This is a Japan-specific market quirk international buyers should understand before they make an offer: Japan has no equivalent of the US MLS (Multiple Listing Service) or the UK's Land Registry price paid data, where actual sold prices are public and searchable by anyone. Instead, closing prices flow through REINS (Real Estate Information Network System, 不動産流通標準情報システム) — a closed database that only licensed real estate agents can query directly, with a limited public-facing portal for consumers. This information asymmetry is precisely why a straightforward "typical discount is 5-10% off the asking price" rule of thumb, still widely repeated by agents and blogs, is misleading in 2026. Data from the East Japan Real Estate Information Network (東日本レインズ) for June 2026 shows the average asking price per square meter across Greater Tokyo (¥1,165,400/m², approx. US$7,769/m², using this article's ¥150 = US$1 conversion rate as of 2026-08-13) running 41% above the average price condos actually closed at (¥826,400/m², approx. US$5,509/m²). And that 41% figure hides a critical regional split: almost all of the gap is concentrated in Tokyo proper, while in neighboring Chiba Prefecture, asking prices are actually 9.4% below what units are closing at. The meaning of "negotiating room" is the opposite in these two markets.
This article is written for two audiences. The first is a buyer who has a specific unit in front of them right now and needs to decide how large an opening offer (指値, sashine — a formal price offer below asking, the closest Japanese equivalent to a "lowball offer" in Western negotiation, though the practice is normalized and expected here rather than considered aggressive) to submit. The second is a seller who has just received a discount request from a buyer and needs to decide whether to accept it, and when to revise the asking price instead. We use only 2026 primary-source data published by East Japan REINS, Japan's Ministry of Land, Infrastructure, Transport and Tourism (国土交通省, MLIT), the National Tax Agency (国税庁), and the Japan Housing Finance Agency (住宅金融支援機構) to show, in numbers, what percentage a specific ¥3 million (約US$20,000) offer represents by region, how much that discount actually reduces closing costs, and which interest-rate and tax conditions matter more than the negotiation itself. For readers unfamiliar with Japanese residential real-estate transactions, note that "mansion" (マンション) in Japanese real-estate usage means a condominium/apartment unit in a multi-unit building — not a large single-family house, as the English word implies in most Western markets.
Key takeaways of this article
- Greater Tokyo's average asking price per square meter is 41.0% higher than the average price per square meter units actually close at. REINS itself noted in a July 17, 2026 report that this gap between closing price and newly listed price has "widened to approximately 40%."
- Negotiating room is heavily concentrated in Tokyo proper. In Tokyo, asking prices per square meter run 48.8% higher than closing prices, while in Chiba Prefecture they run 9.4% lower — meaning an identical opening offer carries the opposite meaning depending on which side of the prefectural border you're buying in.
- A ¥3 million (approx. US$20,000) opening offer equals 5.8% of the Greater Tokyo average price (¥52.02 million, approx. US$346,800), 4.0% of the central Tokyo wards average (¥75.76 million, approx. US$505,067), and 10.0% of the Chiba Prefecture average (¥29.89 million, approx. US$199,267).
- If a ¥3 million discount is granted, the only closing costs that shrink are the agent's brokerage commission (down ¥99,000, approx. US$660) and, if the sale price crosses a stamp-duty bracket threshold, stamp duty (down ¥20,000, approx. US$133). Registration and license tax and real estate acquisition tax do not decrease by a single yen — because their tax base is the property's fixed-asset tax assessed value, not the actual sale price.
- Whether a market favors negotiation can be measured with a single ratio: months of inventory on the market, calculated as active listings divided by monthly closed transactions. In June 2026 this stood at 10.8 months for Greater Tokyo overall, 12.2 months for Tokyo, and 7.7 months for Chiba.
What Is the Real Discount Rate on a Used Condo in Japan? Testing the "5-10%" Rule Against 2026 Data
The conclusion up front: as of 2026, in Greater Tokyo, it is more useful to measure how far the asking price has drifted from the closing-price baseline than to ask "how many percent off the asking price can I get." The reason is structural — asking prices themselves have moved far away from the prices units are actually closing at, so any percentage applied to an inflated starting point produces a misleading target number.
Why this matters for a foreign buyer specifically: in a market with a public sold-price database like the US MLS or the UK Land Registry, an asking price is a reasonably disciplined anchor because sellers and their agents can see recent comparable closings themselves and price close to them. In Japan, sellers and listing agents set asking prices with only partial visibility into true closing data (REINS access is agent-only, and even agents see a filtered view), which lets asking prices in a rising market drift upward independently of what buyers are actually willing to pay. That drift is exactly what the next section quantifies.
What REINS' Reported "Approximately 40% Gap" Actually Means
According to East Japan REINS' monthly Market Watch summary report (Market Watch サマリーレポート, June 2026 edition, published July 10, 2026), Greater Tokyo's used-condo market breaks into three separate series that are easy to conflate but measure different things. "Closed" (成約) means units that actually sold during the month. "Newly listed" (新規登録) means units newly put up for sale that month. "Active inventory" (在庫) means unsold units still on the market at month-end.
