New Houses for Sale in Japan
Browse 94,000+ brand-new detached houses across Japan, with English listings updated daily.
A 新築一戸建て (shinchiku ikkodate, “new-build detached house”) is a Japanese free-standing home that has never been occupied — built by a developer (dei ripa, デベロッパー) or a local builder (kōmuten, 工務店) and offered for sale before or just after completion. You are buying brand-new construction on a freehold lot, with current seismic code compliance, modern insulation, and the full manufacturer warranties on every system. Unlike the pre-owned market, there is no prior owner, no renovation backlog, and no ambiguity about how the structure was maintained. The trade-off is price: new houses are the most expensive category of Japanese detached housing, and the inventory on this page concentrates in the suburban subdivisions of greater Tokyo, Osaka, and Nagoya where land is still being developed.

What you get with a brand-new Japanese house
A shinchiku ikkodate is the cleanest possible entry into Japanese real estate. Every component — foundation, frame, roof, façade, plumbing, electrical, HVAC, kitchen, bath — is new and under manufacturer warranty. The building meets the post-2000 seismic code (shin-taishin) in full, which means cheaper earthquake insurance and easier financing than any older vintage. Modern Japanese houses also include insulation and double-glazed windows that pre-2000 builds often lack, making them dramatically cheaper to heat and cool. You take possession with no renovation backlog, no surveyor surprises, and a predictable maintenance curve for the first decade.
Developer builds vs. local kōmuten
New detached houses in Japan come from two sources. National and regional developers(deveropa) — Sekisui House, Daiwa House, PanaHome, Misawa — build subdivision tracts of dozens to hundreds of units to a standardized spec, with bundled financing and showroom finishes. A kōmuten (工務店) is a smaller local builder who typically constructs a single custom or semi-custom home on a specific lot, often for an end buyer who already owns the land. Developer spec houses dominate inventory in suburban Tokyo, Osaka, and Nagoya; kōmuten builds are more common in regional cities and on rural lots. The listings on this page mix both, and each detail page identifies the builder where the source portal provides it.
Why new houses carry a premium
Japanese buyers have historically treated houses as depreciating consumer goods rather than appreciating assets, which pushes the newest builds to the top of the price curve. A new detached house in a Tokyo suburb typically costs meaningfully more per square meter than an equivalent-used house on the same block, and land-plus-build packages in central wards can reach the same price band as luxury condos. That premium reflects three things: current seismic-code compliance, full warranties, and the simple fact that the buyer is the first person to live in the structure. Each city page above shows the asking-price spread for new construction in that area, with prices in yen and an indicative USD conversion.
The 10-year defect warranty
The single most important legal protection on a new Japanese house is the mandatory 10-year defect warranty under the Housing Quality Assurance Act(Jūtaku no Hinshitsu Kakuho no Sokushin tō ni Kansuru Hōritsu, 住宅の品質確保の促進等に関する法律, enacted 2000). Under this law every builder — developer or kōmuten — must warrant the structural frame and waterproofing (roof, foundation, exterior) against defects for ten years from handover, by statute, regardless of what the individual sales contract says. Many builders extend separate shorter warranties on fittings, finishes, and equipment. For overseas buyers this baseline warranty is one of the strongest reasons to buy new: it shifts initial structural risk back to the builder for a decade.
Buying as a foreigner
Foreigners can buy and own freehold Japanese real estate outright — no residency, visa, or citizenship required — with title registered at the Legal Affairs Bureau the same way it is for a Japanese national. The process is well-defined: an offer, a bilingual sales contract, payment through a designated bank account, and registration handled by a judicial scrivener (shiho shoshi). Japanese banks rarely lend to non-residents, so most overseas buyers pay cash or finance in their home country. New houses are operationally the simplest Japanese property to own remotely for the first decade: nothing to renovate, no prior-owner disputes, and the builder is statutorily on the hook for structural defects.
