SUMMARY
Partly yes. Central Tokyo condos are already showing bubble-like behavior, but Tokyo as a whole still has enough real demand, supply scarcity and rental growth to stop short of a full citywide bubble call.
The biggest warning is not one record price. It is the overlap between record new-condo pricing, double-digit land appreciation in prime wards and unusually high short-term reselling in the same central areas.
Headline new-build averages exaggerate the boom because supply has become tiny and luxury-heavy. The ¥142.49 million first-half average is meaningful, but monthly figures can be distorted badly by a handful of ultra-expensive launches.
The resale market is the useful reality check. Existing condos in the 23 wards are rising much more slowly than new units, while Greater Tokyo resale prices have recently been roughly flat year on year and inventory has been increasing.
Affordability is where the market looks most stretched. Prices have moved far faster than household incomes and rents over the past five years, so buyers are increasingly paying for scarcity and expected appreciation rather than current cash flow.
Foreign buyers matter most where Tokyo is already hottest. Their overall share remains modest, but the concentration in central wards and Shinjuku is high enough to influence pricing in the exact submarkets where new towers, prestige and flipping activity are strongest.
Speculation is no longer just anecdotal. A 19.6% one-year resale rate for new Shinjuku condos is hard to explain as ordinary household turnover, especially in a market where launch lotteries can create immediate resale premiums.
Higher mortgage rates are arriving at an awkward moment. Tokyo prices reached record levels under much cheaper financing, and the market now has to prove it can hold those valuations while long-term fixed borrowing costs are materially higher.
The strongest argument against a crash is scarcity. New-condo launches are at a multi-decade low, construction costs are high, Tokyo is still gaining residents and rents are rising, so this is not a classic oversupply boom waiting to implode.
The practical conclusion is a split market: central new and recently built condos look increasingly bubble-like, while outer wards and much of the resale market look expensive rather than detached from fundamentals. If financing keeps tightening while central prices continue outrunning rents and incomes, the bubble case will become much harder to dismiss.

Why does Tokyo property suddenly look so overheated?
Tokyo property looks much more bubble-like today because record condo prices, fast-rising central land values and visible speculative reselling are now happening at the same time.
The most obvious change is in new condominiums. According to the Real Estate Economic Institute, the average new condo sold in Tokyo's 23 wards during the first half of 2026 reached ¥142.49 million, up 9.1% from a year earlier and another record. Across Greater Tokyo, the average crossed ¥100 million for the first time over a six-month period.
The land underneath those apartments is also becoming more expensive. Tokyo Metropolitan Government's latest official survey showed residential land values across the 23 wards rising 9.0% year on year. Minato jumped 16.6%, Taito 14.2% and Shinagawa 13.9%.
Then there is the behavior of buyers. A Ministry of Land, Infrastructure, Transport and Tourism study found that 9.3% of new condos in the 23 wards were resold within one year. The share reached 12.2% across six central wards and 19.6% in Shinjuku.
Any one of those numbers could have a reasonable explanation. Put together, they show Tokyo has entered a different phase from the slow, yield-driven property market investors were used to a decade ago.
| Tokyo indicator | Latest reading | Comparison | What we see |
|---|---|---|---|
| New condo average, 23 wards | ¥142.49m | +9.1% YoY | Record pricing |
| Residential land, 23 wards | +9.0% | +7.9% previously | Growth accelerating |
| Minato residential land | +16.6% | +12.7% previously | Very fast prime appreciation |
| New condos resold within one year | 9.3% | 12.2% in six central wards | Speculative activity |
| Shinjuku short-term resale share | 19.6% | Nearly 1 in 5 | Clearly abnormal turnover |
Are Tokyo condo prices really rising as fast as people think?
Tokyo condo prices are rising fast, but some of the craziest numbers you see today exaggerate what is happening to the typical apartment.
The first-half average of ¥142.49 million in the 23 wards is useful because it covers six months rather than one unusually expensive launch. A 9.1% annual increase at that price level is already substantial.
Monthly averages can be much more misleading. At one point this summer, the average price of newly released condos in the 23 wards jumped to roughly ¥265 million, close to double the level a year earlier. Tokyo apartments obviously did not become twice as valuable in twelve months. A small number of extremely expensive projects changed the mix of what was sold.
