New vs. Used Property in Japan
New vs used property in Japan comes down to how much you value a warranty and a blank slate against price, location, and floor area.12 New construction (新築 (shinchiku, "newly built")) carries a documented price premium and a statutory 10-year structural warranty, while used property (中古 (chuko, "secondhand")) buys more space in more central neighborhoods for the same budget, plus a management history you can inspect before committing.32
Procedures, fees, and requirements can change. Confirm current details at Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT).
Overview
This guide compares buying new against buying used for prospective owner-occupiers in Japan. It covers the premium, the legal protections on new builds, the used-property case, and inspection practice, then closes with a decision framework by buyer goal.
The comparison itself applies nationwide and to buyers of any nationality. Prices and stock dynamics vary sharply by metropolitan area, so treat every figure below as a range anchored to its source and date, not a national fixed price.1
The New-Build Premium: What the Extra Money Buys
New construction costs more than equivalent used property in a way that has no close parallel in US or UK markets. Japanese buyers hold a strong cultural preference for new homes, and that preference sustains the premium even where the building itself is comparable.1
How large the premium runs
The working range for this guide is a premium of typically 10 to 25 percent above an equivalent used property (as of 2026-09; confirm current figures with MLIT transaction price data).3 Tokyo-specific investor analysis puts the central-Tokyo condo premium higher, at 20 to 40 percent over comparable resale units, with new per-sqm medians near 1,500,000 yen against about 1,110,000 yen for 10-year-old stock (as of 2026-04).3
A second advisory source states new homes cost approximately 45 percent more than comparable used homes in the same area, citing the Japan Housing Finance Agency Flat 35 borrower survey for FY2024 (as of 2026-07).1 Read the three figures as a ladder: the national working range at the bottom, Tokyo premiums above it, and single-survey highs at the top (limitation: the 20 to 40 percent and 45 percent figures are secondary analyses, not MLIT headline statistics).
Tokyo 23-ward new condos average over 110M yen while regional markets price far lower, so a Tokyo premium never transfers directly to a regional city (as of 2026-07).1
Appliances, finishes, and energy performance
New homes need little or no extra spending at purchase. There are no wallpaper changes, no appliance updates for the dishwasher, air conditioner, or oven, and no leaky-roof or dated-bathroom repairs waiting on day one.2
New homes are built to the latest disaster-prevention measures, with soundproof and fireproof walls and earthquake-capable frames. Modern condominiums add multi-level security, from building entry through elevator call to unit door.2
Buying early in a large condo project also buys choice. Developers offer many floor plans at varied prices, plus layout, color scheme, countertop, flooring, and appliance customization at low or no cost during construction.2 Some developers additionally offer warranties of up to 10 years against defects in appliances such as dishwashers, air conditioners, and ovens, though these are developer offers, not the statutory warranty described below (limitation: single brokerage claim).2
Legal Protections on New Builds
The new-build warranty is the strongest legal argument for buying new. It is a statutory minimum that applies to every new home regardless of builder, price point, or buyer nationality.4
The governing statute is the 住宅品質確保促進法 (jutaku hinshitsu kakuho sokushin ho, "Housing Quality Assurance Act, Act No. 81 of 1999"). Its Chapter VII, Articles 94 to 97, sets special defect-warranty rules for new-house construction and sale contracts.5
What the 10-year warranty covers
Every seller or builder of a new home must provide a 10-year defect liability period from delivery. It covers structural elements, meaning foundations, pillars, beams, floor slabs, roof panels, and load-bearing walls, and waterproofing, meaning roofs, exterior walls, windows, and drainage pipes.4
The 2009 Housing Defect Warranty Enforcement Law backs the promise with money. Builders must carry defect-liability insurance or lodge a cash deposit, so claims survive even if the builder goes bankrupt.4 Confirm the insurance certificate at closing and file it with the deed.