| Series (June 2026, Greater Tokyo) | Units | Price per m² | Price | Floor area | Building age |
|---|---|---|---|---|---|
| Closed (actually sold) | 4,241 units (-1.3% YoY) | ¥826,400/m² (approx. US$5,509/m²) (-0.8%) | ¥52.08 million (approx. US$347,200) (-0.02%) | 63.02 m² | 27.48 years |
| Newly listed (freshly put on market) | 16,277 units (+1.7%) | ¥1,155,700/m² (approx. US$7,705/m²) (+22.0%) | ¥66.26 million (approx. US$441,733) (+20.8%) | 57.33 m² | 29.98 years |
| Active inventory (unsold at month-end) | 45,995 units (+3.5%) | ¥1,165,400/m² (approx. US$7,769/m²) (+28.6%) | ¥67.45 million (approx. US$449,667) (+29.3%) | 57.88 m² | 29.24 years |
Source: East Japan Real Estate Information Network (東日本不動産流通機構, East Japan REINS), "Monthly Market Watch Summary Report, June 2026" (published July 10, 2026)
What stands out is that the closed price per square meter is essentially flat year-over-year, at -0.8%, while the newly listed price per square meter is up 22.0% year-over-year, and active inventory's price per square meter is up 28.6%. The price at which units actually sell hasn't moved. Only the price at which units are offered for sale keeps climbing. For a US or UK buyer used to a market where the "list price" is disciplined by public comparable-sales data, this divergence would be unusual; in Japan it is a structural feature of a market without that public reference point. REINS itself, in its REINS TOPIC "Greater Tokyo Used Condominiums and Used Detached Houses: Long-Term Trend Graphs" (2026年7月17日, July 17, 2026), describes this as: "As the newly listed price per square meter has risen, the recent gap versus the closed price per square meter has widened to approximately 40%."
It would be reasonable to guess that active inventory simply consists of better-quality units that are commanding a premium and therefore taking longer to sell. The data does not support that explanation. Active inventory's average building age is 29.24 years — older than the 27.48-year average for closed units — and its average floor area is 57.88 m², smaller than the 63.02 m² average for closed units. In other words, the units still sitting on the market are, on average, older and smaller than the units that are actually selling, yet they carry a higher price per square meter. Within the same overall market, what sellers believe their units are worth and what buyers are actually paying have pulled apart.
How Should You Treat the "5-10% Discount" Rule of Thumb?
The commonly cited guideline that "used condos typically negotiate for 5-10% off asking" is only meaningful for a property whose asking price is already close to the closing-price baseline. Because a discount percentage is always calculated against the asking price, if the asking price itself is set loosely, no amount of debating the percentage will get you to the actual market level.
Run the numbers for Greater Tokyo's June 2026 averages. Average active-inventory price was ¥67.45 million (approx. US$449,667). Applying the conventional 5-10% discount produces a range of ¥60.71 million to ¥64.08 million (approx. US$404,733–US$427,200). But the average closed price for the same month was ¥52.08 million (approx. US$347,200). Even applying the top end of the conventional range — a full 10% off — still leaves you ¥8.63 million (approx. US$57,533) above the price units are actually closing at. Reaching the closed-price average from the inventory average would require a 22.8% reduction.
This does not mean any single unit can be negotiated down 22.8%. Active inventory and closed sales are different populations of properties with different compositions — if high-priced central units sit on the market longer, the inventory average rises mechanically even with no change in any individual unit's price. The takeaway is narrower but more useful: the entire mental model of "apply a flat percentage discount to the asking price" is a weak starting point in the current market. A more defensible number comes not from a percentage but from the price per square meter of recent closed sales for comparable units — the property type, size, and condition you are actually targeting.
Comparison point for readers used to disclosed sold-price data: in the US, a buyer's agent typically pulls recent "comps" (comparable sold listings) from the MLS in minutes, and the number is verifiable by anyone through county records. In Japan, the equivalent comparable-sales data sits inside REINS Market Information (レインズ・マーケット・インフォメーション), a public-facing portal with real closed transaction data, but it is thinner, less filterable, and slower to update than an MLS — which is exactly why understanding how asking prices drift from closing prices, as this article does, substitutes for the comp-pulling exercise a US buyer would otherwise take for granted. This information gap is also discussed, from a different angle, in our related article on how off-market ("unlisted") property information actually works in Japan.
Negotiating Room Is Concentrated in Tokyo — Not Evenly Spread Across the Region
This is the single most important finding in this article. When the 41.0% gap is broken down by prefecture, negotiating room turns out to be concentrated almost entirely in Tokyo, while in Saitama, Chiba, and Kanagawa Prefectures the relationship actually reverses.
| Prefecture (June 2026) | Closed price/m² | Inventory price/m² | Gap | Months of inventory |
|---|---|---|---|---|
| Tokyo | ¥1,169,100/m² (approx. US$7,794/m²) | ¥1,739,400/m² (approx. US$11,596/m²) | +48.8% | 12.2 months |
| Kanagawa | ¥603,500/m² (approx. US$4,023/m²) | ¥595,500/m² (approx. US$3,970/m²) | -1.3% | 10.0 months |
| Saitama | ¥459,700/m² (approx. US$3,065/m²) | ¥444,900/m² (approx. US$2,966/m²) | -3.2% | 9.9 months |
| Chiba | ¥440,500/m² (approx. US$2,937/m²) | ¥399,000/m² (approx. US$2,660/m²) | -9.4% | 7.7 months |
| Greater Tokyo total | ¥826,400/m² (approx. US$5,509/m²) | ¥1,165,400/m² (approx. US$7,769/m²) | +41.0% | 10.8 months |
Closed price/m² is from Monthly Market Watch Summary Report, June 2026; inventory price/m² and inventory unit counts are from the same month's Data Edition. The gap percentage and months-of-inventory figures are calculated by INA&Associates.
