The Real Cost of Buying a House in Japan: Every Fee and Tax, Explained

The short answer

Buying a house in Japan costs more than the sticker price. Budget for agent commission (a legally capped percentage — the one cost that's fully knowable up front), registration tax and real estate acquisition tax (both based on the property's official assessed value, not the price you pay — more on that below), stamp duty on the sales contract, and a judicial scrivener's fee for the registration paperwork. None of this is hidden; it is knowable in advance once you know where to look, and we break down every line item with its legal source.

The rule everyone forgets: assessed value, not purchase price

Two of the biggest line items — registration tax and real estate acquisition tax — are calculated on the property's fixed-asset tax assessed value (固定資産税評価額), a value set by the local government for tax purposes, not the price you actually pay. Assessed values are usually lower than market price, but the gap varies by property and area — there is no fixed, official conversion ratio we can responsibly quote you. Your agent or judicial scrivener can tell you the current assessed value once it's on record. Any "total cost" figure online that applies a tax rate straight to the sale price, without this adjustment, is quietly misstating two of your biggest costs.

1. Agent commission (仲介手数料) — the one number the law fixes

Agent commission is capped by a Ministry of Land, Infrastructure, Transport and Tourism (MLIT) notification, not freely negotiated upward. For a property priced over ¥4,000,000, the shorthand ceiling is (purchase price × 3% + ¥60,000) + consumption tax.

Worked example: a ¥30,000,000 house → 30,000,000 × 3% = 900,000; + 60,000 = 960,000; + 10% consumption tax = ¥1,056,000. That is the legal ceiling an agent can charge for representing one side of the deal — agents can charge less, and the fee is something to confirm and put in writing before you sign a brokerage agreement, not to assume.

For lower-priced properties and vacant homes ("空家等") priced at ¥8,000,000 or below, a 2024 revision lets an agent charge up to a flat ¥300,000 (+ tax) to cover the extra legwork of handling a low-value or hard-to-sell property — introduced specifically so agents would stop refusing cheap akiya listings.

2. Registration tax (登録免許税) — paid to register your ownership

When your ownership is registered at the Legal Affairs Bureau, you pay registration tax, calculated on assessed value:

• Land, ownership transfer: standard rate 2.0%; a reduced rate of 1.5% applies under a periodically renewed special measure (most recently extended through March 31, 2029).
• Building, ownership transfer: standard rate 2.0%; a qualifying residence (floor area ≥50㎡, with a municipal certificate, registered within one year of acquisition or construction) can drop to 0.3% — through March 31, 2027.

These reduced rates are time-limited special measures, not permanent law — renewed repeatedly for over a decade, but always confirm the current expiry on the National Tax Agency's page before relying on one, especially near a fiscal year-end.

3. Real estate acquisition tax (不動産取得税) — a one-time bill from your prefecture

A few months after registration, the prefecture sends a one-time acquisition tax bill — again based on assessed value:

• Standard rate: 4%.
• Reduced rate for land and residential buildings: 3%, through March 31, 2027.
• Deductions from the taxable base: ¥12,000,000 off for a new home; a used home gets the same deduction that applied when it was originally built (the exact figure depends on the construction year — ask your agent or the prefectural tax office). Land gets its own separate reduction calculation.

This is genuinely the line item most likely to land near ¥0 for an ordinary family home once the deduction is applied — but don't assume that without checking; it depends on the specific assessed value.

4. Stamp duty (印紙税) on the sales contract

The sale contract itself needs a revenue stamp, at a reduced rate for real estate transfer contracts through March 31, 2027:

• Contract price over ¥10,000,000 up to ¥50,000,000: ¥10,000.
• Contract price over ¥50,000,000 up to ¥100,000,000: ¥30,000.

Small relative to the other line items, but due on signing, so it belongs on your closing-day checklist.

5. Judicial scrivener's fee (司法書士報酬)

A judicial scrivener (司法書士) handles the actual registration filing — and, unlike everything above, their fee is not set by law at all. Fees were deregulated in 2003; each scrivener sets their own. The national federation publishes non-binding reference surveys, but there is no official schedule we can responsibly quote you here. Ask for a written quote before you commit — it is a normal, expected question.

What we're leaving out, and why

Fire/earthquake insurance, a loan-arrangement fee if you're financing, and moving costs are real budget items too, but their amounts are market-set and vary by provider — get quotes rather than trusting a blog's number for these. See our cost calculator for the agent-commission ceiling worked out for your own price, and our note on the non-resident reporting rule if you're buying from outside Japan.

This explains the general fee and tax structure as of 2026-07-15 and is not tax or legal advice. Rates, deductions and expiry dates for special measures change; confirm the current figures for your purchase with your agent, judicial scrivener, or the linked official pages before you budget.
