Key Takeaways
- In Japan, the price on a listing is not the price buyers actually pay
- Official government data shows actual sold prices are typically 10–20% below asking
- The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) publishes real transaction prices — this data is free and public
- Most foreign buyers never see this data and accept listing prices at face value
- This single fact changes how you should evaluate every property in Japan
The Price You See Is Not the Price People Pay
If you've browsed Japanese property listings on Suumo, Homes.co.jp, or Real Estate Japan, every price you've seen is an asking price — the seller's desired price, not the market price.
This is not unusual in real estate globally. But Japan has a feature that most foreign buyers overlook: the government publishes actual transaction prices for properties across the country. When you compare these two data sets — listing prices versus what buyers actually paid — a consistent gap emerges.
That gap is typically 10–20%, depending on the area and property type.
For a foreign buyer evaluating a ¥60,000,000 listing, this means the actual market value may be closer to ¥48,000,000–54,000,000. The difference is not trivial — it can represent millions of yen and fundamentally alter whether a property is a good investment.
The Data: How Big Is the Gap?
JRE compiles MLIT transaction data for major investment areas. When we compare median sold prices per square meter against average listing prices on public portals, the pattern is consistent across Tokyo, Osaka, and resort markets.
| Area | Listing Avg (¥/m²) | MLIT Sold Median (¥/m²) | Gap |
|---|---|---|---|
| Shinjuku | ~¥1,550,000 | ¥1,311,111 | -15% |
| Roppongi / Azabu | ~¥2,250,000 | ¥1,925,000 | -14% |
| Shibuya | ~¥1,600,000 | ¥1,342,857 | -16% |
| Osaka (Namba) | ~¥1,150,000 | ¥966,667 | -16% |
| Niseko (Kutchan) | ~¥650,000 | ¥520,000 | -20% |
| Fukuoka (Tenjin) | ~¥950,000 | ¥810,000 | -15% |
Methodology note: Listing averages are estimated from publicly available portal data (Suumo, Real Estate Japan) for condominiums in each area. MLIT median figures are from JRE's compiled transaction records. These are area-level comparisons — not matched-pair analyses of identical properties. Individual properties will vary based on condition, floor, age, and specific location within the area.
The gap is smallest for new construction in prime central Tokyo (5–10%) and largest for resort properties and older buildings in regional cities (15–25%).
Why the Gap Exists
The asking-sold price gap is not a market inefficiency waiting to be exploited. It is a structural feature of how Japanese real estate operates.
Asking prices reflect seller hopes, not market reality
In Japan, the seller sets the listing price in consultation with their agent. There is no formal appraisal requirement for listings. Sellers naturally anchor high — they want the best possible outcome and often factor in emotional attachment, renovation costs they've spent, or the price they originally paid.
Negotiation is built into the system
Unlike some markets where listing at market value is the norm, Japanese real estate pricing assumes negotiation will occur. A listing price includes a negotiation buffer that both parties understand exists. Offering below asking is not insulting — it is expected.
Dual agency creates misaligned incentives
Japan permits dual agency (両手仲介 / ryoute chuukai), where a single agent represents both buyer and seller. In this structure, the agent earns commission from both sides — and that commission is calculated as a percentage of the sale price. The incentive to maximize the transaction price is real, even when it may not serve the buyer's interest.
Foreign buyers lack price references
Domestic Japanese buyers often have a sense of local pricing through years of exposure — neighborhood gossip, comparable sales, real estate advertisements. Foreign buyers arriving from markets with transparent sold-price data (the US has Zillow/MLS, Singapore has URA caveats, Australia has CoreLogic) find themselves in an information vacuum. Listing prices become the only reference point.
Portals only show asking prices
No major Japanese property portal — Suumo, Homes.co.jp, at home, Real Estate Japan — displays actual transaction prices. The data exists in the MLIT database but is published separately and requires effort to access and interpret. This information asymmetry benefits sellers and agents who prefer buyers not to comparison-shop against real transaction records.
How to Check Actual Sold Prices
The process is straightforward once you know it exists.
Step 1: Identify your target area
Narrow your search to a specific ward, district, or neighborhood. The more specific, the more useful the comparison.
Step 2: Check MLIT transaction data on JRE
JRE's Location pages compile official MLIT transaction records for each area, showing median price per square meter, price trends over time, and the distribution of actual sold prices by building age and property type.
Step 3: Calculate the asking price per square meter
Take any listing price and divide by the property's floor area. A ¥58,000,000 listing for a 55m² unit equals ¥1,054,545/m².
Step 4: Compare against the MLIT median
If the MLIT median for that area and building age range is ¥880,000/m², the listing is priced approximately 20% above recent transactions.
Step 5: Use the gap as a starting point
A 20% gap does not automatically mean you should offer 20% less. But it tells you the listing is priced significantly above where similar properties have actually traded — and that gives you a data-backed basis for negotiation. For a step-by-step negotiation framework, see our negotiation guide for foreign buyers.