Here is how to read this table. In Tokyo, the average price per square meter currently listed is 48.8% above the average price per square meter units are actually selling for. In practical terms, a buyer in Tokyo who simply accepts the asking price is likely to be paying well above what the market is actually clearing at — this is the prefecture where the "everyone negotiates hard" assumption is most justified by the data. Chiba shows the opposite pattern: its average inventory price per square meter is 9.4% below the closed price, which indicates that a larger share of listed units are priced at or even below the level the market is actually paying. If a buyer approaches a Chiba property with the same aggressive discount expectations that make sense in Tokyo, the seller is likely to simply wait for a different buyer, and the negotiation stalls while a competing offer moves ahead.
One caveat: active inventory and closed sales are different populations of properties (different mix of size, age, and location), so this table does not mean "this specific unit is worth X% less." Read it instead as a regional signal for how far current asking prices, as a group, have drifted from the price level units are actually closing at. For a broader read on how the Greater Tokyo used-condo market is trending overall, our related coverage of closed-transaction trends in the Greater Tokyo used-condo market is a useful companion piece.
How Realistic Is a ¥3 Million (Approx. US$20,000) Discount?
A ¥3 million (approx. US$20,000) figure equals 5.8% in the Greater Tokyo average, 4.0% in the central Tokyo wards, and 10.0% in Chiba Prefecture. The same nominal amount shifts from "rounding to a clean number" to "asking for a discount well outside the norm" depending purely on where the property sits.
What Percentage Is ¥3 Million (Approx. US$20,000), By Region?
The table below calculates what ¥3 million represents as a percentage of regional closed-transaction prices for April-June 2026, based on REINS TOPIC "Greater Tokyo Used Condominiums and Used Detached Houses: Closed Transactions by Area and Building-Age Band [April-June 2026]" (2026年7月17日, July 17, 2026).
| Area (April-June 2026) | Closed price | ¥3M (US$20,000) as a % | Vs. the conventional 5-10% rule |
|---|---|---|---|
| Central Tokyo wards (東京都区部) | ¥75.76 million (approx. US$505,067) | 4.0% | Below the conventional lower bound — a modest ask |
| Yokohama / Kawasaki | ¥43.94 million (approx. US$292,933) | 6.8% | Mid-range of the conventional band |
| Greater Tokyo average | ¥52.02 million (approx. US$346,800) | 5.8% | Near the conventional lower bound |
| Tokyo Tama area | ¥38.82 million (approx. US$258,800) | 7.7% | Above the conventional mid-point |
| Kanagawa (other areas) | ¥30.95 million (approx. US$206,333) | 9.7% | Near the conventional upper bound |
| Saitama Prefecture | ¥30.48 million (approx. US$203,200) | 9.8% | Near the conventional upper bound |
| Chiba Prefecture | ¥29.89 million (approx. US$199,267) | 10.0% | Exactly the conventional upper bound |
Two practical implications follow from this table. First, in the central Tokyo wards, a ¥3 million (US$20,000) opening offer is only 4.0% of market value — actually a fairly modest ask by negotiation standards. Combined with the 48.8% gap discussed in the previous section, Tokyo is an environment where ¥3 million is unlikely, on its own, to strike a seller as an unreasonable demand.
Second, in Saitama, Chiba, and the rest of Kanagawa, ¥3 million reaches roughly a tenth of the average price. These same prefectures also have inventory prices per square meter running below closed prices, and shorter months-of-inventory than the Greater Tokyo average. Opening with a 10%-of-value offer in a market where sellers have little room to concede creates an opening for the seller to simply choose a different buyer.
Building Age Shifts the Whole Price Baseline
Even within the same region, the baseline price shifts by a multiple depending on the building's age band. As a result, what percentage ¥3 million represents ranges from 3.2% to 10.8% depending purely on how old the building is.
| Building age band (Greater Tokyo, April-June 2026) | Closed price | Closed price/m² | ¥3M (US$20,000) as a % |
|---|---|---|---|
| Up to 5 years old | ¥94.48 million (approx. US$629,867) | ¥1,531,000/m² (approx. US$10,207/m²) | 3.2% |
| Up to 10 years old | ¥77.57 million (approx. US$517,133) | ¥1,309,000/m² (approx. US$8,727/m²) | 3.9% |
| Up to 15 years old | ¥79.16 million (approx. US$527,733) | ¥1,244,000/m² (approx. US$8,293/m²) | 3.8% |
| Up to 20 years old | ¥65.36 million (approx. US$435,733) | ¥977,000/m² (approx. US$6,513/m²) | 4.6% |
| Up to 25 years old | ¥65.12 million (approx. US$434,133) | ¥931,000/m² (approx. US$6,207/m²) | 4.6% |
| Up to 30 years old | ¥52.11 million (approx. US$347,400) | ¥767,000/m² (approx. US$5,113/m²) | 5.8% |
| Over 30 years old | ¥27.67 million (approx. US$184,467) | ¥471,000/m² (approx. US$3,140/m²) | 10.8% |
| Total | ¥52.02 million (approx. US$346,800) | ¥831,000/m² (approx. US$5,540/m²) | 5.8% |
Source: REINS TOPIC "Closed Transactions by Area and Building-Age Band [April-June 2026]" (July 17, 2026). "¥3M as a %" calculated by INA&Associates. The source notes that its totals do not precisely reconcile with the closed-unit counts in the Monthly Market Watch Summary Report due to differing aggregation methods.
