Taisei Jutaku — custom homes, renovation, and real estate in Sasebo and Saza, Nagasaki
Just right for you,
built with real skill.
Line Up
Two ways to build new
We build two kinds of custom homes. Kizahashi is semi-custom — you choose from proven floor plans. Atsurae is full custom — an architect designs the house from a blank sheet. Beyond that, we also work directly with architects on more design-led projects.
Semi-Custom
Kizahashi
Choose what's right for you.
A semi-custom line built from five design directions and floor plans with a track record. Choosing from proven options means fewer surprises, and the total cost is clear from the first estimate.
Full Custom
Atsurae
Made just for you.
No preset plans. Our own architect meets you directly, listens to how your household lives, and draws the plan for that one house alone — from the shape of the roof down to the smallest built-in detail.

Imported and reinforced-concrete homes
Two more ways to build, when the structure itself is part of what you want
We also build Canadian-style imported homes using platform-frame construction for high insulation and airtightness. Reinforced-concrete (RC) construction is available for households that want that structural style.
Why households choose us
What a local builder can do that a national brand cannot
One team, from first meeting to handover
Licensed architects and site supervisors work with you directly from the first meeting through handover. We do not split the project between a separate sales, design, and construction team.
The total cost, in the first estimate
We give you a full estimate before you sign a construction contract, and we design the finishes around that budget rather than adding costs as the project moves forward.
Read more →Engineered for earthquakes, insulated for the climate
Every construction method we offer is engineered against a defined seismic standard, with the highest grade available as an option. Insulation and airtightness are designed around the Nagasaki climate.
Read more →A local company that stays local
Taisei Jutaku has been based in Saza Town, Nagasaki, since April 1992, and we build, renovate, and sell property across Sasebo and the surrounding area.
Read more →Beyond new construction
We handle real estate (land, resale homes, and brokerage), renovation from a single room to a full renovation, and inspection or maintenance for homes we did not originally build.
Renovation
Renovation and demolition
From a kitchen or bathroom update to a full renovation — on homes we built and on homes we did not.
Real Estate
Real estate: buy, sell, inherit
A builder that also holds a real estate brokerage license. Land, resale homes, selling, and inherited property.
What clients say
Feedback from households who built with Taisei Jutaku
From the first meeting to the finished house, everything was handled carefully. Every small request was worked in, and the result was better than we expected. We're genuinely glad we chose Taisei Jutaku.
S., Saza Town
We chose them for the design at first sight. The insulation is strong, so the house stays warm all winter, and our utility bills dropped compared to our old apartment. Every request was worked through one by one, and the staff were kind throughout.
K., Sasebo City
As a local company, they helped from the land search onward. The after-service since move-in has been thorough, and we live here with real peace of mind. I'd recommend them to a friend without hesitation.
Y., Hasami Town
Before you start
The parts of the process that are easiest to get stuck on
How we work
Our approach is simple: the engineers deal with you directly.
It started with a client telling us that the clearest answers about a building site come from the people actually working on it. If that is true, then the engineer should be in the room from the start, and the money saved on a separate sales layer can go into the building instead.
We build fewer houses a year that way, but we can give each one real attention. We have been in Saza Town since April 1992, and the engineers here know this area's climate, soil, and land.

Frequently asked questions
Of course. Call us or use the contact form, and a licensed architect or site supervisor will answer you directly, so technical questions get answered on the spot rather than passed along.
A mortgage with zero down payment is possible. That said, the bigger your down payment, the smaller your loan and the easier your monthly payments. Plan on paying incidental costs, such as registration fees and fire insurance, in cash — typically five to eight percent of the purchase price. We build the financing plan around your actual savings, so start by telling us where you stand.
We carry statutory defect-liability insurance, which covers the structural frame and the parts that keep rainwater out for ten years after handover. If something goes wrong within that coverage, we respond quickly.
Yes, that's actually the common case. You'll need to be present, or arrange to be, when prospective buyers view the house, but we schedule those around you. If you're selling while still living there, keeping the plumbing areas clean and decluttering makes a real difference to how the house shows.
Contracts and the legally required disclosure statement are prepared in Japanese only.