Major builders add voluntary after-service programs on top of the statute. Initial extended terms run 20 to 30 years depending on the builder, conditional on attending scheduled inspections and paying for recommended maintenance.4
What it does not cover
Interior finishes fall outside the statutory 10-year scope. Wallpaper, flooring, paint, appliances, and most plumbing and electrical systems are handled by shorter builder warranties instead.4
Interior finish warranties typically expire at the 2-year mark. Missing the 2-year inspection can end the right to have those defects repaired under warranty, so put the date in the calendar immediately after closing.4
The Used-Property Case
Used homes tend to be cheaper overall because the structure has depreciated and the safety and disaster-prevention specs are older. The value holds only if renovation costs stay under control.2
Price and floor area for the same budget
Used properties often allow price negotiation, which is rarely possible on new builds.2 The same budget therefore buys more floor area, and in central locations such as downtown Tokyo, used stock offers far more options because new construction concentrates in suburbs where vacant lots remain.2
Used stock is also the main route to traditional Japanese-style homes with sliding doors and tatami, and to established character neighborhoods where no new condominiums have launched for years.2
The discount and negotiation headroom on a used purchase can cover the inspection fee plus first-year fixes. Get the inspection quote before making the offer so the numbers sit inside the negotiation, not on top of it.26
Management history you can actually check
A used condo shows its record before purchase. Buyers can review the current repair reserve and management fee levels, past large-scale repairs, and even the resident atmosphere during viewings, none of which exists for an off-plan new sale.2
Buying Used Safely: Inspection Practice
Home inspection (ホームインスペクション (homu insupekushon, "home inspection, general inspection service")) is slowly becoming standard practice for used purchases, supported by a government framework that dates back over a decade.6 MLIT compiled its existing-house inspection guideline in June 2013 so consumers could grasp a used home's condition at transaction time through third-party inspection.7
Building condition survey and home inspection
Two terms describe the same visit at different levels of formality. A home inspection is the general private-company service for used, new, or renovated homes.6 The building condition survey (建物状況調査 (tatemono jokyo chosa, "building condition survey, MLIT standardized system")) is the ministry's standardized system for existing-home sales, focused on main structural components.6
Inspections are visual and non-invasive. The inspector checks exterior and interior structure, measures tilt with gauges, examines foundations and attics, and notes water, electrical, and pest signs.68 Water supply, drainage, and plumbing equipment are usually excluded unless added as options.8
Inspectors are typically licensed architects or MLIT-certified inspectors.68 Since the April 2018 Real Estate Brokerage Act revision, agents handling used-home sales must explain the inspection system, disclose whether a survey was done, and arrange one if requested.68 Every used-home contract must state whether an inspection took place.
Inspection is never mandatory for a transaction. It proceeds only with the seller's consent.68
The standard flow looks like this:
Cost, timing, and consent
| Item | Amount | As of | Notes |
|---|---|---|---|
| Detached-house basic visual inspection | 50,000–70,000 yen | 2026-07 | Detailed reports beyond visual can double the price6 |
| Condo basic visual inspection | 40,000–60,000 yen | 2026-07 | Size, location, and age move the price6 |
| Market price cited by second source | around 50,000–60,000 yen | 2018-03 | Paid by the requesting party; varies by contractor8 |
Figures above are 2026 and 2018 source values respectively; confirm current fees with the inspection company before budgeting (as of 2026-07; confirm current figures with the inspection company). Most inspection companies operate in Japanese only, and reports are typically Japanese as well, so line up a bilingual agent or translator before relying on the report.6
The buyer normally bears the inspection cost, and scheduling plus reporting takes time. During that wait the seller may accept a competing offer, so discuss timing with the agent early enough that the inspection does not cost the property itself.6
Choosing Between New and Used
No option wins outright; the right choice follows the buyer's goal. The flowchart below maps the two most common profiles.
When new fits better
New fits buyers who want minimal early repair spending, the latest earthquake and fire specs, and easier mortgage arrangement through developer banking relationships.2 Developer-linked financing is typically easier to secure and on better terms because the property has no depreciation history and the developer stands behind defects.2
When used fits better
Used fits buyers prioritizing lower entry price, central locations, larger floor area for the budget, and room to negotiate.2 Inspection results then set the repair budget, and where criteria are met, buyers can access building-defects insurance for used-home transactions.8
Good to know
The 1981 earthquake standard line still matters for older used stock
Homes designed before June 1, 1981 were built to an older earthquake-resistance standard. A full seismic retrofit for a typical wooden house can cost 1,000,000 to 3,000,000 yen, so check the building's construction confirmation date before committing.6 Most banks finance post-1981 buildings while pre-1981 stock faces restricted or unavailable mortgage financing, which further discounts its resale value.3
Used does not automatically mean renovation-ready
Homes built before 2006, when asbestos was fully banned in building materials, may need an asbestos survey. Renovation work over 1,000,000 yen or demolition over 80 sqm legally requires one regardless of whether asbestos is suspected.6
Termite damage deserves a close check in older wooden houses. It affects structural elements directly and leads to costly repairs down the line, so flag it specifically with the inspector rather than assuming the standard visual pass covers it.6
