Can I Afford to Buy a House in Japan? Salary & Affordability Guide 2026
Can you afford to buy a house in Japan on your salary? Use the 5x rule: annual income × 5 = safe price range. Tokyo flats from ¥40M, regional cities from ¥20M. Mortgage costs, affordability calculator, and what foreigners need to know.
One of the most common questions from expats and long-term residents in Japan is: can your salary actually support a mortgage here? With Tokyo condos regularly priced at ¥40–70M and a mortgage system built around 35-year terms, understanding what's truly affordable on your income is essential before making any commitments.
This guide explains the key rules, breaks down realistic numbers, and helps you assess whether buying in Japan makes financial sense for you.
Key Takeaways
- The 5x rule: Safe housing price ≈ annual income × 5 (borrow no more than 7–8x income)
- Debt-to-income ratio: Japanese banks look for under 25–35% of gross annual income
- Foreigners can buy: No legal restrictions, but mortgage access depends on residency status
- True costs: Budget 3–7% on top of purchase price for closing costs
- Tokyo reality: A 2LDK condo in mid-city starts at ¥40–50M
The 5x Rule: How Much House Can You Afford?
A reliable starting point for affordability in Japan is the 5x rule: your safe housing price range is roughly annual income × 5. For a more aggressive but still manageable plan, some buyers stretch to 7x — but this leaves little margin for error.
Annual Income to Safe Price Range
| Annual Income | Safe Price (5x) | Stretch Price (7x) | Monthly Mortgage (5x, 1.5%, 35yr) |
|---|---|---|---|
| ¥4,000,000 | ¥20M | ¥28M | ~¥61,000 |
| ¥5,000,000 | ¥25M | ¥35M | ~¥77,000 |
| ¥6,000,000 | ¥30M | ¥42M | ~¥92,000 |
| ¥7,000,000 | ¥35M | ¥49M | ~¥107,000 |
| ¥8,000,000 | ¥40M | ¥56M | ~¥122,000 |
| ¥10,000,000 | ¥50M | ¥70M | ~¥153,000 |
Assumes 10% down payment, 1.5% variable rate, 35-year term. Monthly figures are approximate.
The catch: These are gross income figures. Your take-home pay in Japan is typically 75–80% of gross after taxes and social insurance. On ¥6M gross, you might take home ¥4.7–4.9M — which means a ¥30M mortgage at ¥92,000/month represents about 22–23% of your actual take-home income. That's tight but manageable.
How the Japanese Mortgage System Works
Standard Terms
Japan's mortgage system has several distinctive features:
- 35-year terms are standard and widely available (from age 20 to max repayment age of 75–80)
- Variable rates are most common: currently around 0.3–1.0% (major banks, 2026)
- Fixed rates: 20-year fixed at ~1.5–2.0%, 35-year fixed at ~2.0–2.5%
- No prepayment penalties on most variable-rate mortgages
Debt-to-Income Ratio (返済負担率)
Japanese banks use the debt-to-income ratio (返済負担率, hensai futan-ritsu) as a key screening criterion:
| Annual Income | Bank DTI Limit (typical) |
|---|---|
| Under ¥4M | 30% |
| ¥4M and above | 35% |
However, passing the bank's DTI limit doesn't mean you'll be comfortable. A DTI of 25% on gross income often translates to 30–33% of take-home pay — which is where things start to feel tight. Aim for under 25% of gross, or better yet, under 25% of your actual take-home income.
Foreigners: Same Rules Apply (With Caveats)
Foreigners are subject to the same mortgage rules as Japanese nationals. Permanent residents (PR) have essentially the same access as Japanese citizens. For non-PR foreigners:
- Some banks require PR or a Japanese co-signer
- Others lend to long-term visa holders (work visa, spouse visa) with stable income
- Down payment requirements may be higher (20–30% instead of 10%)

Reality Check: What Does ¥40M–¥60M Actually Buy?
Tokyo 23 Wards
At ¥40–50M, expect a 2LDK condo (60–70m²) in areas like Nerima, Adachi, Edogawa, or Itabashi — solid residential neighborhoods with good train access. For a 3LDK (75–85m²) in a similar area, budget ¥55–70M.
In premium areas (Minato, Shibuya, Shinjuku), ¥50M buys a smaller 1–2LDK or a dated property needing renovation.
Suburban Tokyo (Kanagawa, Saitama, Chiba)
At ¥30–40M, you can find:
- 3–4LDK detached houses (90–110m²) within 40–60 minutes of central Tokyo
- New-build condos in major suburban stations
This is the sweet spot for families prioritizing space and school environments over proximity to central Tokyo.
Regional Cities (Osaka, Nagoya, Fukuoka)
Property prices are 30–50% lower than Tokyo:
| City | 2LDK Condo (mid-city) | 3LDK Detached House |
|---|---|---|
| Osaka | ¥25–40M | ¥25–35M |
| Nagoya | ¥20–35M | ¥20–30M |
| Fukuoka | ¥20–35M | ¥18–28M |
Regional cities offer significantly more space for the same budget — and for many expats working remotely, they represent compelling value.
Hidden Costs to Factor In
Sticker price is just the beginning. Budget for these on top of your purchase price:
| Cost | Amount |
|---|---|
| Closing costs (total) | 3–7% of purchase price |
| Agent commission | ~3% + tax |
| Registration & stamp taxes | ¥200,000–¥500,000 |
| Mortgage arrangement fee | ¥300,000–¥500,000 (or 0.2–2% of loan) |
| Home inspection | ¥50,000–¥100,000 |
| Property tax (annual) | ¥100,000–¥300,000/year |
| Management fee (condos/月) | ¥15,000–¥30,000/month |
| Maintenance reserve (condos/月) | ¥5,000–¥20,000/month |
| Home insurance (annual) | ¥50,000–¥150,000 |
For a ¥40M condo, expect ¥1.5–2.5M in closing costs alone. This means your actual upfront cash needed is: down payment + closing costs + moving costs.
Example: ¥40M condo, 10% down payment
- Down payment: ¥4,000,000
- Closing costs (5%): ¥2,000,000
- Moving & setup: ¥200,000–¥500,000
- Total cash needed upfront: ¥6.2–6.5M minimum
Signs You May Be Overstretching
Before committing, check whether you're in the warning zone:
Red flags to watch for:
- Debt-to-income ratio over 30% (gross income basis) — leaves little buffer for income changes
- Down payment under 10% — increases monthly payments and creates negative equity risk if prices fall
- Variable rate with no buffer plan — if rates rise 1%, can you still cover the higher payment? (On ¥35M at 35 years, a 1% rate increase adds ~¥10,000–14,000/month)
- Closing costs coming from savings meant for emergencies — you should maintain 3–6 months of living expenses in reserve after closing
- Purchase price over 7x annual income — signals you're at the outer limit of what banks will typically approve, with little margin for error
Before You Decide: Run the Numbers
The most important step before committing to a purchase is to calculate your actual monthly costs — mortgage + management fees + property tax + maintenance — and compare that against your take-home income.
