Tokyo Condo Prices Reach Record as Japan Weighs Limits on Speculation

A 94.89 million yen home and fewer ways to cool prices

The average price of a newly built condominium in the Tokyo metropolitan area reached 94.89 million yen between April and September 2025, up 19.3 percent from the same period a year earlier, according to the Real Estate Economic Institute. The record comes as the number of new homes entering the market has almost halved over a decade, leaving local households competing with investors for a shrinking pool of properties.

Developers brought about 45,000 new units to market across the metropolitan area in 2014, compared with around 23,000 in 2024. Those figures represent a decline of roughly 49 percent. Rising construction and land costs, redevelopment delays and limited capacity in the building trades have made it harder to replace the lost supply.

Prime Minister Sanae Takaichi has instructed the Ministry of Land, Infrastructure, Transport and Tourism, known as MLIT, to establish how many condominiums foreign nationals are buying and publish the findings quickly. Since spring, the ministry has been examining property registries to track buyers' nationality and location. As of December 16, 2025, publication remains the next milestone, with no release date given.

Foreign demand has become a focus of public debate, partly because a weak yen makes Japanese property cheaper for people buying with stronger currencies. Preliminary government findings nevertheless suggest that foreign purchasers account for a modest share of transactions. A recent survey found that about 3 percent of buyers of new property in Tokyo had overseas addresses.

Japan's commitments under the World Trade Organization complicate proposals to restrict purchases according to nationality. Developers have already begun targeting rapid resales through contract penalties, while policy discussion is turning toward taxes, better reporting, enforcement of housing rules and more construction. The central problem is broader than the identity of buyers: demand continues to exceed the supply of new homes.

Why fewer homes and a weak yen matter

Tokyo's shortage of new condominiums means each development can attract more competing buyers. When fewer homes are offered for sale, purchasers have fewer alternatives, and developers have more room to raise prices. Redevelopment delays, expensive land and construction, and limited building capacity all restrict how quickly another project can reach the market.

The yen's decline has added demand from purchasers holding dollars, euros or other stronger currencies. A buyer converting dollars into yen can receive more yen for the same dollar budget when the Japanese currency weakens. A 10 percent currency movement can therefore offset much of an increase in a property's price in yen.

Investors also view Tokyo as a relatively safe market amid uncertainty elsewhere. Stable political conditions, a deep mortgage market and strong rental demand in central wards contribute to that appeal. Buyers looking for rental income and households seeking a home can consequently compete for units in the same developments.

Japanese mortgage rates remain low by global standards. Even as the central bank gradually changes its policy settings, fixed rate loans remain affordable for many households. Lower borrowing costs allow buyers to support higher purchase prices, especially where the number of homes is restricted by zoning, available plots and construction schedules.

Supply, financing and currency movements are working together. Stronger purchasing power does little to ease affordability when there are too few units to buy. The combination helps explain why prices have reached new records even while the government is still measuring the scale of foreign participation.

What the foreign buyer figures show

MLIT's registry review is intended to give policymakers a clearer picture of who is buying and where buyers are based. Early indications point to a smaller foreign share than the public debate often assumes. One person involved in the review said the proportion appeared lower than that debate suggested.

The survey finding that about 3 percent of buyers had overseas addresses measures residence rather than nationality. Foreign nationals who live and work in Japan may have Japanese addresses, so a count of overseas addresses covers a different group from a count of foreign citizens. Both measures help describe demand, but they answer different questions.

A small share of purchases can still influence prices where available supply is thin. Developments near new stations or waterfront redevelopment areas can attract both people intending to live in the homes and investors seeking gains. Competition concentrated in a popular project can affect its prices even when foreign participation across the wider market is modest.

Some purchasers seek to profit by reselling contracts before construction is complete. These transactions can produce higher asking prices for subsequent releases within the same development. Developers' new restrictions therefore focus on rapid resale by any buyer, rather than on nationality.

Government officials have sought to address concern about foreign buying without encouraging hostility toward foreign residents. Their priorities include measuring purchases more accurately, strengthening identification and reporting requirements, and making registry information clearer. Enforcement of housing and lodging rules is also part of the discussion, particularly where homes sold for residential use are illegally converted into short term tourist accommodation.