REINS notes in the same report that units over 25 years old account for more than 50% of all closed transactions in Greater Tokyo. In other words, the majority of used condos actually selling today are more than 25 years old, and in this age band, ¥3 million represents 5.8% to 10.8% of market value. A buyer who applies the same "around ¥3 million feels right" instinct they'd use for a newer building is, without realizing it, demanding roughly a tenth off an older one.
Conversely, requesting ¥3 million off a building five years old or newer is a modest 3.2% adjustment. Even for newer buildings — where negotiating room is often assumed to be tighter — the absolute yen amount is far from trivial. Framing the same negotiation in percentage terms versus a flat yen amount produces two very different impressions of how aggressive the ask is. When presenting an offer to a seller, it is more persuasive to work backward from the price per square meter of comparable closed sales for that specific building-age band and floor area than to lead with a percentage.
What a ¥3 Million Discount Actually Saves — and What It Doesn't
When a discount is granted, how much the associated closing costs shrink varies enormously by cost category. Only the agent's brokerage commission and stamp duty move; registration and license tax and real estate acquisition tax do not fall by a single yen. The table below models the average closed price of ¥52.08 million dropping to ¥49.08 million.
| Cost item | At ¥52.08M (US$347,200) | At ¥49.08M (US$327,200) | Change | Why it moves (or doesn't) |
|---|---|---|---|---|
| Purchase price | ¥52.08 million (US$347,200) | ¥49.08 million (US$327,200) | ▲¥3.00M (US$20,000) | This is the item under negotiation |
| Brokerage commission (statutory cap) | ¥1,784,640 (approx. US$11,898) | ¥1,685,640 (approx. US$11,238) | ▲¥99,000 (approx. US$660) | The portion above ¥4 million is billed at 3.3% of price |
| Stamp duty (reduced-rate) | ¥30,000 (approx. US$200) | ¥10,000 (approx. US$67) | ▲¥20,000 (approx. US$133) | The price crosses the ¥50 million bracket threshold |
| Registration and license tax (登録免許税) | Unchanged | Unchanged | ±¥0 | Tax base is the fixed-asset tax roll value, not the sale price |
| Real estate acquisition tax (不動産取得税) | Unchanged | Unchanged | ±¥0 | Tax base is the standard fixed-asset valuation, not the sale price |
| Total reduction in outlay | – | – | ▲¥3.119M (approx. US$20,793) | ¥3M purchase-price cut + ¥119,000 (approx. US$793) in closing costs |
The brokerage commission calculation: MLIT Public Notice No. 1552 (建設省告示第1552号, last amended June 21, 2024 by MLIT Public Notice No. 949) caps the fee a licensed broker (宅地建物取引業者, real estate transaction business operator) can charge one side of a sale at 5.5% on the first ¥2 million (approx. US$13,333) of price, 4.4% on the portion from ¥2 million to ¥4 million (approx. US$26,667), and 3.3% on the portion above ¥4 million (all figures inclusive of consumption tax). At ¥52.08 million: ¥110,000 + ¥88,000 + ¥1,586,640 = ¥1,784,640. At ¥49.08 million: ¥110,000 + ¥88,000 + ¥1,487,640 = ¥1,685,640. The ¥99,000 (approx. US$660) difference equals exactly 3.3% of the ¥3 million discount — because the entire discount amount falls within the top bracket.
Stamp duty follows National Tax Agency (国税庁, NTA) Tax Answer No. 7108 (reduced stamp-duty rates for real-estate transfer and construction-work contracts): ¥10,000 (approx. US$67) for contracts over ¥10 million (approx. US$66,667) and up to ¥50 million (approx. US$333,333), ¥30,000 (approx. US$200) for contracts over ¥50 million and up to ¥100 million (approx. US$666,667). Dropping from ¥52.08 million to ¥49.08 million crosses that ¥50 million bracket boundary, producing the ¥20,000 (approx. US$133) reduction. Put differently, for a property listed just above the ¥50 million line, whether the price can be negotiated down below ¥50 million determines a 3x swing in stamp duty — a useful negotiating detail in its own right, unrelated to the size of the discount percentage.
Registration and license tax, however, is calculated per National Tax Agency Tax Answer No. 7191 on a tax base defined as "the value registered in the fixed-asset tax roll" (固定資産課税台帳に登録された価格) — not the transaction price. Real estate acquisition tax works the same way: the Tokyo Metropolitan Bureau of Taxation's explanation states explicitly that the tax base "is not the property's purchase price or construction cost," but rather an assessed value calculated under the standard fixed-asset valuation methodology. No matter how much the negotiated sale price falls, these two taxes do not move. The assumption that "a discount proportionally lowers all closing costs" simply does not hold for these two line items — a detail that catches many first-time buyers, domestic and international alike, off guard at settlement.
Comparison for readers used to ad valorem transfer taxes: in many US states and in the UK's Stamp Duty Land Tax, transfer tax is calculated directly on the negotiated sale price, so a lower price mechanically lowers the tax. Japan's registration and license tax and real estate acquisition tax break that intuition — they track a separate, government-assessed property value that moves independently of what a buyer and seller actually agree to pay.
Judging Whether a Market Favors Negotiation Using "Months of Inventory"
"Target a unit that has been listed for three to six months" is a piece of folk wisdom that gets repeated often, but it can be checked against a real number. Months of inventory — how many months it would take to sell off the currently listed stock at the current pace of sales — is that number, and it can be calculated by anyone from public data.
How to Calculate Months of Inventory
The calculation is three steps. Run the same process for whatever area you are targeting, and you can quantify the negotiating environment yourself rather than relying on an agent's characterization of it.
