Public Housing Rent & Income Rules in Japan
Unlike private apartments, Japanese public housing rent is not fixed—it is individually calculated based on household income, building age, and location.
Learn how statutory monthly income (Seirei Gesshu) is computed, allowable tax deductions, standard vs. discretionary ceilings, and compare rules with JKK and UR housing.
1. How Income-Based Rent Works ("Ono-Oeki" Rent System)
In Japanese public housing (Toei, Ken-ei, Shi-ei), rent is not a fixed market price. Under Article 16 of the Public Housing Act, rent is governed by the "Ono-Oeki" rent system, which recalculates each household’s monthly rent annually based on ability to pay (income) and benefit received (unit size, age, and location).
Statutory Rent Calculation Formula (Enforcement Order Art. 2)
Monthly Rent = Base Rent Benchmark × Municipal Location Factor × Floor Area Factor × Building Age Factor × Convenience Factor
- Base Rent Benchmark (Income Tier): National benchmark corresponding to your statutory income bracket (tiers 1 to 6 below).
- Municipal Location Factor: Reflects regional land price levels across Japan (higher in Tokyo/Yokohama, lower in rural towns).
- Floor Area Factor: Calculated by dividing exclusive living area by standard area (65 m²). Larger units have a higher factor.
- Building Age Factor: Reduces rent progressively as the building ages.
- Convenience Factor: Set by local ordinances (0.5 to 1.3) based on station walking distance, elevator availability, and surrounding amenities.
National Income Tiers & Base Rent Benchmarks
| Income Tier | Statutory Monthly Income (Seirei Gesshu) | Base Rent Benchmark (Monthly) | Estimated Actual Rent (After Multipliers) |
|---|---|---|---|
| Tier 1 | ¥0 to ¥104,000 | ¥34,400 | Approx. ¥15,000 – ¥25,000 / month |
| Tier 2 | ¥104,001 to ¥123,000 | ¥39,700 | Approx. ¥20,000 – ¥32,000 / month |
| Tier 3 | ¥123,001 to ¥139,000 | ¥45,400 | Approx. ¥25,000 – ¥38,000 / month |
| Tier 4 | ¥139,001 to ¥158,000 | ¥51,200 | Approx. ¥30,000 – ¥45,000 / month |
| Tier 5 (Discretionary) | ¥158,001 to ¥186,000 | ¥58,500 | Elderly, disabled, and child-rearing households |
| Tier 6 (Discretionary) | ¥186,001 to ¥214,000 | ¥67,500 | Elderly, disabled, and child-rearing households |
2. Statutory Income Ceilings (Standard ¥158,000 vs. Discretionary ¥214,000)
Under Article 23 of the Public Housing Act, all applicants must meet strict national income ceilings to be eligible for public housing:
🏠 Standard Households: Ceiling ≤ ¥158,000 / month
Applies to the majority of general applicants (Tiers 1 to 4).
- If your net statutory monthly income after deductions exceeds ¥158,000, you are legally ineligible for standard public housing.
- Approximate gross salaried annual income limits:
- Single individual: Gross approx. ≤ ¥2,960,000 / year
- 2-person household (1 dependent): Gross approx. ≤ ¥3,500,000 / year
- 3-person household (2 dependents): Gross approx. ≤ ¥3,980,000 / year
- 4-person household (3 dependents): Gross approx. ≤ ¥4,470,000 / year
🌟 Discretionary Households: Ceiling ≤ ¥214,000 / month
Relaxed upper threshold for vulnerable and priority households (Enforcement Order Art. 6).
- Elderly Households: Applicant is age 60+, and all cohabitants are age 60+ or under age 18.
- Disability Households: Household members possessing physical, intellectual, or psychiatric disability certificates.
- Child-Rearing Households: Households raising children who have not yet finished preschool (up to age 6, or in some municipalities up to high school age).
- Gross salaried annual income limit (3-person, 2 dependents): Up to approx. ¥4,970,000 / year.
3. Step-by-Step Calculation of Statutory Monthly Income (Seirei Gesshu)
Statutory monthly income is not your monthly take-home pay or your raw gross salary. It is strictly computed according to the formula in Enforcement Order Article 1, Paragraph 3:
Statutory Monthly Income = ( Total Annual Gross Income of All Members − Total Statutory Deductions ) ÷ 12 Months
※Fractions under ¥100 are rounded downStep 1: Calculate "Gross Income" (Shotoku Kingaku) for All Members
For salaried employees, find the "Income After Employment Income Deduction" (Kyuyo Shotoku Kojo Go no Kingaku) on your Withholding Tax Slip (Gensen Choshuhyo). If multiple household members work, sum their respective net incomes.
Step 2: Subtract All Applicable Statutory Deductions
Deduct legal allowances for each cohabitant and dependent (¥380,000 per dependent, plus special allowances for single parents, disabilities, and young adults aged 16–22).
Step 3: Divide by 12 and Check Eligibility
Divide the net amount by 12. If the resulting figure is ¥158,000 or less (or ¥214,000 for discretionary households), you qualify. The exact figure designates your rent tier (Tier 1 through 6).