How Japan's WTO commitments limit restrictions

Japan's legal choices during the creation of the World Trade Organization help explain why a broad restriction on foreign purchases would be difficult. The Uruguay Round negotiations established the WTO and embedded principles including most favored nation treatment and national treatment. Japan adopted a liberal approach to real estate transactions when the WTO era began in 1995, encouraging investment from abroad and avoiding restrictions based on buyers' nationality.

Most favored nation treatment concerns equal treatment among trading partners. National treatment concerns how foreign participants are treated compared with domestic participants in sectors covered by commitments. Where those obligations apply, nationality can be a difficult basis for giving a foreign buyer less favorable access than a Japanese buyer.

Changing Japan's commitments is possible in theory, but would require discussions with trading partners and could bring objections or demands for compensation. Countries whose residents invest in Japanese property could also apply reciprocal pressure. Rewriting the commitments would take time, making this a complicated response to an immediate affordability problem.

The United States and Australia preserved room in their arrangements to distinguish between foreign and domestic buyers in land acquisitions. Japan did not build in comparable limits. Its earlier decision to keep property transactions open now places a higher legal bar in front of proposals to reverse that approach.

Japan has a separate framework for security concerns. A law passed in 2021 allows the government to review and regulate the use of land around critical sites, including Self Defense Forces bases and nuclear facilities. It provides for monitoring and possible intervention where land use raises national security concerns. Its purpose is focused on those locations and activities, rather than the price pressures affecting the wider housing market.

Measures applied equally to all buyers and sellers offer a more practical route within these boundaries. Rules discouraging rapid speculation or increasing the cost of leaving homes vacant can be designed around behavior rather than nationality. Politically, however, such policies also affect Japanese investors and households.

Developers put penalties on rapid resales

Major developers have moved ahead with tighter sales contracts. One company told prospective buyers at a large Tokyo waterfront development that reselling a unit before handover would result in the loss of the deposit and termination of the contract. Another introduced a ban on resale for five years at multiple Tokyo projects, with a penalty equal to 20 percent of the property price for violations.

Both approaches apply to purchasers regardless of nationality or residence. Their target is flipping, the practice of buying mainly to sell again quickly at a higher price. A restriction before handover addresses the period when a buyer may try to trade a purchase contract before receiving the completed home.

Rapid resales can create new comparable prices, meaning prices used as reference points when valuing similar properties. If a contract changes hands at a steep markup, that transaction can influence what later buyers are asked to pay. Developers hope that reducing the incentive to flip will keep more units with people who intend to use them and bring greater price stability within a project.

These provisions could become a common feature of popular launches in central wards if more developers adopt them. For purchasers, the practical consequence is that the freedom to resell may be restricted for a substantial period, and breaching the contract can carry a large financial cost.

Developers also have other ways to favor buyers likely to live in the property. Lotteries, declarations of intended occupancy, limits on multiple purchases under the same name and closer checks on financing can make it harder to accumulate homes purely for trading. Companies must balance fair access and careful verification with the presales that help fund construction, while avoiding discrimination based on nationality.

Taxes and vacant homes enter the policy debate

Japan already taxes individuals' gains on property held for shorter periods at higher rates. Policymakers could consider stronger rules for quick resales, including transactions involving contracts before handover, or extend the period during which higher rates apply. The aim would be to reduce the reward from buying and selling rapidly.

Any such change would need to account for people forced to sell because of genuine changes in their lives. A rule aimed at speculation can also affect an ordinary household that needs to move. The question is how to discourage trading without imposing the same burden on every urgent sale.

A vacancy tax would address a different behavior: keeping a home unoccupied. Several cities around the world use such taxes to encourage owners to rent out or sell empty properties. A Japanese measure applying to all owners, irrespective of nationality, could raise the cost of leaving units unused while households struggle to find housing.

Exemptions for renovation or documented hardship could make a vacancy policy fairer. Higher holding costs would be intended to bring existing homes back into use, while resale taxes would target the incentive to trade. Both are options under discussion, alongside measures to improve supply and access for residents.

More construction and better access for households

Tokyo's drop from about 45,000 new units in 2014 to around 23,000 in 2024 puts construction at the center of the affordability debate. Reducing speculative demand may ease pressure, but a larger pipeline of homes would give purchasers more choice and reduce competition for each release.