- From the "Data Edition" of REINS' Monthly Market Watch, pull the month-end active-inventory unit count for the prefecture you're targeting.
- Pull the closed-unit count for the same month, from the same data source or the Summary Report.
- Divide the inventory count by the closed-unit count. That is months of inventory.
Using actual June 2026 figures: Greater Tokyo is 45,995 ÷ 4,241 = 10.8 months. Tokyo is 26,120 ÷ 2,136 = 12.2 months. Chiba is 3,909 ÷ 508 = 7.7 months. Saitama is 5,209 ÷ 524 = 9.9 months. Kanagawa is 10,757 ÷ 1,073 = 10.0 months.
The interpretation is straightforward. The longer months of inventory runs, the more a seller is competing against a large pool of similar listings — which, all else equal, strengthens a buyer's negotiating hand. The shorter it runs, the more confident a seller can be that another buyer will appear soon, which weakens their incentive to accept a lowball offer. Within Greater Tokyo, the gap between Tokyo (12.2 months) and Chiba (7.7 months) is 4.5 months. Two markets both labeled "Greater Tokyo used condos" can, in practice, be entirely different negotiating environments.
Tokyo's Inventory Is Building Up, While Saitama, Chiba, and Kanagawa Are Working It Down
It's also worth checking direction, not just level. Year-over-year, active inventory is rising only in Tokyo — the other three prefectures are all shrinking.
| Prefecture (June 2026) | Active inventory (YoY) | Closed units (YoY) | Negotiating environment for buyers |
|---|---|---|---|
| Tokyo | 26,120 units (+12.6%) | 2,136 units (-9.5%) | Inventory rising, sales falling — negotiating room tends to widen |
| Kanagawa | 10,757 units (-6.7%) | 1,073 units (+7.0%) | Inventory falling, sales rising — negotiate cautiously |
| Saitama | 5,209 units (-3.6%) | 524 units (+2.9%) | Inventory falling, sales rising — negotiate cautiously |
| Chiba | 3,909 units (-9.1%) | 508 units (+19.0%) | Steepest inventory decline, strongest sales growth — seller's market |
Source: active inventory from Monthly Market Watch Data Edition, June 2026; closed units from the same month's Summary Report.
Within Tokyo, the central wards stand out further: closed transactions there totaled 1,716 units, down 12.8% year-over-year, a sixth consecutive month of decline. A market where inventory is building up while closings decline is, structurally, a market where a buyer's set of realistic alternatives is expanding — which is exactly the condition under which an aggressive opening offer has the best chance of working. Chiba is the mirror image: closed transactions are up 19.0% year-over-year for a fifth consecutive month, while active inventory is down 9.1%. Units are selling faster and the pool of alternatives buyers can point to is shrinking.
It's also worth noting the broader cyclical picture. According to the Quarterly Market Watch, April-June 2026 (季報Market Watch, published July 17, 2026), closed transactions totaled 11,853 units, down 2.0% year-over-year — the first year-over-year quarterly decline in seven quarters. The closed price averaged ¥52.01 million (approx. US$346,733), up 0.2% year-over-year (a 55th consecutive quarter of year-over-year gains) but down 5.3% from the prior quarter. Read together, this looks like a long uptrend that has recently entered a plateau. That shift in market phase is gradually changing the negotiating backdrop buyers are operating in, even before any single negotiation begins.
Three Public Databases to Check the Market Yourself Before You Negotiate
Telling a buyer to "check comparable closed prices in the area" is not actionable advice unless you know exactly where to look. There are three free, publicly accessible databases available to any individual — even without a real estate license, and in most cases without needing to read Japanese fluently, since the numeric data is legible with basic browser translation. Each serves a different purpose, and using them in sequence is the practical approach.
REINS Market Information (Actual Closed Prices)
REINS Market Information (レインズ・マーケット・インフォメーション, operated by Japan's Designated Real Estate Transaction Organizations) is the consumer-facing portal that publishes actual closed prices — split between condominiums and detached houses — searchable by area, nearest station, floor area, and building age. This is the closest thing Japan has to an MLS sold-price lookup, and it should be the first place you check to answer "what did comparable units near the one I'm targeting actually sell for?" The decisive difference from a listing portal like Suumo or Athome is that this site shows closed prices, not asking prices.

Operated by Japan's Ministry of Land, Infrastructure, Transport and Tourism (国土交通省, MLIT), this site layers actual transaction-price data, official land-price appraisals (地価公示・地価調査), city-planning designations, and disaster-risk information onto a single interactive map. Its distinguishing feature is that it lets you check not just whether the price is reasonable, but what conditions the location itself carries — flood-risk zoning, for instance, is not something a US or European buyer would necessarily think to check separately, but in Japan it is layered directly into this same public tool. This site is less about finding negotiating leverage and more about confirming "is this a location I should be buying in at all, at this price."

MLIT Real Estate Price Index (Long-Term Market Cycle)
The Real Estate Price Index (不動産価格指数) is MLIT's official statistical series tracking real estate prices over time, indexed to 100 as the 2010 average. Tracking the condominium (区分所有, kubun shoyū — sectional/strata ownership, the Japanese legal term for individual condo-unit ownership) index over time shows roughly where the current market sits within its long-term cycle. The most recent published figure puts the seasonally adjusted nationwide condominium index at 225.1 as of December 2025 — meaning prices are running at 2.25 times the 2010 average nationwide. This index cannot be used to price an individual unit, but it is a useful gut-check on whether you are buying into an extended high-price phase or a correction.
