How a ¥100-Million Price Tag Made 40-Year-Old Apartments the

With the average Tokyo new condo surpassing ¥100 million, the old “buy new or bust” mindset is rapidly fading. A new survey shows over 80% of renovation-minded buyers now consider used apartments first, as consumers prioritize financial logic and personalised living over the allure of a fresh build.

How a ¥100-Million Price Tag Made 40-Year-Old Apartments the New Hot Property

Tokyo’s new condo market has undergone a decade of relentless price escalation. According to the Real Estate Economic Institute, the average price of a newly built apartment in the capital region jumped from approximately ¥55 million in 2015 to over ¥100 million by 2025, effectively shutting out a large swath of middle-income households. This sticker shock has fundamentally altered how would-be owners approach the property search.

A fresh survey by renovation specialist Renovate Inc. reveals the depth of the shift: more than 80% of its users now consider a used apartment as their first choice, abandoning the once-standard habit of browsing new builds first. The company notes that even five years ago many clients saw new condos as the default option; today the search starts squarely in the secondary market, often with buildings around 40 years old.

Financial frustration with renting is also fueling the trend. The survey found that 57.0% of respondents cited “wasted rent” as a trigger for buying — a figure that has grown roughly 1.4 times since 2021. At the same time, the share who view a home as an asset-building tool nearly doubled, climbing from 13.0% to 24.2%. The message is clear: for a growing cohort, a property is no longer just a place to live but a deliberate move to stop paying a landlord and start accumulating equity.

Why Renovation Is Becoming Tokyo’s Most Popular Housing Strategy

The Price Maths Behind the Pivot

The arithmetic is compelling. Even after factoring in a renovation budget of ¥5–15 million — a realistic range for a full interior overhaul — the total cost of a 40-year-old apartment in a decent location still comes in well below the ¥100 million benchmark for a new unit of comparable size. For households earning roughly the average Tokyo income, the trade-off is not about sacrificing quality; it is about whether they want a smaller new apartment in a distant suburb or a larger, personalized space closer to the city centre.

Why Buyers Are Choosing to Pour Money into 40-Year-Old Walls

Beyond pure cost, a cultural shift is at play. The ability to rip out walls, redesign the layout and install modern kitchens and bathrooms means the finished home reflects the owner’s taste, not a developer’s standardized template. Renovation firms report that clients are increasingly motivated by the chance to craft an “ideal home” rather than simply accepting a compromise. This dovetails with the growing asset-formation mindset: a well-renovated apartment in an established neighborhood can hold its value and may even appreciate relative to the aging new-build that depreciates the moment its keys are handed over.

The Risks Hidden in a 40-Year-Old Building

The strategy is not without pitfalls. Apartments built before the 1981 revision of Japan’s seismic standards may require costly reinforcement. Long-term repair plans, reserve fund balances and the health of the owners’ association are critical — ignoring them can mean sudden, five- or six-figure special assessments for large-scale works. Lenders are increasingly offering renovation-inclusive mortgage products, but the appraised value of older properties can sometimes limit the total loan, requiring a larger down payment than a comparable new purchase. Buyers who skip a thorough building inspection risk nasty surprises that can wipe out the entire renovation budget.

What You Must Know Before Buying a 40-Year-Old Apartment to Renovate

For households seriously considering a 40-year-old apartment as their next home, a disciplined pre-purchase routine can turn the risks into a manageable checklist.

Verify the building’s structural standards. Confirm whether the apartment meets the 1981 “new seismic code” (shintaishin) or has undergone reinforcement. If not, budget an engineering assessment and potential upgrade costs.
Request the long-term repair plan and reserve fund balance. A fund that is under one-third of the projected 30-year needs is a red flag. Ask for the last general meeting minutes to gauge whether special levies are on the horizon.
Calculate the all-in cost. Add the purchase price plus a renovation estimate of ¥5–15 million (based on floor area and desired scope), agent fees and acquisition taxes. Then divide by the net floor area and compare the result with the per-square-metre prices of new units in the same ward. A cost per square metre below ¥1.2–1.4 million is a strong signal of value.
Check the finance package. Some lenders now offer “purchase plus renovation” loans that release renovation funds in phases. Confirm what appraisal value the bank will assign — a low appraisal can force a larger down payment.
Review the building’s management rules. Many older buildings restrict plumbing or wall relocations. Your renovation plan is worthless if the owners’ association vetoes it.
Factor in the rent you won’t pay. The survey’s 57% “wasted rent” motivation is more than emotion. Estimate how many years of ownership — including mortgage interest, maintenance fees and renovation amortization — it will take to beat the cost of renting an equivalent apartment. For a ¥60 million total investment, beating a ¥200,000 monthly rent often takes less than a decade.