Real Example: Evaluating a Minato-ku Listing
Consider a hypothetical but realistic scenario to illustrate the process.
Property: Minato-ku, 18 years old, reinforced concrete (RC), 55m² Asking price: ¥58,000,000 (¥1,054,545/m²)
Step 1: Check MLIT transaction data for Minato-ku condos in the 15–20 year age range. Result: Median sold price is approximately ¥880,000/m².
Step 2: Calculate the gap. ¥1,054,545 vs ¥880,000 = the listing is approximately 20% above the transaction median.
Step 3: Assess what might justify a premium. Does the property have features that warrant paying above median — a high floor, corner unit, recent renovation, proximity to the station? If yes, some premium is justified. If it is an average unit on a mid-floor with no renovation, the data suggests a fair offer would be closer to ¥48,400,000 (¥880,000 × 55m²).
Step 4: Frame your offer with data. Rather than guessing or anchoring to the asking price, you now have a reference point grounded in official government records. This changes the conversation from "I want a discount" to "MLIT data shows comparable transactions at this level."

Where This Data Comes From
The MLIT (Ministry of Land, Infrastructure, Transport and Tourism / 国土交通省) has been collecting actual transaction price data since 2005 through the Real Property Transaction Price Information system (不動産取引価格情報). After a property transaction is completed, the buyer receives a questionnaire from MLIT asking about the transaction details — price, area, building age, structure type, and more.
The response rate is approximately 30–40%, which means the database does not capture every transaction. However, with over 4.8 million records accumulated, it provides a statistically robust picture of actual market prices across Japan.
Key characteristics of the data:
- Updated quarterly — new records are published approximately 3–6 months after the transaction
- Covers all property types — condominiums, detached houses, land, and commercial properties
- Includes location, size, age, structure, and price — enabling meaningful comparisons
- Free and public — available through the MLIT website and compiled by platforms like JRE
This is not appraisal data or estimated values. These are prices that real buyers actually paid in completed transactions.
Limitations: What This Data Cannot Tell You
Using MLIT transaction data effectively requires understanding what it does not do.
It is not a property-by-property match. The median for an area represents the typical transaction, not the specific property you are evaluating. A unit with a panoramic view on the 30th floor of a premium tower will justifiably trade above the area median. A ground-floor unit facing a wall will trade below it.
Property condition varies. Two units in the same building with the same floor area can have vastly different values if one has been fully renovated and the other has not been updated in 20 years. MLIT data does not capture interior condition.
The gap is not a guaranteed discount. A 15% gap between listing and MLIT median does not mean every buyer gets 15% off. Some listings are already priced at or below the median. Others have legitimate reasons for a premium. The data provides direction, not a formula.
Timing matters. MLIT data has a 3–6 month lag. In rapidly moving markets, recent transactions may not yet be reflected in the published data.
Use it as a compass, not a calculator. The value of this data is in revealing the general direction and magnitude of the asking-sold gap — not in producing a precise "correct" price for any individual property.
What This Means for Your Purchase
Understanding the asking-sold gap changes your approach to buying property in Japan in several concrete ways:
-
You stop anchoring to listing prices. Once you know that asking prices systematically overshoot actual transactions, you evaluate properties against MLIT data rather than the number on the listing.
-
You negotiate from knowledge. Instead of guessing at a reasonable offer, you can reference specific transaction data for the area. Agents take data-backed offers more seriously.
-
You avoid overpaying. The most expensive mistake a foreign buyer can make in Japan is paying the listing price for a property that similar buyers purchased for 15% less. MLIT data makes this visible.
-
You can compare areas accurately. Listing prices across different neighborhoods are set by different sellers with different motivations. MLIT transaction medians give you an apples-to-apples comparison of where buyers actually transact.

Frequently Asked Questions
Where does MLIT transaction data come from?
The Ministry of Land, Infrastructure, Transport and Tourism sends questionnaires to property buyers after transactions are completed. Approximately 30–40% of buyers respond, providing details on the actual sale price, property size, age, structure type, and location. This data has been collected since 2005 and now includes over 4.8 million records. JRE compiles and presents this data for each location to make it accessible to foreign investors.
Is this the same as an appraisal?
No. MLIT data reflects actual prices paid in completed transactions — not estimated values. A formal appraisal (不動産鑑定) is conducted by a licensed appraiser and considers the specific property's condition, location within a building, and comparable sales. MLIT transaction data provides the market context that an appraisal sits within, but is not a substitute for a property-specific valuation.
Does the asking-sold gap apply to new construction too?
The gap is smallest for new construction, typically 3–8%. Developers price new units based on detailed market analysis and construction costs, leaving less room for negotiation. The gap is larger for resale properties (10–20%) where individual sellers set prices with more variability.
Can my agent access this data?
Yes. The MLIT database is publicly available and any licensed agent can access it. However, agents rarely volunteer this information to buyers — particularly foreign buyers — because it reveals that listings are priced above market. If your agent is not using transaction data to help you evaluate properties, that tells you something about whose interests they are prioritizing.
How often is MLIT data updated?
MLIT publishes new transaction data quarterly, with a lag of approximately 3–6 months from the transaction date. JRE updates its Location pages as new data becomes available. For the most current picture, check both the MLIT median and the date range of the most recent transactions shown.