One caveat as of this article's publication in August 2026: the most recently published figures cover only through December 2025 (Q4, published March 31, 2026). MLIT has delayed publication of January 2026 data onward, citing a defect in its calculation program. For a real-time read on current market conditions, use REINS' monthly Market Watch reports alongside this index rather than relying on the index alone.

Common Ways Discount Negotiations Fail — and How to Avoid Them
A failed negotiation is not always the result of asking for too much. The failures tend to cluster into three causes: misreading the market environment, showing up without a defensible basis for the number, and getting the sequence of the negotiation wrong.
A Large Opening Offer in a Low-Inventory Area Gets You Bumped to Second Place
This is the single most common failure. In an environment like Chiba's — 7.7 months of inventory, closed transactions up 19.0% year-over-year — the seller has good reason to believe another buyer will show up soon. Opening with ¥3 million (approx. US$20,000) off, roughly a tenth of the average price in that market, means that the moment a different buyer offers full price or a small adjustment, you get leapfrogged.
The countermeasure is to check months of inventory and the year-over-year change in closed transactions before deciding your opening number. In an area where inventory is shrinking and closings are rising, a proposal built around terms — matching the seller's preferred closing date, taking on removal of the seller's remaining belongings yourself — tends to land better than a price-only ask. Conversely, in an area like the central Tokyo wards, where inventory is building up and closings are falling, there is relatively more room to push on price itself.
When a Discount Negotiation Loses to a Rate Move
Spending several months chasing a ¥3 million (US$20,000) discount, only to watch mortgage rates climb 0.1 percentage points in the meantime, is a realistic scenario, not a hypothetical one. Putting the two side by side, in the same units, makes clear where your time is actually best spent.
The assumptions: financing the full ¥52.08 million average closed price with a 35-year, fixed, equal-payment loan at 3.290% annual interest. This rate reflects the most common tier — 21- to 35-year terms, loan-to-value of 90% or below — from the Japan Housing Finance Agency (住宅金融支援機構, JHF)'s Flat 35 (【フラット35】, Japan's dominant long-term fixed-rate mortgage product) rate table for funds disbursed in August 2026.
| Scenario | Loan amount | Rate | Monthly payment | Total repayment | Vs. baseline |
|---|---|---|---|---|---|
| Baseline (no discount) | ¥52.08M (US$347,200) | 3.290% p.a. | ¥208,953 (approx. US$1,393) | approx. ¥87.76M (US$585,067) | – |
| If the ¥3M (US$20,000) discount succeeds | ¥49.08M (US$327,200) | 3.290% p.a. | ¥196,917 (approx. US$1,313) | approx. ¥82.71M (US$551,400) | ▲¥5.055M / US$33,700 (monthly: ▲¥12,036 / US$80) |
| No discount, rate rises 0.1 pt | ¥52.08M (US$347,200) | 3.390% p.a. | ¥211,936 (approx. US$1,413) | approx. ¥89.01M (US$593,400) | +¥1.253M / US$8,353 (monthly: +¥2,982 / US$20) |
Two things follow from this table. First, a successful ¥3 million discount saves ¥5.055 million (approx. US$33,700) over the life of the loan — roughly four times the cost of a 0.1-point rate increase. The negotiation genuinely matters financially; this is not an argument against negotiating.
Second, a 0.1-point rate difference alone moves total repayment by ¥1.253 million (approx. US$8,353). A buyer who spends months exclusively focused on price while deferring the choice of lender or rate type risks giving back on one side what they gained on the other. Negotiating the price and arranging financing should run as two parallel tracks, not sequentially. Note that these figures are estimates; actual costs vary with mortgage life insurance (団体信用生命保険) terms, origination fees, and guarantee-fee structures — all of which a US or European buyer should budget for separately, since Japanese mortgage cost structures differ meaningfully from a standard US fixed-rate closing-cost breakdown. Non-resident and foreign-national buyers should also note separately that Flat 35 and most Japanese bank mortgages have restrictive eligibility rules for non-residents; financing structures for overseas buyers are a distinct topic from the rate comparison shown here.
Getting the Negotiation Sequence Right
Even a well-justified number can fail to land if it arrives in the wrong order. Presenting an offer in the following sequence gives the seller an application that is easy to say yes to.
- Get mortgage pre-approval first. A confirmed pre-approval tells the seller "if we sign with this buyer, the deal is likely to actually close." This single fact does more for the credibility of your opening offer than almost anything else you can present.
- Back your number with comparable closed transactions. Pull closed price per square meter for genuinely comparable units from REINS Market Information and present it as "this price per square meter × this floor area produces this number." A calculation lands better than a percentage.
- Pair the price ask with something that benefits the seller. Matching their preferred closing date, taking on removal of items the seller is leaving behind, or shortening the period between contract and closing are all non-price concessions that can move a negotiation forward.
- Negotiate through the licensed broker, not directly with the seller. Direct buyer-seller communication increases the risk of misunderstandings and "he said, she said" disputes over terms. Routing everything through a documented paper trail protects both sides — and is standard practice in Japan regardless of whether either party is a foreign national.
In 2026, a Building's Energy-Performance Tier Can Matter More Than Price Negotiation
Everything so far has been about negotiating the price down. But for 2026 used-condo purchases, a difference just as large as — or larger than — a successful price negotiation comes from which energy-efficiency tier the building qualifies for, a distinctly Japanese tax mechanism with no close US equivalent. Japan's mortgage tax credit (住宅ローン減税, jūtaku rōn genzei — the Housing Loan Tax Deduction) was extended five years starting with January 2026 move-ins, and the borrowing-limit and deduction-period figures for existing (used) homes were expanded at the same time.