The resale market gives us a useful comparison. Recent REINS transaction data put resale condos in the 23 wards at roughly ¥1.36 million per square metre, only around 2.7% higher than a year earlier.
So the Tokyo condo boom is real, but the underlying market is moving much more slowly than the most dramatic new-build headlines suggest.
| Market measure | Latest level | Recent change | What it tells us |
|---|---|---|---|
| New condos, 23 wards, first half | ¥142.49m average | +9.1% YoY | Strong genuine inflation |
| One recent monthly new-condo average | ~¥265m | Almost double YoY | Distorted by project mix |
| Resale condos, 23 wards | ~¥1.36m/m² | +2.7% YoY | Much calmer |
| Residential land, 23 wards | — | +9.0% | Broader appreciation |
Don't buy the wrong property, in the wrong area of Tokyo
Buying real estate is a significant investment. Don't rely solely on your intuition. Gather the right information to make the best decision.
Are luxury developments making Tokyo look more expensive than it really is?
Yes, Tokyo's luxury condo boom is pushing the headline average much higher than the price movement experienced by ordinary apartments.
New-condo supply has collapsed while what remains has shifted upward in quality and price. Greater Tokyo saw only 21,962 new condominium units launched in 2025, according to the Real Estate Economic Institute. That was the lowest annual figure since its survey began in 1973.
With so few homes reaching the new-build market, individual luxury projects can move the average dramatically. The six central wards already averaged close to ¥195 million per new apartment in 2025.
We can see the same statistical effect outside central Tokyo. Chiba's average new-build condo price recently jumped 56.8%, largely because expensive projects in Funabashi entered the sample. That did not mean the average existing apartment in Chiba suddenly became 57% more valuable.
Tokyo therefore has two things happening together. Real property inflation is pushing prices higher, while the shrinking supply of ordinary new condos makes the published new-build average look even more spectacular.
Are Tokyo resale condos starting to cool?
Tokyo resale condos are still expensive, but recent resale data look far calmer than the new-build market and give us the clearest evidence that the boom is not equally intense everywhere.
REINS data recently put the completed resale price in the 23 wards at around ¥1.36 million per square metre, up about 2.7% year on year. Across Greater Tokyo, completed resale prices per square metre were roughly flat year on year during the second quarter.
Transaction activity has softened too. Completed resale deals have fallen in some recent comparisons while listings available for sale have increased.
Compare that with new condos in the 23 wards, which averaged roughly ¥2.23 million per square metre during the first half of 2026. The datasets cover different properties and slightly different periods, so we should not treat the gap as a clean like-for-like discount. Even so, the difference is enormous.
New-build buyers are currently paying a very large premium for scarcity, modern specifications, tower amenities and prime locations. Existing apartments have not followed at anything close to the same speed.
That weakens the case for calling all Tokyo property a bubble. The hottest part of the market is much narrower.
| Segment | Approximate level | Recent movement | Current temperature |
|---|---|---|---|
| New condos, 23 wards | ~¥2.23m/m² | Strongly higher | Very hot |
| Resale condos, 23 wards | ~¥1.36m/m² | +2.7% YoY | Warm |
| Greater Tokyo resale price/m² | ~¥0.83m/m² | Roughly flat YoY in Q2 | Cooling |
| Greater Tokyo resale inventory | Rising | More homes for sale | Less seller-friendly |

Have Tokyo property prices outrun rents and incomes?
Yes, Tokyo property prices have run far ahead of rents and incomes, and this is probably the strongest evidence that valuations are becoming stretched.
UBS's latest Global Real Estate Bubble Index puts Tokyo in its high-risk category with a score of 1.59, second only to Miami among the 21 cities studied.
The more interesting part is why. UBS estimates that inflation-adjusted Tokyo housing prices rose roughly 35% over five years. Real rents and real household incomes moved only by low-to-mid single digits over the same period.
Rents have improved lately. Savills recorded meaningful rental growth across the 23 wards, including annual increases above 8% during part of 2025 and continued gains afterward. That confirms that tenants are genuinely competing for housing.
But the long-term gap remains huge. Housing values have risen several times faster than the cash flow those properties produce and much faster than the earnings of the people expected to buy them.
Once prices depend increasingly on buyers believing that another buyer will accept an even higher valuation later, we are moving closer to bubble territory.
Can normal Tokyo salaries still support current condo prices?
For many local households, new Tokyo condos are now simply too expensive to be supported by salaries alone.