Possible measures include faster approval for converting underused offices into housing, modest increases in permitted floor area in places well served by transport, and infrastructure that supports greater density. A floor area ratio determines how much building space can be constructed relative to the size of a plot. Allowing more space can make room for additional homes where other conditions permit.

Targeted subsidies could encourage housing in the middle of the market rather than concentrating new construction in luxury towers. These options would take time to produce units, especially where land availability, construction schedules and building capacity already constrain development.

Assistance for people buying their first home could include help with down payments, lower closing costs or mortgage guarantees for households below specified income thresholds. Such measures could help residents compete, but broad support for borrowing also increases purchasing power. If the number of homes stays fixed, that extra demand can push prices higher.

Standardized reporting at the completion of a sale could record buyers' nationality or residence status, with results published in aggregated, anonymous form. Stronger rules identifying the people who ultimately own property through companies or other arrangements could also reduce the use of opaque ownership structures.

Enforcing existing housing rules offers another practical measure. Preventing illegal short term lodging in residential units protects neighbors and helps preserve homes for residents. Together, construction, targeted assistance, transparency and enforcement address different parts of the same shortage.

Why overseas restrictions are difficult to copy

Canada introduced a temporary ban on foreign home purchases in 2023 and later extended it. Singapore imposes additional buyer stamp duty at much higher levels for nonresidents than for citizens and permanent residents. These policies directly change the conditions under which foreign purchasers enter the market.

Australia directs most foreign purchases toward new construction and uses strict enforcement against illegal acquisitions of existing homes. New Zealand restricted most purchases of existing homes by nonresidents in 2018, with certain exceptions based on treaties.

Each approach reflects the country's own laws and trade commitments. Japan's WTO era arrangements left less room for different treatment of domestic and foreign purchasers, while openness to investment has been part of Tokyo's appeal. Adopting comparable restrictions would therefore involve a complex and contentious legal change.

Japan's more accessible options focus on changing incentives for everyone and removing barriers to construction. That approach shifts the debate from the nationality of a purchaser to whether a transaction adds speculative pressure, leaves a home unused or helps meet demand for places to live.

What officials and an economist say

The land minister has pledged to work with other agencies on problems surrounding condominium transactions while supporting social cohesion. Ministers have stressed the need to establish the facts and keep policy within legal limits. MLIT's registry review is central to that effort.

Osamu Tanaka, executive chief economist at the Dai ichi Life Research Institute, has called for a broad response to the forces pushing prices higher. He said:

Even if the percentage of real estate acquired by foreign nationals is small, it could still have the impact of pushing up prices. Since there is no single cause, a comprehensive approach is required.

His assessment brings together the two main strands of the debate: even a modest group of buyers can affect a market with limited supply, while affordability depends on more than that group's purchases. Currency movements, financing costs, construction constraints and speculative resale all shape the prices households face.

The current strategy combines better data, enforcement of existing rules, restrictions on behavior that inflates prices and efforts to increase supply. None promises an immediate fall in average prices. Together, they could ease pressure and improve access for households that live and work in Tokyo.

What buyers face and what comes next

People seeking a home to live in face more competition for fewer units, alongside stricter contract conditions. Buyers should expect closer verification and provisions limiting the transfer of contracts before handover. A plan to move or sell needs to take account of the restrictions attached to the particular development.

Investors seeking a quick return face greater risks as developers expand penalties and proposals to tax shorter holding periods attract attention. Sellers and developers still have a deep pool of potential bidders, but their pricing power is receiving closer public and regulatory scrutiny.

Japan's policy debate has unfolded over several stages:

• In 1995, Japan entered the WTO era with an open approach to real estate transactions.
• Between 2014 and 2024, annual new condominium supply in the Tokyo metropolitan area fell from about 45,000 units to around 23,000.
• In 2021, Japan passed legislation governing land use around critical security sites.
• Since spring 2025, MLIT has been examining property registries to track buyers' nationality and location.
• Between April and September 2025, average new condominium prices reached 94.89 million yen, a rise of 19.3 percent from a year earlier.

MLIT's publication will help ground decisions about foreign participation in transaction data. The larger task is rebuilding a sustainable supply of housing in a city that continues to attract jobs and students. Japan retains tools to discourage speculation, put existing homes to better use and expand construction within its trade commitments.