Maximum Deduction by Existing-Home Performance Tier, 2026 Move-Ins
The credit rate is 0.7% of the year-end mortgage balance, and both the borrowing limit eligible for the credit and the number of years it applies differ by the building's certified energy-performance tier. Working through the maximum deduction for each tier:
| Existing-home performance tier | Borrowing limit × years | Max deduction | Child-rearing / young-couple households |
|---|---|---|---|
| Certified long-life quality housing / low-carbon housing (長期優良住宅・低炭素住宅) | ¥35M (approx. US$233,333) × 13 years | ¥3.185M (approx. US$21,233) | ¥45M (approx. US$300,000) × 13 years = ¥4.095M (approx. US$27,300) |
| ZEH-level energy-efficient housing (ZEH水準省エネ住宅) | ¥35M (approx. US$233,333) × 13 years | ¥3.185M (approx. US$21,233) | ¥45M (approx. US$300,000) × 13 years = ¥4.095M (approx. US$27,300) |
| Energy-standard-compliant housing (省エネ基準適合住宅) | ¥20M (approx. US$133,333) × 13 years | ¥1.82M (approx. US$12,133) | ¥30M (approx. US$200,000) × 13 years = ¥2.73M (approx. US$18,200) |
| All other existing housing (その他住宅) | ¥20M (approx. US$133,333) × 10 years | ¥1.40M (approx. US$9,333) | No enhancement available |
Source: MLIT "Overview of FY Reiwa 8 (2026) MLIT Tax Reform" (令和８年度国土交通省税制改正概要, December 2025), which specifies a 0.7% credit rate and an income requirement of ¥20 million (approx. US$133,333) or below. "Child-rearing households" is defined as either a household with a child under 19, or a household where either spouse is under 40.
The gap between the most generous tier and the least generous tier is ¥4.095 million versus ¥1.40 million — a difference of approximately ¥2.70 million (approx. US$18,000). That is nearly the same order of magnitude as the ¥3 million price negotiation this entire article has been analyzing. Winning a ¥3 million discount at the negotiating table and buying into a building with a higher energy-performance certification produce roughly the same scale of household financial impact. For an international buyer accustomed to green-building tax credits functioning as a minor bonus rather than a core purchase-decision variable, this is worth registering: in Japan's 2026 tax regime, it is not a minor bonus.
This deduction figure is a ceiling, not a guarantee. The actual amount claimed is capped by the buyer's year-end mortgage balance and the income tax (plus, for any un-offset remainder, resident tax) actually owed that year — a taxpayer with a smaller tax liability simply cannot claim the full figure. Separately, for existing housing, a building completed on or after January 1, 1982 is automatically treated as meeting the current seismic-standard requirement (新耐震基準, shin-taishin kijun — Japan's post-1981 earthquake-resistance building code, introduced after the 1978 Miyagi earthquake exposed weaknesses in the prior standard). Buildings completed before that date require one of: a seismic-standard compliance certificate, a copy of a construction housing performance evaluation report, or proof of existing-home defect liability insurance (MLIT, Housing Loan Tax Deduction — Acquiring an Existing Home). Given that Greater Tokyo's average closed-unit building age is 27.48 years, and units over 25 years old make up more than half of all closed transactions, most buildings currently on the market fall within the automatic-compliance window — but for anything completed in 1981 or earlier, whether that certificate exists determines whether the deduction is available at all. The income requirement is total income of ¥20 million (approx. US$133,333) or below; the floor-area requirement is 40 m² or above (50 m² or above for buyers with total income over ¥10 million [approx. US$66,667], or anyone using the child-rearing/young-couple enhancement).
We recommend confirming both the certified performance tier and whether the required compliance certificate exists with the listing broker while a property is still being compared against alternatives. Price negotiation depends on the other side agreeing; confirming the performance tier depends only on you. In terms of certainty, this is the point you can act on first. If you plan to carry out energy-efficiency or seismic retrofits after purchase, our companion piece on renovation tax-credit amounts and how to file for them is worth reviewing alongside this section, so you can weigh the full post-purchase cost picture, not just the acquisition price.
How to Think About Price Negotiation as a Seller
The rest of this article shifts to the seller's side. When a buyer requests a discount, or when inquiries have dried up and a price revision is on the table, the input that should drive the decision is whether active inventory is rising or falling in the prefecture your property sits in.
When — and by How Much — to Revise Your Asking Price
As of June 2026, conditions across Greater Tokyo's prefectures are asymmetric. Tokyo's active inventory is up 12.6% year-over-year while closed transactions are down 9.5% (down 12.8% in the central wards specifically). A seller listing in Tokyo is, in effect, waiting for a buyer in a market where the competing supply has grown more than a tenth larger than it was a year ago.
Saitama, by contrast, shows inventory down 3.6% and closings up 2.9%; Chiba shows inventory down 9.1% and closings up 19.0%; Kanagawa shows inventory down 6.7% and closings up 7.0%. Competing supply is shrinking and the pace of sales is accelerating in all three. A seller listing in these three prefectures has considerably less pressure to accommodate a buyer's opening offer quickly than a seller in Tokyo does.
A practical sequence for weighing a price revision:
- Calculate months of inventory for your own prefecture. Active inventory ÷ monthly closed units. For June 2026: Tokyo 12.2 months, Kanagawa 10.0 months, Saitama 9.9 months, Chiba 7.7 months.
