New Detached Houses in the Tokyo Metropolitan Area Average 53.67 Million Yen. Loans for Most, but the 23 Wards Require Significant Personal Funds
New detached houses for sale in the Tokyo metropolitan area have become quite expensive.
According to Recruit's "2025 Tokyo Metropolitan Area New Detached House Buyer Trend Survey", the average purchase price in 2025 was 53.67 million yen. This is an increase of 5.23 million yen from 2024, reaching the highest level since the survey began in 2014. The survey covered 612 contracts for new detached houses in the Tokyo metropolitan area from January to December 2025.
Looking at this alone, one might think, "Have detached houses become assets just like apartments?"
However, looking closer at the survey, it's not that simple.
People buying new detached houses seem to be absorbing price increases through loans and dual incomes to make family life work, rather than chasing asset value.
Prices at Record Highs. Tokyo's 23 Wards Exceed 80 Million Yen
First, the price.
The average purchase price for a new detached house in the Tokyo metropolitan area in 2025 was 53.67 million yen. It rose by 5.23 million yen in one year from 48.44 million yen the previous year.
In Tokyo's 23 wards alone, the average was 82.87 million yen, exceeding 80 million yen for the first time since the survey began. In the 23 wards, "60 million yen or more" accounted for 77.1%, suggesting it should be viewed as a different market from the rest of the metropolitan area.
Meanwhile, Saitama and Chiba prefectures are in the 38 million yen range, showing a significant gap within the metropolitan area.
In other words, even for new detached houses in the Tokyo metropolitan area, the price perception differs greatly between the 23 wards and the surrounding prefectures.
Buyers are High-Income Dual-Earner Households
As prices rise, the demographic that can afford them naturally changes.
The average total annual household income of contracting households was 9.38 million yen, also the highest since the survey began in 2014. Households with 10 million yen or more increased from 26.0% in 2024 to 34.0% in 2025.
In Tokyo's 23 wards, the average total annual household income was 13.01 million yen, with 65.3% of households earning 10 million yen or more.
Furthermore, the ratio of dual-earner households is also rising. The dual-earner ratio for all contractors was 72.2%, and 75.8% for married households. For "couple-only" households, it exceeded 90% for the first time at 93.2%.
What we see here is that new detached houses are no longer "homes bought by standard single-earner households."
To buy a new detached house in the current Tokyo metropolitan area, both spouses work to build up household income, and any shortfall is covered by a loan.
This has become the structure.
Full Loans are Increasing Overall. But the 23 Wards Require Thick Personal Funds
However, an increase in high-income households doesn't necessarily mean they have plenty of personal funds.
The percentage of "0 yen personal funds," or so-called full loans, was 32.8%. This is also the highest since the survey began in 2014. Average personal funds were 7.13 million yen, down 160,000 yen from 2024.
The total loan amount is also increasing. The average total loan amount for borrowers was 48.42 million yen, the highest since the survey began. Loans of 50 million yen or more accounted for 38.4%.
However, the scenery is a bit different in Tokyo's 23 wards.
In the 23 wards, 11.0% of people put in "20 to less than 30 million yen" of personal funds. Furthermore, "30 million yen or more" accounted for 8.5%. Combined, 19.5% of people purchased with 20 million yen or more in personal funds.
The average personal funds in the 23 wards were 9.94 million yen, compared to the overall average of 7.13 million yen. It can be read that in the 23 wards, it's a price range that's hard to reach without adding substantial personal funds, rather than just pushing through with a loan.
Moreover, loans in the 23 wards are also large. The average total loan amount for borrowers was 68.22 million yen, with 82.4% of loans being 50 million yen or more.
Overall, it's a "market reached by loans."
In the 23 wards, it's a "market where thick personal funds are added to large loans."
Even for the same new detached house, the content of the financial plan is quite different. High income and dual earnings seem to be conditions for keeping up with rising housing prices rather than signs of affluence.
The Reason for Buying is "Family" Rather Than Asset Value
This is a characteristic of detached houses.
The most common reason for purchasing a new detached house was "Because I wanted to own a home for my children and family" at 59.0%. Next was "Because I wanted to live in a larger house" at 43.5%. On the other hand, "Because I wanted to own an asset or thought it was advantageous as an asset" remained at 15.7%.
According to Recruit's explanation, unlike apartments, detached houses are centered on the reason of "wanting a home for children and family" rather than asset value.
In other words, just because new detached houses in the Tokyo metropolitan area are becoming expensive doesn't necessarily mean they are becoming investment products.
Rather, to secure the space necessary for the family, people are stacking income through dual earnings, increasing loans, and in some areas, putting in thick personal funds.
I think this view is closer to reality.
*As a reference, for new apartments, "Because I wanted to own an asset or thought it was advantageous as an asset" was the highest at 36.7%.
Price Over Proximity to Station. Building Over Land
So, what do buyers prioritize?
The most prioritized item when considering a purchase was "Price" at 88.9%. This was followed by "Size of the residence" at 55.4%, "Time from the nearest station" at 54.2%, "Number of rooms" at 54.1%, and "Floor plan" at 53.9%.
In Tokyo's 23 wards, "Price" was 91.5%, "Size of the residence" 64.4%, "Time from the nearest station" 61.0%, and "Number of rooms" and "Floor plan" both at 65.3%.
On the other hand, "Time from the nearest station," "Sunlight," and "Area with good commuting access" decreased slightly from 2024, reaching the lowest values since the survey began in 2014.
This likely means that it's not that they stopped caring about station proximity or sunlight, but that they can no longer have it all.
As prices rise, it's difficult to satisfy station proximity, size, land, sunlight, and commuting convenience all at once. As a result, they look at the price first, then the size and floor plan of the building, and adjust for station distance and sunlight.
The way of choosing is changing in that way.
In fact, the building area has not collapsed much. The average building area was 98.6 sqm, almost the same as in 2024. Meanwhile, the average land area was 115.0 sqm, shrinking by 3.5 sqm from 2024.
Buyers protect the size of the building as much as possible.
Instead, they compromise on land area, station distance, and location conditions.
If the reason for buying a detached house is "for the family" and "for space," this movement is natural.
Used Detached Houses Have Also Become Realistic Comparison Targets
Another thing to note is the parallel consideration of used detached houses.
Among housing types considered other than new detached houses, "Used detached houses" was the highest at 41.3%. This rose from 36.7% in 2024, reaching the highest level since the survey began in 2014.
This is quite important.
Even people who bought new detached houses didn't only look at new ones from the start.
As prices rise, used detached houses are being seen as a realistic option.
It's not about new or used, but about where and at what price the space necessary for the family can be secured.
The axis of comparison has shifted there.
New Detached Houses are Homes for Actual Demand. However, the 23 Wards Have Become a Market for a Limited Group
New detached houses are bought as homes for actual demand to support family life, rather than as products chasing asset value.
However, that doesn't mean they are "within everyone's reach."
Especially in Tokyo's 23 wards, the average purchase price is 82.87 million yen, average household income 13.01 million yen, average personal funds 9.94 million yen, and average total loan amount 68.22 million yen. 19.5% of people put in 20 million yen or more in personal funds.
Overall, it's a "market reached by loans." In Tokyo's 23 wards, it's a "market where thick personal funds are added to large loans."
Even for the same new detached house, the conditions for those who can buy differ greatly between the 23 wards and elsewhere.
