Who are the people mainly engaging in speculative buying and selling?

In major global cities where Chinese investors engaged in large-scale “buying sprees,” residential property prices in some cases doubled or even tripled. In response to surging foreign investment, several governments introduced higher property acquisition taxes and ongoing ownership taxes specifically targeting foreign buyers in order to cool housing demand. However, despite these regulatory measures, real estate prices did not experience any significant long-term decline.

For property owners — including domestic homeowners and investors — rapid property price appreciation quickly becomes a vested financial interest. Rising housing values create strong economic and political resistance to price corrections. That is why policymakers must anticipate future real estate market risks in advance. Once a housing bubble has fully formed, implementing corrective measures becomes far more difficult and potentially destabilizing.

Will Chinese real estate purchases not decrease?

Amid heightened Japan–China geopolitical tensions, the Chinese government has urged its citizens to refrain from traveling to Japan. While a decline in short-term tourists staying fewer than 90 days is expected under these conditions, the more important question for the Japanese real estate market is whether Chinese nationals seeking long-term residency will slow down their move to Japan.

At present, any prediction that Chinese property purchases in Japan will decline significantly remains speculative. A large proportion of Chinese nationals acquiring real estate in Japan already hold mid- to long-term residence status. For many buyers, the motivation extends beyond simple investment returns. A primary driver is asset diversification and wealth preservation outside China, rather than holding assets solely in renminbi.

For some Chinese nationals, overseas property acquisition is effectively part of a broader immigration and capital protection strategy. In many cases, this shift in mindset can be traced to several major political and economic developments: the 2018 removal of presidential term limits allowing President Xi Jinping to remain in power indefinitely; the 2020 enactment of the Hong Kong National Security Law, which tightened political controls; and the strict COVID-era lockdowns imposed in cities such as Shanghai and Beijing in 2022.

Historically, the United States has been the preferred destination for Chinese emigrants and investors. However, following policy shifts under President Donald Trump, including changes in U.S.–China relations and immigration enforcement, relocation to the U.S. has become more challenging. As a result, Japan has emerged as an attractive alternative for Chinese investors and high-net-worth individuals seeking residency options.

Under Japan’s immigration framework, depending on visa category and professional qualifications, permanent residency may be obtainable in approximately five years. This status provides long-term stability and functions as a strategic safeguard — effectively an “exit option” should geopolitical or economic conditions deteriorate in China.

According to data from the Immigration Services Agency of Japan, the number of Chinese nationals residing in Japan has been increasing by roughly 50,000 to 60,000 annually in recent years, reaching approximately 900,000 as of June 2025. If this growth trajectory continues, the Chinese resident population in Japan could surpass one million by around 2027.

Notably, a substantial number of Chinese nationals obtain Japan’s “Business Manager” visa, which requires active business operations and capital investment within Japan. As part of this broader investment strategy, Japanese real estate acquisition — including residential properties, investment condominiums, and short-term rental (minpaku) properties — represents a key component of capital allocation.

From a market perspective, Chinese demand for Japanese real estate is therefore closely linked not only to tourism trends, but also to long-term residency, immigration policy, capital outflow dynamics, and global wealth diversification strategies.

Speculative buying and selling is primarily driven by Japanese individuals and Japanese corporations.

Condominiums purchased by foreign nationals as a base for staying in Japan are overwhelmingly concentrated in central Tokyo. Because the primary objective is often asset preservation and long-term wealth protection, registry records show relatively few resale transactions among these buyers.

In contrast, the majority of speculative real estate transactions in Tokyo are driven by Japanese individuals and Japanese corporations whose primary goal is short-term flipping or investment gains. These domestic speculative buyers account for roughly 30% of condominium transactions in Tokyo’s central wards. Chinese buyers, by comparison, represent approximately 10% of total transactions, suggesting that their direct influence on speculative price inflation is relatively limited.

