Getting the Numbers Right Before You Buy
One of the most common mistakes first-time property buyers in Japan make is underestimating the tax and financing costs associated with a purchase. Japan's property tax system has several layers, and the mortgage market — while competitive — has specific requirements that differ from many other countries. This guide walks through the essentials so you can plan with confidence.
Property Taxes in Japan
1. Real Estate Acquisition Tax (不動産取得税)
This is a one-time tax levied by the prefecture when you acquire property. The standard rate is 4% of the assessed value (固定資産税評価額), though the effective rate on land and residential buildings is often reduced to 3% under current legislation. Various deductions are available for newly built homes and primary residences — your judicial scrivener or tax advisor can help you maximize these.
This tax is billed several months after the purchase is complete, which can catch first-time buyers off guard if they haven't budgeted for it.
2. Fixed Asset Tax (固定資産税) & City Planning Tax (都市計画税)
Once you own property, you'll pay fixed asset tax annually. The standard rate is 1.4% of the assessed value for the fixed asset tax, plus up to 0.3% for the urban planning tax (in designated urban areas). These are billed yearly, typically in four installments. The assessed value is generally below the market price, providing some relief.
Newly constructed homes may receive a temporary reduction on the building portion of the fixed asset tax for the first few years.
3. Registration and License Tax (登録免許税)
Paid at the time of purchase to register the property transfer and any mortgage in your name. Rates vary but are generally a percentage of the assessed value. Reduced rates may apply to primary residences meeting certain criteria.
4. Stamp Duty (印紙税)
Applied to the purchase contract itself. The amount depends on the contract value but is relatively modest — typically in the range of ¥10,000–¥60,000 for most residential purchases.
Mortgages in Japan
Types of Mortgage
| Type | Description | Typical Rate |
|---|---|---|
| Variable rate (変動金利) | Rate moves with market. Currently lowest rates. | ~0.3–1.0% |
| Fixed for a period (固定期間選択型) | Fixed for 3/5/10 years, then variable. | ~1.0–2.0% |
| Full fixed rate (全期間固定) | Rate fixed for entire loan term (e.g., Flat 35). | ~1.5–2.5% |
Rates shown are indicative only and subject to change. Check current rates with lenders directly.
Flat 35: Japan's Government-Backed Fixed Mortgage
Flat 35 is a long-term fixed-rate mortgage product backed by the Japan Housing Finance Agency (住宅金融支援機構). It offers rate certainty for the full term (up to 35 years) and is popular with buyers who prefer predictability. It has specific requirements around the property's size and building standards. Notably, some Flat 35 products are available to permanent residents, though the range of options for non-residents is more limited.
Eligibility for Foreign Buyers
Most major Japanese banks require permanent residency (永住権) and proof of stable Japanese income for mortgage eligibility. Buyers without permanent residency have fewer options but are not entirely locked out:
- Some regional banks and shinkin banks may lend to long-term visa holders with strong employment history
- A small number of international banks with Japanese operations offer mortgages to non-resident foreign nationals
- Having a Japanese co-borrower or guarantor can improve eligibility
Mortgage Interest Deduction (住宅ローン控除)
Japan offers a significant mortgage interest deduction for primary residence buyers. Currently, qualifying buyers can deduct a percentage of the outstanding mortgage balance from their income tax liability each year for up to 13 years (for newly built homes meeting energy efficiency standards). This can represent meaningful tax savings over the life of the loan. Eligibility conditions apply — consult a tax advisor to confirm whether you qualify.
Practical Checklist
- Budget 6–10% of purchase price for total transaction costs (taxes, fees, registration)
- Remember the real estate acquisition tax arrives months after settlement — keep funds aside
- Compare variable vs. fixed mortgage rates and model repayment scenarios
- Ask your lender about the housing loan deduction (住宅ローン控除) qualification
- Engage a bilingual tax advisor if you're a foreign national with cross-border tax obligations
The financial side of property ownership in Japan is manageable once you understand the system. Taking the time to plan properly before you commit to a purchase will save you significant stress — and potentially significant money.