4. Table of Statutory Deductions (Dependents, Single Parents, Disabilities)
Statutory deductions permitted under Article 1, Paragraph 3 of the Public Housing Act Enforcement Order:
| Deduction Item | Amount Deducted | Statutory Conditions |
|---|---|---|
| Employment / Pension Income Deduction | Up to ¥100,000 per earner | Deducted from each person earning wage income or public pension income (tax reform adjustment). |
| Cohabiting & Dependent Relative Deduction | ¥380,000 per person | Applied for every cohabiting relative and dependent non-applicant (spouse, child, elderly parent). |
| Specified Dependent Relative Deduction | Additional ¥250,000 (Total ¥630,000 with dependent deduction) | For dependents aged 16 to 22 (high school and university student age). |
| Elderly Dependent Relative Deduction | Additional ¥100,000 (Total ¥480,000 with dependent deduction) | For dependent parents or grandparents aged 70 or older. |
| General Disability Deduction | ¥270,000 per person | Applicable for household members with recognized physical, psychiatric, or intellectual disabilities. |
| Special Disability Deduction | ¥400,000 per person | For members with Grade 1–2 physical disabilities or severe intellectual/psychiatric conditions. |
| Single Parent (Hitorioya) Deduction | ¥350,000 | Single mother or father supporting a dependent child (total income ≤ ¥5,000,000). |
| Widow (Kafu) Deduction | ¥270,000 | Unmarried or bereaved women supporting dependents (total income ≤ ¥5,000,000). |
5. Income Excluded from Calculation (Welfare, Unemployment, Overseas Remittances)
Under the Public Housing Act, social safety net payments and student allowances are classified as non-taxable support and are counted as ¥0 in income calculations:
✅ Incomes Counted as ¥0 (Do NOT Include)
- Public Assistance (Seikatsu Hogo): Housing assistance, living assistance, and education allowances.
- Unemployment & Leave Benefits: Employment insurance basic allowances, childcare leave benefits, nursing leave benefits.
- Survivor & Disability Pensions: Non-taxable government pension disbursements.
- Child Allowances (Jido Teate): Municipal and national welfare child allowances.
- Family Living Remittances: Financial support sent from family abroad to foreign students or dependents.
- Educational Scholarships: JASSO scholarships and university grants.
⚠️ Mandatory Incomes (MUST Include)
- Salaries & Wages: Full-time, part-time, dispatched, and contract salaries, including all bonuses and overtime pay.
- Old-Age Pensions: Taxable national and welfare old-age pensions.
- Business & Rental Income: Net income from self-employment, freelancing, or property management.
6. What Happens if Your Income Increases After Moving In?
If your household income rises during tenancy due to wage increases or new employment, strict provisions under Articles 28 and 29 of the Public Housing Act take effect:
1. Excess Income Tenants (Shunyu Choka-sha, Art. 28)
- Trigger: Living in public housing for 3 or more years and exceeding the statutory ceiling (¥158,000 / ¥214,000).
- Consequence: You are legally placed under an "obligation to make effort to vacate" (Akewatashi Doryoku Gimu), and an additional surcharge (Warimashi Chintairyo) is levied, increasing your monthly rent.
2. High-Income Tenants (Kogaku Shotoku-sha, Art. 29)
- Trigger: Living in public housing for 5 or more years, with statutory monthly income exceeding ¥313,000 for 2 consecutive years (equivalent to approx. ¥8,000,000+ gross salaried annual income).
- Consequence: The prefecture or municipality issues an official eviction order (Akewatashi Seikyu) with a set deadline. Rent increases to full private-market equivalent rent ("Kinbo Doshu Chintairyo"). Failure to vacate results in legal eviction proceedings.
7. Public Housing vs. JKK Housing vs. UR Rental Housing
If your income exceeds public housing limits, or if you prefer a transparent market-based contract without annual income filings, consider JKK corporate rentals or UR rental housing:
| Criterion | Public Housing (Toei/Ken-ei/Shi-ei) | JKK Housing (Corporate) | UR Rental Housing |
|---|---|---|---|
| Rent Determination | Income-Subsidized ("Ono-Oeki") Recalculated annually based on income | Fixed Market Rent Fixed standard rent | Fixed Market Rent Fixed standard rent |
| Upper Income Ceiling | Strictly Enforced ≤ ¥158,000 (discretionary ≤ ¥214,000) | None (no maximum limit) | None (no maximum limit) |
| Minimum Income Floor | None (¥0 income or welfare eligible) | Enforced Approx. 3x–4x monthly rent or ¥200k–¥250k/mo | Enforced Approx. 4x monthly rent or ¥250k–¥400k/mo |
| Qualifying via Bank Savings | Not allowed (must qualify by annual income) | Allowed (100x monthly rent in savings) | Allowed (100x monthly rent in savings) |
| Post-Move-In Income Rises | Rent surcharges & eviction orders apply | No impact (can stay indefinitely) | No impact (can stay indefinitely) |