Rapid Price Growth in Central Tokyo Condominiums

When examining the surge in Tokyo condominium prices, the year-on-year increase in average transaction prices for pre-owned condos in the three central wards — Chiyoda Ward, Chuo Ward, and Minato Ward — has reached approximately 25% annually.

At this compounded growth rate, property values could theoretically double in just three years and triple within five years — an exceptionally rapid pace for a mature real estate market. Even during past periods of aggressive monetary easing, Tokyo property prices did not double over an entire decade. This comparison highlights just how extraordinary the most recent 12-month surge has been.

Government and Industry Response to Speculative Activity

In response to rising concerns over housing affordability and real estate speculation, Chiyoda Ward formally requested action from the Real Estate Companies Association of Japan, an industry body whose members include major developers. The ward proposed two key measures:

1. As a general rule, prohibit resale for five years after handover by attaching special contractual clauses.
2. Prohibit a single buyer from purchasing multiple units within the same building under the same name.

The association later announced a policy discouraging resale before property handover. However, the policy lacks binding enforcement power over its member companies. Even if observed, it would only restrict pre-handover resales, meaning owners could still sell immediately after delivery. Compared with a strict five-year resale ban, the policy’s effectiveness remains limited.

Brokerage Incentives and “Dual Agency” Commissions

Certain real estate brokerage firms have also come under scrutiny for facilitating speculative strategies among high-net-worth clients. In some cases, affluent buyers apply for newly built condominium lotteries with the pre-arranged intention of reselling at a premium after acquisition.

For brokers, this model is highly lucrative. Through so-called “dual agency” representation — collecting commissions from both seller and buyer — a ¥200 million property transaction can generate over 3% per side, resulting in approximately ¥12 million (around $80,000+) in total brokerage fees.

Structural Issues in Japan’s Real Estate Market

From a developer’s standpoint, there is little incentive to accept government-imposed resale restrictions that could slow sales velocity. However, this raises a broader question: if the stated objective is housing stability, why not prioritize sales to end-users who genuinely intend to live in the property?

This tension reflects a deeper structural issue within the Japanese real estate market — the prioritization of short-term revenue and transaction volume over long-term market stability, housing accessibility, and sustainable property price growth.

Ultimately, while foreign buyers — including Chinese investors — often receive public attention, data suggests that domestic speculative activity plays a far larger role in driving central Tokyo’s condominium price surge.

Harumi Flag, a development where no resale restrictions were imposed.

Japan has previously implemented strict resale restrictions to curb condominium speculation and stabilize the housing market — and those policies proved effective.

A prominent example is City Tower Shinagawa, a fixed-term land leasehold condominium developed under an agreement with the Tokyo Metropolitan Government. The project included clear anti-speculation measures:

• Sales prices were pre-arranged in coordination with the government.
• A five-year ban on resale was imposed.
• Leasing was prohibited during the restriction period.
• Units were designated exclusively for owner-occupancy.

As a result, speculative flipping was largely eliminated. Nearly all units complied with the five-year restriction, and the few transfers that occurred were foreclosure auctions rather than voluntary resales. From a real estate policy and housing affordability standpoint, City Tower Shinagawa is often cited as a successful model for limiting short-term speculation in Tokyo’s condominium market.

Harumi Flag and the Absence of Resale Restrictions

In contrast, Harumi Flag — the large-scale redevelopment of the former Tokyo Olympic and Paralympic athletes’ village — did not adopt similarly strict resale controls.

Harumi Flag has drawn significant attention in discussions about Tokyo condominium price inflation and real estate investment speculation. The development land was reportedly sold to private developers at approximately one-tenth of prevailing market value. Under such favorable acquisition terms, the potential for substantial capital gains through resale was foreseeable from the beginning.