Take the current ¥142.49 million average new condo in the 23 wards. A household earning ¥10 million a year would be looking at a purchase price equivalent to more than fourteen years of gross income, before income tax, mortgage interest, management fees and other living costs.
UBS reaches a similar conclusion from another angle. Its affordability comparison estimates that a skilled service worker would need more than ten years of income to buy a representative 60-square-metre Tokyo apartment.
That might have been easier to absorb when Japanese mortgages were extraordinarily cheap. Borrowing costs are moving against buyers now.
The Housing Finance Agency currently shows a standard Flat 35 fixed rate of 3.46% for 21-to-35-year mortgages with a loan-to-value ratio of 90% or less. The same benchmark was 3.14% in July. Borrowers eligible for specific discounts can get lower introductory rates, but the underlying long-term fixed cost has clearly moved higher.
Affordability is worsening from both directions: Tokyo homes are expensive relative to incomes, and financing those prices is getting noticeably harder.
Buying real estate in Tokyo can be risky
An increasing number of foreign investors are showing interest. However, 90% of them will make mistakes. Avoid the pitfalls with our comprehensive guide.
Are foreign buyers pushing Tokyo property into bubble territory?
Foreign buyers are adding meaningful pressure to prime Tokyo property, especially in central condos, but they are nowhere near large enough to explain the whole boom.
A Ministry of Land, Infrastructure, Transport and Tourism survey found buyers registered at overseas addresses accounted for around 3.5% of new condo purchases in the 23 wards during the first half of 2025.
The central wards look very different. The share reached 7.5% across six core wards and 14.6% in Shinjuku.
That concentration is more important than the Tokyo-wide average. Overseas buyers tend to compete for the same kinds of properties: new towers, prestigious neighborhoods, units near major stations and apartments that can work as investments or second homes.
Currency has helped as well. Years of yen weakness made Tokyo look relatively inexpensive to people whose wealth is held in dollars, Singapore dollars, Hong Kong dollars or other stronger currencies, even while the same apartment became much less affordable to a Japanese salaried household.
Foreign capital is therefore amplifying the price pressure where Tokyo is already hottest. We would struggle to blame overseas buyers for a citywide bubble, but in some premium submarkets their effect is clearly much larger than a 3.5% headline share suggests.
| Area | Overseas-address share of new condo purchases | What that means |
|---|---|---|
| Tokyo 23 wards | ~3.5% | Small citywide share |
| Central six wards | ~7.5% | Much more important |
| Shinjuku | ~14.6% | Large enough to affect pricing |
| Most Tokyo purchases | Domestic buyers | Foreign demand cannot explain everything |
Are people actually flipping Tokyo condos now?
Yes, short-term condo flipping in central Tokyo has become common enough that we can no longer dismiss it as a niche behavior.
The clearest evidence comes from the MLIT study of new condominium resales. Across the 23 wards, 9.3% of newly purchased condos were sold again within a year. Six central wards reached 12.2%, while Shinjuku hit 19.6%.
A nearly one-in-five short-term resale rate is hard to explain through ordinary life events such as divorce, relocation or changing family circumstances.
There is another reason this matters. New condos are often sold through lotteries when demand heavily exceeds supply. A buyer who secures a scarce unit can sometimes resell it quickly at a premium. That turns access to a new launch into something closer to an asset-allocation opportunity than a normal home purchase.
Short-term resales alone do not prove that prices will fall. They do show that appreciation expectations are affecting buyer behavior already.
Shinjuku's 19.6% rate is especially difficult to reconcile with a purely owner-occupier market.

Is rising interest finally becoming a problem for Tokyo property?
Yes, rising borrowing costs are becoming a real problem for Tokyo property because buyers now have to absorb higher mortgage rates after years of huge price increases.
The change is visible in fixed mortgages. The standard Flat 35 rate for a 21-to-35-year loan is currently 3.46% for borrowers meeting the main loan-to-value condition. It was 3.14% only a couple of months earlier.
That difference sounds small until we apply it to Tokyo-sized mortgages.
On a ¥100 million loan over 35 years, moving from roughly 2% financing to the mid-3% range changes the monthly payment by tens of thousands of yen. On top of today's record purchase prices, that is enough to remove some households from the market altogether.