- Check whether active inventory is rising or falling year-over-year. A rising trend means competing supply is growing, and conditions may deteriorate the longer you wait.
- Compare your own asking price per square meter against closed price/m² for the same area and building-age band. Across Greater Tokyo overall, active-inventory price/m² runs 41.0% above closed price/m². Whether your listing sits above or below that regional average shapes how overpriced a buyer will perceive it to be.
- Track inquiry and viewing counts over time. Measuring the effect of a price change requires a documented baseline from before the change.
How to respond to a buyer's offer is best decided by comparing it against how many months it would likely take to find the next buyer if you decline. In a market with more than 12 months of inventory, the ongoing cost of waiting — management fees (管理費), the building's repair reserve fund contribution (修繕積立金), and property tax — accumulates while you wait for a better offer. In a market with fewer than 8 months of inventory, holding out has more genuine justification. This is a comparison of time and money, not a decision to be made on instinct.
INA&Associates' View: Negotiation Isn't the Art of Haggling — It's the Work of Assembling Evidence
We sit between buyers and sellers on price conversations every day, and one thing we have come to believe firmly is this: what separates a negotiation that closes from one that falls apart is not the size of the number — it's whether that number is backed by evidence.
"I hear the going rate is 5-10% off, so please reduce ¥3 million" lands very differently with a seller than "comparable units near the same station, roughly 30 years old and around 65 m², are closing at ¥767,000/m² (approx. US$5,113/m²), which puts a fair value on this unit at roughly ¥49.86 million (approx. US$332,400)." The first is a buyer's wish. The second is a proposal grounded in observable market fact. Sellers, in turn, usually need to explain a price reduction to a spouse, family, or their own internal calculus — and a number with evidence behind it makes that conversation easier for them, too.
The other principle we hold to is telling clients the downside up front, not after the fact. That registration and license tax and real estate acquisition tax do not fall even when a discount succeeds. That a 0.1-point rate move is worth ¥1.253 million (approx. US$8,353) over the loan's life. That the gap between energy-performance tiers is worth roughly ¥2.70 million (approx. US$18,000). These are the kinds of facts that, discovered only after a deal is signed, tend to breed regret. We believe that surfacing them before the decision, so a client can weigh them alongside everything else, is what builds trust over the long run — a principle that matters even more, not less, when the client is transacting across a language and legal system that is not their own.
A real estate transaction is never a single win-or-lose event. The property you buy will eventually be sold again someday, and the proceeds from a sale flow into whatever comes next — another property, another investment. That is why we frame information not around the discount achieved in a single negotiation, but around how the purchase will be judged ten years from now. As a company that treats its people (人財, jinzai — a term Japanese companies use to signal that staff are viewed as an asset to be cultivated, not simply "human resources" to be allocated) as its most important asset, we build our service on the principle that the person handling your transaction can explain the numbers behind every recommendation in their own words.
Frequently Asked Questions (FAQ)
What is the typical discount rate on a used condo in Japan?
There is no single flat percentage that applies across the board. As of June 2026, in Greater Tokyo, active-inventory price per square meter runs 41.0% above closed price per square meter, meaning the conventional "5-10% off" guideline falls well short of actual closing levels for a large share of listings. Regional variation is wide: in Tokyo, inventory prices run 48.8% above closed prices, while in Chiba they run 9.4% below. Rather than starting from a flat percentage, we recommend working backward from the closed price per square meter of genuinely comparable units.
Can you realistically get a ¥3 million (approx. US$20,000) discount on a used condo in Japan?
It depends heavily on region and building age. ¥3 million equals 4.0% of the central Tokyo wards' average closed price of ¥75.76 million (approx. US$505,067), and 10.0% of Chiba's average closed price of ¥29.89 million (approx. US$199,267). It's 5.8% of the Greater Tokyo average, and 10.8% for buildings over 30 years old. In the central Tokyo wards, where inventory is building up, ¥3 million is a fairly modest ask. In Chiba, where months of inventory sits at 7.7 and closed transactions are up 19.0% year-over-year, the same amount is likely to be treated as an aggressive request equal to roughly a tenth of market value.
If a negotiation succeeds, how much do closing costs actually go down?
If the price drops from ¥52.08 million to ¥49.08 million, only the brokerage commission (down ¥99,000, approx. US$660) and stamp duty (down ¥20,000, approx. US$133) shrink, for a combined ¥119,000 (approx. US$793). The brokerage commission moves proportionally because the portion above ¥4 million is billed at 3.3% of price; stamp duty falls because the new price crosses below the ¥50 million bracket threshold. Registration and license tax and real estate acquisition tax, however, do not change at all, since their tax base is the fixed-asset tax assessed value rather than the transaction price. Combined with the ¥3 million price reduction itself, total savings come to ¥3.119 million (approx. US$20,793).
As a seller, how should I respond to a buyer's discount request?
Base the decision on months of inventory and the year-over-year change in active-inventory count for your own prefecture. As of June 2026, Tokyo's inventory is up 12.6% year-over-year with closings down 9.5%, while Chiba's inventory is down 9.1% with closings up 19.0% — essentially opposite conditions. In a market where inventory is rising, waiting tends to bring more competing supply, not less. It helps to weigh how long it would realistically take to find another buyer if you decline the offer against the ongoing cost of waiting — management fees, repair reserve fund contributions, and property tax accrue the entire time the unit remains unsold.