Despite this, no comprehensive five-year resale ban or leasing prohibition comparable to City Tower Shinagawa was implemented. This policy difference has become central to debates surrounding:

• Tokyo real estate speculation
• Olympic Village redevelopment strategy
• Government land sales and housing affordability
• Short-term condo flipping in central Tokyo

Criticism of Tokyo’s Housing Policy Approach

Some critics argue that the Tokyo Metropolitan Government’s response to speculative risk at Harumi Flag was insufficient. Others go further, describing it as approaching administrative inaction.

In administrative law, “inaction” refers to a failure by a public authority to fulfill its legal or policy responsibilities. While the legal interpretation remains subject to debate, the policy contrast between City Tower Shinagawa and Harumi Flag highlights broader structural questions about Japan’s housing market governance.

The Bigger Picture: Tokyo Condo Prices and Market Stability

As central Tokyo condominium prices continue to surge, the absence of strong resale restrictions at high-profile developments has intensified public scrutiny. The comparison between City Tower Shinagawa’s strict five-year resale ban and Harumi Flag’s more flexible framework underscores a larger issue:

Should urban housing policy prioritize short-term transaction volume and developer profitability — or long-term market stability and residential affordability?

In the context of rising property prices, foreign investment debates, and growing concern over speculative flipping, the Harumi Flag case remains a key reference point in conversations about Tokyo real estate regulation, condominium resale restrictions, and sustainable housing market policy in Japan.

To provide greater visibility into trends in real estate-related lending.

Property resale is not inherently illegal. However, when rapid flipping and speculative trading begin to distort housing affordability and market stability, the issue becomes a matter of public policy. If the objective is to curb excessive Tokyo real estate price inflation, then policymakers must focus on reducing the flow of capital supported by excessive leverage. In this area, Japan’s Financial Services Agency plays a pivotal regulatory role.

Monitoring Real Estate Lending in Japan

The Financial Services Agency and the Bank of Japan have jointly launched a “Common Data Platform” designed to collect and share highly granular lending data, including detailed corporate loan disclosures. Full-scale implementation began with fiscal year data ending March 2025.

This enhanced financial monitoring system enables regulators to analyze:

• Interest rates on real estate loans
• Loan-to-value (LTV) ratios
• Borrower classifications (individual vs. corporate)
• Maturity structures and refinancing trends

As a result, trends in real estate-related financing in Japan — including aggressive lending that may be fueling short-term condominium flipping — can now be identified with far greater precision.

Identifying Speculative Lending Through Mortgage Data

Speculative properties typically have mortgages registered by financial institutions. By combining property registry data with detailed loan information, regulators can determine:

• Which banks are providing financing
• What lending conditions are being offered
• Whether excessive leverage is supporting short-term resales

This data-driven oversight significantly improves transparency in Japan’s property finance market and makes it easier to detect credit-driven real estate bubbles before systemic risks escalate.

Speculation in Central Tokyo: A Growing Concern

Despite these tools, speculative dynamics continue to emerge in central Tokyo, including areas such as Chuo Ward and Minato Ward. Rapid condominium price increases, high leverage financing, and short-term resale activity closely resemble patterns seen during Japan’s late-1980s asset bubble.

This raises a critical policy question: Why has there been limited visible intervention from local authorities or the Tokyo Metropolitan Government, despite clear signs of speculative activity?

Lessons From Japan’s Asset Bubble

The current environment mirrors many characteristics of Japan’s historic real estate bubble — credit expansion, speculative flipping, and sharp price acceleration in prime urban districts. If the real estate industry and financial institutions fail to internalize the lessons of the past, history may repeat itself.

When highly leveraged speculation unwinds, the consequences can include:

• Developer bankruptcies
• Financial institution losses
• Rapid condominium price corrections
• Broader economic instability

For policymakers focused on Tokyo housing market stability, real estate speculation control, and sustainable property price growth, monitoring credit expansion and leverage remains the most effective early intervention tool.

Ultimately, controlling excessive real estate lending — rather than targeting resale activity alone — may prove to be the most practical strategy for preventing another asset bubble in Japan’s urban property market.