Variable mortgages remain cheaper for many borrowers, which is why Tokyo has not suddenly frozen. But those rates have also moved upward as the Bank of Japan has left the zero-rate world behind.
The timing makes the next phase unusually interesting. Tokyo's biggest property boom in decades now has to survive financing costs that are materially higher than the ones that helped prices get here.
| Financing measure | Earlier environment | Current situation | Effect on buyers |
|---|---|---|---|
| BOJ policy setting | Near-zero rates | Positive and much higher | Less cheap liquidity |
| Flat 35, 21–35 years | Around 2% in earlier periods | 3.46% standard rate currently | Higher monthly payments |
| July Flat 35 benchmark | 3.14% | 3.46% now | Still rising |
| Variable mortgages | Extremely cheap | Rising gradually | More rate risk |
Is Japan building up dangerous property debt again?
Japan's real-estate credit is heating up, but we still do not see the kind of financial excess that made the late-1980s property bubble so dangerous.
The Bank of Japan's latest Financial System Report says real-estate-related lending is growing faster than lending overall. The share of real-estate loans on bank balance sheets has also been trending upward, with more exposure going to property companies and real-estate funds.
That deserves attention. Rising property values combined with faster lending can reinforce each other if banks start treating ever-higher real-estate prices as justification for still more credit.
Yet the same Bank of Japan assessment says there are currently no major imbalances in Japan's domestic financial cycle. Housing-loan delinquency rates have not shown a meaningful deterioration, and the BOJ still describes banks as broadly prudent in their credit management.
The risk today is narrower: Tokyo property valuations can become too high without the whole Japanese banking system becoming reckless.

Why is Tokyo building so few new condos?
Tokyo is building remarkably few new condos because land, labor and construction have become expensive enough that developers increasingly need luxury-level selling prices to make projects work.
Greater Tokyo recorded only 21,962 new condominium launches in 2025. According to the Real Estate Economic Institute, that was the lowest annual number since the survey began in 1973.
That scarcity does a lot of work in today's market.
Developers compete for limited central land. Japan's construction industry is short of workers. Building materials and wages have become more expensive. When the total development cost rises, producing an ordinary ¥50 million or ¥60 million central apartment becomes difficult.
Developers naturally respond by building fewer units at higher prices, often with better specifications and in locations where wealthy buyers can absorb the cost.
Japan's famous stock of vacant homes does little to solve this problem. An old detached house in a shrinking provincial town cannot substitute for a modern condo near a major Tokyo station. Even an empty house in an outer Tokyo neighborhood may be a poor substitute for someone who needs to commute to Marunouchi, Shibuya or Shinagawa.
Scarcity explains a real part of Tokyo's price boom. It does not tell us whether ¥140 million-plus averages are reasonable, but it makes the market much harder to compare with a classic oversupply-driven housing bubble.
Are Tokyo rents rising fast enough to justify these property prices?
Tokyo rents are rising quickly by Japanese standards, but they still do not justify how far ownership prices have moved.
Savills has recorded some of Tokyo's strongest rental growth in years. At one point in 2025, average rents across the 23 wards were running more than 8% above the previous year. Central wards were close to 9%.
More recently, rental growth has remained positive even as that pace cooled. That tells us demand from actual residents is strong. Population inflows, higher construction costs and limited new rental supply are all showing up in what tenants pay.
The problem appears when we zoom out.
UBS estimates that inflation-adjusted Tokyo home prices are roughly 35% above their level five years earlier. Real rents have increased by only a fraction of that.
An investor buying an apartment today therefore receives less rental income for each yen spent on the property than several years ago. Part of the return buyers are accepting now has moved away from rent and toward expected future capital gains.
That is where we become more cautious.

Is Tokyo's growing population strong enough to keep prices up?
Tokyo's population growth is strong enough to support housing demand right now, and this is one of the best arguments against treating today's market as pure speculation.
Japan is shrinking, but Tokyo is still gaining residents.
Official resident-register data put Tokyo's population at roughly 14.08 million at the beginning of 2026, around 75,000 higher than a year earlier.
Foreign residents accounted for most of that increase. Their number rose by more than 62,000, or about 8.7%, to roughly 784,000. Tokyo also continues to attract Japanese residents from other prefectures, particularly younger workers and students.
That creates real pressure on housing in the neighborhoods where newcomers actually want to live.
