen per subject can reach 100,000 to 400,000 yen per year across subjects (as of 2026-09 reporting).6
Monthly Totals: Two Budget Pictures
The public-schooling picture sums the six lines above to roughly 330,000 to 600,000 yen per month (component as-of dates as stated in each section; confirm current figures with the sources cited).2839111 Outer-ward rent with home cooking sits near the bottom, while mid-range wards with mainstream shopping sit near the top.
International schooling adds roughly 170,000 to 250,000 yen per month per child in tuition alone, that is 2 to 3 million yen per year divided by twelve (as of 2026-04 tuition tables).5 One child in international school pushes the family toward 500,000 to 850,000 yen per month, and two children toward 700,000 to over 1,000,000 yen, before entrance fees and recurring extras.5
| Picture | Monthly total | As of | Notes |
|---|---|---|---|
| Family of four, public schooling | 330,000-600,000 JPY | 2026-092839111 | Six-line sum |
| One child in international school | 500,000-850,000 JPY | 2026-0951 | Plus first-year entrance fees |
| Two children in international school | 700,000-1,000,000+ JPY | 2026-0951 | Per-child fees compound |
Good to know
The year-two residence-tax bill lands on top of this budget
Residence tax bills prior-year income starting in June of the following year, so a mid-year arrival pays little or nothing in year one and meets the first full bill in year two. That bill sits entirely outside the monthly bands above, which is why new arrivals budgeting exactly to these lines feel ambushed the second June.
Setting aside a tax reserve from month one, rather than treating the first quiet year as the normal cost level, prevents the surprise from becoming a shortfall.
Health insurance premiums follow prior-year income
National Health Insurance uses the same prior-year logic ward by ward, with different rates in each municipality and a per-capita levy for every family member (FY2026 Itabashi and Adachi figures; confirm current rates with your ward office).911 A family moving wards between years can see the premium change without any income change at all.
Employees on employer-split insurance face a steadier deduction instead. Knowing which scheme each earner belongs to matters more than the headline band.
Move-in costs equal several months of rent
Deposits, key money where charged, agent fees, and guarantee-company charges cluster at signing, commonly four to six times the monthly rent on a family unit (planning pattern reported 2026-05).1 A 200,000 yen lease can therefore demand 800,000 to 1,200,000 yen before the keys change hands.
Arriving with flights plus one month of rent covered is not arriving with the move covered. Hold the signing fund separate from the monthly budget.
International-school fees compound per child
Tuition of 1.5 to 3.8 million yen per year reads as one line until a second child enters the same school, at which point entrance fees, capital levies, bus charges, and trip fees all double too (as of 2026-04 fee tables).5 Twelve years at 2 million yen per year totals about 24 million yen for one child, not for the family.5
Families weighing this path should price every child through graduation, including the first-year entrance fees, before comparing it against the public-schooling picture.
