We’ve already written about why you might want to build a property rather than buy a pre-existing one in Tokyo (you can read more about that here, but the TL;DR is: it’s cheaper, faster, and in many ways easier than abroad – in places like the US or the UK).
The next step, if that’s the approach you choose to take, and you’ve found your plot of land, is to choose a house builder.
Several factors determine the price of a custom build, so these are general guidelines. What really separates these companies is how they approach design, what materials they use, and their underlying construction philosophy.
With that being said, here’s a breakdown of Tokyo’s major homebuilders – organized by price by tsubo (3.3m2 or 35.58ft2) – and what sets them apart in terms of design, materials, and philosophy.
Low-End Builders (Around ¥800,000 per Tsubo)
At this price point, you’re looking at standardized designs with limited customization. These builders usually work from pre-set floor plans with fixed material packages. Construction quality meets Japanese building codes (which are strict), but you may not find premium finishes or architectural flexibility.
This tier makes sense if you’re budget-conscious, don’t need custom features, and prioritize getting a new, code-compliant house at the lowest possible cost.
Open House
Open House is ideal for buyers who prioritize location and efficiency over extensive design freedom. Their homes are built fast — often within three to four months — and are designed to maximize compact city plots.
While customization options are limited, the streamlined process and bundled land–house packages make them a strong choice for first-time homeowners or investors looking for a quick, low-stress entry into Tokyo’s property market.
- Specialty: Cost-efficient urban homes on small plots
- Common Materials: Reinforced wood or light steel frames; synthetic siding
- Design Traits: Compact, prefabricated layouts optimized for narrow lots
- Ideal For: Investors and first-time homeowners
- Notes: Known for turnkey developments where land and house come as a set package; minimal customisation but rapid delivery (3–4 months typical).
Mid-Range Builders (Around ¥1,500,000 per Tsubo)
Mid-range builders offer semi-custom designs, where you work from their base plans, but with room to adjust layouts, upgrade finishes, and make the house feel more personal.
Many buyers land in this range because it strikes a balance between cost andge because it balances cost with livability. You’re not locked into predefined layouts, and the build quality reflects attention to detail that extends beyond just meeting code.
Misawa Homes
Misawa Homes stands out for families seeking a balance between technology and comfort. Their modular construction allows for moderate customization while maintaining strong insulation and durability. Build times are typically 4–6 months, and their homes excel in long-term livability — a reliable choice for those who want quality without the premium price of bespoke architecture.

- Materials: Steel-framed modular panels with advanced thermal insulation
- Design Focus: Comfort and energy savings; family-oriented designs with customizable interiors

Toyota Homes
Toyota Homes offers engineering precision and factory-level consistency. Their steel-frame houses are built with the same philosophy as their automobiles: safety, reliability, and performance. Timelines are predictable, and quality control is among the best in the industry.

High-End Builders (Around ¥2,300,000 per Tsubo)
At this level, you’re paying for architectural freedom and premium everything. High-end builders treat each project as a custom job where your architect or their in-house design team works from scratch. The build process takes longer, but you’re getting craftsmanship and design consideration that shows in every room.
This tier attracts buyers who want a house tailored to how they actually live, not how a floor plan assumes they will. Expect detailed consultations, multiple design revisions, and builders who can execute complex requests, whether that’s integrating traditional Japanese elements, maximizing natural light on a difficult lot, or future-proofing for aging in place.
Mitsui Home
Mitsui Home is the go-to choice for those wanting warmth and refinement without sacrificing engineering integrity. Their wooden structures allow for a higher level of customization and aesthetic flexibility, with project timelines usually ranging from 6–8 months.

Luxury Tier (Around ¥3,000,000 per Tsubo and Up)
These projects often involve well-known architects, master craftsmen specializing in traditional techniques, or firms known for pushing contemporary design boundaries. The timeline extends considerably, 12 to 18+ months isn’t unusual, because everything is considered, refined, and executed to exacting standards.
Clients at this level typically aren’t comparing price per tsubo across builders; they’re choosing based on portfolio, reputation, and whether the firm can realize their particular vision.
Private Architects
For those seeking individuality above all else, private architects deliver a lot more by way of creative freedom. Every material, line, and light source can be tailored to your taste.
These projects take time — usually 9–14 months — but the process is collaborative and deeply personal. Ideal for design-forward clients wanting a statement home, these builds are one-of-a-kind creations that reflect their owners’ vision and personality.