The contrast with national demographics is important. Japan can lose population overall while Tokyo gains households because people continue concentrating in the country's dominant employment and education center.
Longer term, Tokyo cannot ignore Japan's shrinking population forever. But anyone expecting the city's property market to collapse simply because Japan has fewer people is currently looking at the wrong geographic level.
Is the Tokyo property boom mostly a central-city problem?
Yes, the most bubble-like part of Tokyo property is concentrated in central wards, even though prices are rising across much of the city.
Tokyo Metropolitan Government's latest land survey shows residential values increasing in every one of the 23 wards. So this is clearly broader than Minato luxury towers.
The speed varies enormously.
Minato residential land rose 16.6%. Taito gained 14.2% and Shinagawa 13.9%. Outer wards such as Katsushika, Edogawa and Nerima were closer to 5% to 6%.
Actual apartment prices show an even wider gap. Recent government transaction data put resale prices around ¥2 million per square metre in Minato compared with roughly ¥625,000 in Adachi in some recent samples.
The hotter wards also overlap with the areas where foreign purchasing, new luxury towers and short-term resale activity are strongest.
Talking about a single "Tokyo bubble" hides too much. The risk rises sharply as we move toward scarce, high-status, highly investable central property.
| Ward or area | Residential land growth | Typical market character | Current risk |
|---|---|---|---|
| Minato | +16.6% | Ultra-prime, global buyers | Very high |
| Taito | +14.2% | Central, strong demand | High |
| Shinagawa | +13.9% | Major jobs and transport hub | High |
| Nerima | +6.2% | Outer residential | Moderate |
| Edogawa | +5.7% | More affordable outer ward | Moderate |
| Katsushika | +5.6% | More affordable outer ward | Moderate |

Are Tokyo property buyers starting to say no to these prices?
Yes, buyers are showing more resistance now, and transaction data are beginning to look softer than the price headlines.
The Real Estate Economic Institute reported that Greater Tokyo's initial-month contract rate for new condominiums fell to 63.9% in 2025. That was the second consecutive year below the 70% level traditionally regarded as healthy for the new-build market.
Resale activity has softened in recent periods too, while available inventory has moved higher.
Property markets rarely go straight from record prices to visible price cuts. Sellers often resist lowering prices, particularly when they are wealthy or under little pressure to sell.
The first change tends to appear in liquidity. Fewer people transact. Listings accumulate. Homes take longer to sell. Buyers become more selective.
Some of that is visible in Tokyo now.
It does not tell us that a crash has started. It does tell us that sellers no longer have unlimited pricing power across the entire metropolitan market.
Is Tokyo today really comparable with Japan's 1980s property bubble?
Tokyo has rediscovered some of the speculative behavior seen during Japan's old property bubble, but today's financial system is nowhere near the excess of the late 1980s.
The similarities are easy to spot. Prime land values are rising at double-digit rates. Some buyers flip new condos almost immediately. Property credit is expanding faster than overall bank lending. Expectations of future appreciation have clearly become part of the buying decision.
The scale is completely different.
During the old Japanese bubble, land became central to an enormous credit loop. Higher land prices created more collateral, that collateral supported more borrowing, and fresh borrowing pushed land values higher again. Estimates of Japanese land wealth eventually reached several times annual GDP.
Today's banks face tighter supervision, stronger capital requirements and much more disciplined risk management. The Bank of Japan's latest Financial System Report explicitly says it sees no major domestic financial imbalance at present.
Interest rates are also moving upward these days, which makes leverage harder rather than progressively easier.
The 1980s comparison is still useful, but mainly as a warning about investor psychology. Tokyo is showing some familiar speculative habits without recreating the credit machine that made the earlier bubble so destructive.

What could actually make Tokyo property prices fall?
Tokyo property could correct without Japan entering a deep recession because today's valuations leave less room for disappointment in interest rates, investor demand or resale liquidity.
Mortgage rates are the clearest pressure point. As pointed out above, the standard Flat 35 long-term rate has moved to 3.46%, and higher borrowing costs directly reduce what households can afford.
Speculative demand is another. Flipping works beautifully while buyers assume a scarce condo will be worth more next year. If resale premiums disappear, people buying mainly for appreciation can leave much faster than owner-occupiers.
Foreign demand could weaken too. A materially stronger yen would make Tokyo property more expensive in overseas currencies and remove part of the advantage international buyers have enjoyed.
