To maintain an "ordinary life" in Tokyo, allocating 40% of one’s income to rent is becoming increasingly normal. The long-standing real estate rule of thumb that "rent should stay within 33% of income" no longer matches the reality of Tokyo. Even at an annual income level of 7 to 8 million yen, which is socially considered more than comfortable, more people in the industry are saying that they are "just getting by" while paying monthly rent of 160,000 to 170,000 yen. In this article, we analyze the structural reasons behind the sharp shift in the rent-to-income ratio in Tokyo and consider what it means for rental owners and real estate investors.
Key points of this article - Tokyo’s rent-to-income ratio has shifted in practice from the former "33%" benchmark to a "40%" reality - Even with an annual income of 8 million yen, monthly rent in the 170,000-yen range has become "normal," and household financial flexibility is fading - A sharp decline in new housing supply caused by rising construction costs is concentrating demand on existing properties and accelerating rent increases - There is roughly a 1.7 to 1.8 times gap between asking rents and contracted rents, making the market more complex than the numbers suggest - This is a tailwind for rental owners, but if rents exceed levels tenants can live with, there is a risk of damaging the market
Why the "33% of income" benchmark has broken down
For many years, the real estate industry relied on the rule of thumb that "rent should be kept within 30% to 33% of take-home income." This concept is similar to the debt repayment ratio used in housing loans, and it has also influenced tenant screening standards at financial institutions. Behind this benchmark was the idea that households should retain enough room to cover other living costs such as food, utilities, transportation, medical expenses, and child-rearing costs.
Today, however, that premise is being shaken at its foundation, particularly in central areas around Tokyo’s 23 wards. Looking at the actual situation, more cases are emerging in which around 40% has become the "standard" rent-to-income ratio in Tokyo, and the number of households accepting that reality as unavoidable continues to rise.
Why has this happened? There is no single cause. It is the result of three forces moving at once: supply, demand, and cost structure.
The reality of "just getting by" even on 8 million yen a year
An annual income of 7 to 8 million yen is well above the national average. Even so, among working people in their 30s and 40s in Tokyo, it is increasingly common to hear that "this does not mean we are living comfortably." On a monthly basis, that translates to roughly 450,000 to 550,000 yen in take-home pay. If 160,000 to 170,000 yen of that goes to rent, only around 300,000 yen remains.
Once food, utilities, communications, insurance, and transportation are deducted, very little is left for savings. Households raising children also face education costs. Within a standard pattern of spending in Tokyo, households spending 40% of income on rent are likely feeling significant constraints in how they plan their daily lives.
The relationship between commute-required locations in Tokyo and rent levels
For salaried workers in Tokyo, keeping rent down while meeting the condition of living within one hour of the workplace generally means moving to the outer edges of the 23 wards or along major rail lines in Kanagawa, Saitama, or Chiba. That choice is possible when only one partner commutes into Tokyo. But when both spouses work and commute to different offices in central Tokyo, the option of living farther out in the suburbs almost disappears.
As discussed in The relationship between rental housing and satellite offices: changes in work styles and housing choices, shifts in working styles directly affect how people choose where to live. The spread of remote work temporarily encouraged moves to the suburbs, but as the return to office has progressed, demand for areas near central Tokyo has strengthened again.
The "near-central Tokyo wall" facing dual-income households
For dual-income households, if they want to satisfy the condition that "at least one partner can reach work within 30 minutes by train," their residential options are limited to areas within a certain distance of major terminals such as Shibuya, Shinjuku, Shinagawa, and Tokyo Station. By 2026, properties with two bedrooms or more that meet this condition are generally priced above 200,000 yen per month. Even with a combined household income of 12 million yen, rent can easily exceed 20% to 25% of income, and many families still feel that they are by no means living with ample room to spare.
Why have rents risen this much? Three structural factors
Tokyo’s surge in rents is the result of three overlapping structural changes.
First, a sharp decline in new supply. As construction costs continue to rise, the cost of building new apartment projects has increased significantly over the past five years. Order prices paid to construction companies have climbed, and more developers are postponing projects because the numbers no longer work. The supply of newly built rental apartments, especially in urban areas, has fallen noticeably, leaving the market with fewer new options.
Second, demand has concentrated on existing properties. When fewer new properties are built, applicants converge on existing older and relatively new properties. That creates competition, with multiple applications for the same unit, and landlords no longer need to respond to rent-reduction negotiations simply because an application has arrived. In some cases, it has become realistic to say, "We will go with the next applicant."
Third, rent revisions at renewal. In the past, the conventional wisdom in the rental industry was that "rents cannot easily be raised." Today, however, more cases involve rent revisions at the time of contract renewal every two years, based on comparisons with surrounding market levels. Within the industry, people on the ground are now saying things like, "A 10% increase over two years is normal, and compared with nearby market levels, there have even been cases of 20% increases."
Owners who are struggling with property management or rent-setting may also find value in The power of networks to reduce major repair costs by 30%.
The "gap" between asking rent and contracted rent: do not be misled by listed prices
There are indications that in the Tokyo market, the "asking rent" shown on real estate portals and the "contracted rent" actually agreed upon can differ by roughly 1.7 to 1.8 times.
What does that mean in practice? A property that was actually leased for "120,000 yen" may still be listed on a portal at "210,000 yen" — and a certain number of such discrepancies exist. This gap can arise when landlords or agents adopt a listing strategy of "putting it out at a higher price first and negotiating if inquiries come in," and it can also arise when properties remain vacant for long periods because they are priced far above the local market. These different situations coexist in the data.
