This guide is for US companies entering Japan: the expansion lead responsible for sales, the founder launching a new venture, the owner trying to reach Japanese customers. It lays out how to choose a partner, and how to vet one, based on data and the industry’s real mechanics.
A Polished Site That Gets No Inquiries Has Structural Causes
Here is an uncomfortable pattern worth knowing before you hire anyone. Many vendors that build websites for the Japan market do not rank well for their own services. It is common to find a firm that has been in business for many years, carries a respectable domain rating, and still attracts only a handful of organic visitors a month. A company that builds sites is not automatically a company whose own site works as a lead engine.
That gives you a simple, powerful vetting step. Before you sign with anyone, spend 5 minutes looking up the vendor’s own domain in a tool like Ahrefs and check two things: their organic traffic and their domain rating. If the people you are about to pay to win you traffic cannot win their own, treat it as a signal. To build a Japanese site that actually converts, you want someone who understands SEO, AEO (Answer Engine Optimization), and GEO (Generative Engine Optimization), and who can direct AI from the design stage forward.
It helps to know how the core number works.
- Domain Rating (DR) is Ahrefs’ 0 to 100 score for how strong a domain’s backlink profile is, used as a proxy for how much Google trusts the site.
- DR 0 to 20: new or early-stage. Winning big keywords is hard here.
- DR 20 to 40: some content and links built up. Competitive on middle keywords.
- DR 40 to 70: mid-size to large media. Big keywords come into range.
- DR 70 and up: major news sites and known brands.
Why Hours-Stacked Quotes Are Being Rethought
Most quotes from web vendors are hours-stacked: director so many hours, plus designer, plus coder, plus writer, plus SEO lead. It looks transparent, and it costs far more than an AI-driven build. A traditional multi-person team building a 7-page corporate site runs about 120 hours, 3 to 5 people, and 6 to 10 weeks. A professional who understands SEO, AEO, GEO, and LLMO and uses AI to produce equivalent quality increasingly finishes the same work in about 35 hours, with 1 person, in 1 to 2 weeks. That is close to 3.4 times fewer hours, and a larger gap on a labor-cost basis. The full hour-by-hour comparison is here.
Hours-stacked quotes survive partly because buyers do not see AI’s real productivity impact. The bigger reason sits on the vendor’s side. They know AI can cut the hours sharply, but adopting it openly would shrink their own billings, so it rarely shows up in the estimate. There is payroll to keep covered. Industry research backs the gap that good AI use creates: a Bain & Company 2025 report found teams that merely adopt an AI coding assistant gain 10% to 15% in productivity, while companies that integrate AI across the whole process reach 25% to 30%. Forrester estimates that an optimal human-and-AI split cuts development cost 15% to 20%. The lesson is that the skill to design with AI, not the act of using it, is what changes the cost structure.
Know the White Label Structure
AI agents have made this harder to justify. Work that used to take a full person-month, like market and competitor research, now finishes in roughly a tenth of that time, so a cost structure built on layers of subcontracting carries less logic than it used to.
Don't Choose on Company Size Alone
The larger the company, the more overhead gets folded into your project: office rent, indirect staff, sales and accounting and HR, several layers of management. None of it appears as a line item, but it is all in the math somewhere. A mid-size US agency’s overhead can run 30% to 50% of revenue, and once you add the white label margin of 40% to 60%, the share of your payment that reaches actual production gets surprisingly small. Choosing purely on headcount tends to hide your real return.
A more useful lens for the AI era weighs the individual’s AI skill and track record over the company’s size. One senior specialist who has AI generate the market research, competitive analysis, English and Japanese draft copy, and even coding starting points, then integrates, judges, and edits all of it, can finish to the same standard as a traditional multi-person team, often faster and with more consistency.
The Real Test: Can They Visualize the Market With Numbers?
- your site’s current domain rating
- how the competitors’ domain ratings are distributed
- how many times your target audience searches each month, in both English and Japanese
- where the winnable keyword space actually is
- what is breaking in your current traffic paths and conversion
When the discussion is built on numbers and charts, it stops being a matter of opinion and the strategic priorities get clear. As a real example, in the US market today website localization gets about 800 searches a month at a keyword difficulty of 6, how to choose a web development company sits at 200 searches and a difficulty of 0, japan market entry at 150 and 0, and website localization cost at 150 and 0. Finding and reading numbers like these takes someone who has actually analyzed the competitor domain-rating landscape for the Japanese market, not just pulled a figure from a tool.
There is a second factor that decides projects: being able to talk to, and contract with, that specialist directly. When several intermediaries sit between you and the work, the deep conversation a strategy needs becomes hard to have. What is our win path in Japan? Which search intent do we serve first? Which keyword do we attack first? Those answers take shape through careful back-and-forth with the individual who is actually doing the work.
The research lines up with this. A Figma 2025 AI report found 78% of developers and designers felt AI improved their efficiency, while only 40% of designers felt it improved quality. Google’s DORA 2025 report concludes that the real gains from AI go to teams with deep expertise and established workflows. AI carries the speed and the volume; an experienced individual carries the quality and the judgment. When that split works, a website project in Japan turns into real results.
One Criterion to Add Before You Decide
This is how we work. At JU Marketing, you deal directly with one senior bilingual specialist who talks with you, then runs the market and competitor analysis visualized with Ahrefs and Google Search Console, the content design, Japanese SEO, the design judgment, and the ongoing operation, end to end. There is no team to coordinate and no handoffs to lose quality in.
Compare that to hiring. A person with this combination of skills would command a high six-figure US salary, and you would still add recruiting, training, and management on top, and still need them to be bilingual and fluent in the Japan market. Engaging a senior specialist who already has all of it, and who directs AI to do the heavy lifting, puts that capability on your side as a member of your team, without the organizational overhead. If you are planning a Japanese website build, the build service and a free consultation are the place to start.