Then there is resale supply. New construction can remain scarce while the overall market loosens if investors start listing existing units. The recent increase in resale inventory is therefore more important than another record asking price in a luxury tower.
Tokyo does not need all of these things to happen at once. With prices this stretched relative to incomes and rents, two or three moving in the wrong direction could be enough to flatten prices or produce meaningful declines in the most expensive segments.
So, is Tokyo property in a bubble right now?
Partly yes. Central Tokyo condos are already in bubble-risk territory today, while the broader Tokyo property market still has enough real demand and supply scarcity to stop us from calling it a full citywide bubble.
The strongest evidence is the gap between prices and fundamentals. UBS puts Tokyo second among the 21 cities in its latest global bubble-risk ranking, with a score of 1.59. Inflation-adjusted home values have risen roughly 35% over five years while real rents and incomes have moved far less.
Speculation is no longer anecdotal either. Almost one in five new Shinjuku condos in the MLIT study was resold within one year. Central land prices are rising in double digits, and new condos in the 23 wards now average more than ¥140 million.
We would be much more worried if the same excess were visible everywhere.
It isn't. Resale price growth is much slower. Greater Tokyo resale data have recently shown softer transaction volumes and rising inventory. Tokyo is still gaining residents. Rents are rising. New-condo supply is at a multi-decade low. Construction costs are genuinely high. And the Bank of Japan still sees no major financial imbalance comparable with the machinery behind Japan's late-1980s crash.
The split is pretty clear.
The bubble is already visible in parts of Tokyo, especially new and recently built condos in the most desirable central wards. Buyers there are increasingly paying prices that make sense only if scarcity and capital appreciation continue doing a lot of the work.
The rest of Tokyo is expensive, but the evidence is much less extreme.
So if someone asks whether Tokyo property is in a bubble right now, our answer is: central Tokyo increasingly yes, Tokyo as a whole not yet.
The next test may settle the debate. Mortgage costs are climbing while affordability is already stretched. If central condo prices keep outrunning rents and household incomes under materially more expensive financing, it will become very difficult to argue that fundamentals alone are driving the market.

OUR METHODOLOGY
This analysis tests whether Tokyo property is in a bubble right now by separating the question into several checks: new-condo pricing, resale pricing, land values, affordability, rents, speculative turnover, foreign demand, mortgage conditions, credit growth, supply, population and market liquidity.
We did not treat one record new-build average as proof of a bubble. New-condo prices were compared with resale transactions and land-price data because Tokyo's shrinking new-build supply and luxury-heavy project mix can move headline averages much faster than the broader housing stock.
Affordability and rental fundamentals were treated as a separate test. We compared the rise in home values with rents and household incomes, then looked at current mortgage rates to judge whether buyers are being asked to support higher valuations with less favorable financing.
Speculative behavior was assessed using the Ministry of Land, Infrastructure, Transport and Tourism's work on short-term resales and overseas-address purchases. We gave more weight to the central-ward results because the strongest price growth, foreign demand and flipping activity are geographically concentrated rather than evenly spread across Tokyo.
We also kept valuation risk separate from systemic financial risk. The Bank of Japan's Financial System Report was used to assess whether rising real-estate lending is creating a broader credit imbalance comparable with Japan's late-1980s bubble, rather than assuming expensive property automatically means a banking crisis.
Supply and underlying demand were used as the main counterweights to the bubble case. New-condominium launches are at a multi-decade low, construction costs are high, Tokyo is still gaining residents and rents are rising, so the market cannot be explained by speculation alone.
Because these datasets are released on different schedules, we used the latest relevant reading available for each part of the analysis instead of forcing every indicator into one reporting month. We also gave less weight to isolated monthly jumps when a changing project mix could plausibly explain them.
Key sources used for this analysis include: the Real Estate Economic Institute's H1 2026 new-condominium report, its 2025 annual new-condominium report, REINS July 2026 resale market data, Tokyo Metropolitan Government's 2026 land-price release, MLIT's study of short-term condo resales and overseas-address purchases, the MLIT Real Estate Information Library, Tokyo's January 2026 resident-register population release, the Statistics Bureau of Japan's migration report, the UBS Global Real Estate Bubble Index, Savills' Tokyo residential leasing research, Japan Housing Finance Agency Flat 35 mortgage rates, and the Bank of Japan Financial System Report.