Across the market as a whole, the average listed rent on portals tends to look higher than the reality, and taking those numbers at face value can lead to flawed income simulations and poor investment decisions. When setting rents, owners should refer not to asking rents on portals, but to contracted-rent data.
From "above 300,000 yen will not lease" to "even 500,000 yen closes"
One of the clearest signs of how much Tokyo’s rental market has changed in recent years is the shift in lease activity in the high-rent segment. In the past, the industry’s instinct was that "rentals above 300,000 yen per month are hard to close." It was a price band seen only in specialized markets serving foreign expatriates and a limited segment of affluent households.
Today, however, properties in the 400,000 to 500,000 yen range are also closing. This is not only a story about a narrow affluent segment. It reflects stronger demand for high-quality properties in prime central locations. The expansion of foreign companies into Japan, the increase in foreign executives, and the rise of tech startups have all added depth to demand from households able to support higher rent levels.
More closings in the high-rent segment raise the market’s overall ceiling. If 500,000 yen properties are leasing, then 200,000 yen starts to feel "still affordable," and the market’s overall sense of price level shifts upward.
How should rental owners read this phase of the market?
For owners, today’s Tokyo rental market is a favorable phase. Demand exceeds supply, and even when a vacancy appears, units are being filled relatively quickly in many cases. Rent revision negotiations have also become easier.
That said, at INA&Associates, we would be cautious about describing this phase unreservedly as a "good opportunity that favors owners." The reason is that a market in which rents continue to rise carries, in the end, the risk that "there will no longer be enough people who can afford to rent."
As we explain in detail in Five strategies to optimize real estate management costs, stable rental management over the long term requires both an appropriate vacancy rate and ongoing relationships with trustworthy tenants. If rent is raised too aggressively, leading strong tenants to move out and the quality of new tenants to decline, that negative cycle can cause more damage than the short-term increase in income is worth.
Precisely because the market is favorable now, this is the right time to invest in a strategic review of rent-setting and in improving tenant satisfaction. Owners considering a rent review are welcome to consult INA’s rental management team. We support appropriate rent-setting based on local contracted-rent data.
INA&Associates’ view: the concern of "whether people can live somewhere at all"
Within the industry, people increasingly voice the concern that "if rents keep rising at this pace, will there soon be no one left who can live an ordinary life in Tokyo?" This is not simply an emotional reaction. It is an economically rational question.
If rent levels above 40% of income become entrenched, lower- and middle-income households will be pushed from Tokyo to the suburbs, and from the suburbs even farther away. This phenomenon is known as "gentrification," and it is a challenge that international cities such as New York, London, and Singapore have already experienced. In Manhattan, this problem intensified from the 2000s through the 2020s, accelerating the outflow of lower- and middle-income households from the city. Urban diversity is eroded, and the city then faces a shortage of the talent needed to support services, manufacturing, logistics, and other essential sectors.
When I consider the sustainable growth of Tokyo as a city, I believe it is necessary not to leave rent inflation untouched as a simple matter of "market forces," but to examine structural improvements on the supply side at the policy level — encouraging new supply, revitalizing the circulation of existing housing stock, and strengthening public rental housing. A cooperative stance among owners, investors, government, and residents in addressing this issue will help preserve a healthy real estate market over the long term.
Conclusion
Tokyo’s rent-to-income ratio is shifting from the industry’s long-held norm of "33% or less" to a new reality in which "40% is normal." Behind that shift are three structural factors: the sharp decline in new supply, concentrated demand on existing properties, and rent revisions at two-year renewal cycles.
- Even among households earning 7 to 8 million yen annually, more are paying around 170,000 yen per month in rent and still only "getting by"
- There is a 1.7 to 1.8 times gap between asking rent and contracted rent, and the market is more complex than surface-level numbers suggest
- Closings in the high-rent segment (400,000 to 500,000 yen) are increasing, raising the market’s overall "ceiling"
- This is a tailwind for rental owners, but rent increases beyond what tenants can sustain undermine the market’s long-term viability
- For long-term stability in rental management, strategic rent-setting matters more than simply following the market upward

Frequently Asked Questions (FAQ)
Q1. Ideally, what percentage of income should rent be kept within in Tokyo?
A. Ideally, rent should stay within 30% to 35% of take-home income, but in today’s Tokyo, 40% is a realistic upper limit. That is roughly the line at which a minimum living standard can still be maintained. To preserve savings, retirement funds, and education budgets, keeping rent at 35% or less whenever possible is advisable. Considering suburban or out-of-Tokyo locations can broaden your options.
Q2. If rent is raised at lease renewal, can tenants negotiate?
A. Legally, rent revisions at renewal require agreement from both parties, and unilateral increases are not permitted. Under Japan’s landlord-tenant law, tenants can generally renew at the current rent unless there is justified cause and they agree otherwise. That said, if there is a significant discrepancy from surrounding market levels, some owners may file a rent increase claim. For any specific negotiation, consulting a real estate professional is advisable.
Q3. Why is the supply of newly built rental apartments declining?
A. The main reason is rising construction costs. In addition to higher material prices for steel, concrete, and other inputs, labor costs continue to rise because of worker shortages in the construction industry, pushing profitability thresholds for new projects much higher. Persistently elevated land prices are also increasing development costs, and more projects are being postponed because they no longer meet return requirements.
Q4. As a rental owner, how should I think about rent-setting going forward?
A. Even in a favorable market, sharp rent hikes can increase the risk of tenant turnover and, over the long term, raise vacancy costs and restoration costs. An effective approach is to understand appropriate market levels using contracted-rent data and make gradual adjustments while maintaining good relationships with existing tenants. INA&Associates provides local rent market analysis based on contracted-rent data, and we welcome your consultation.
