Our work
Don’t take our word for it. Open the sites.
Most agencies show you a portfolio. We’d rather show you three Japanese businesses whose entire digital operation runs on work we do — live, in Japanese, inspectable right now. All three are companies in our own group. We’re telling you that first, because the point isn’t a testimonial. It’s that you can go and check.
Why we show you group companies instead of client logos
A Japanese client testimonial is close to useless to you. You can’t read it, you can’t call them, and you have no way to judge whether the site behind it is any good. So it comes down to trusting our translation of our own praise.
The three properties below are different. They are live Japanese-language businesses. You can open them, run them through any tool you like, view the source, check the structured data, look at how the funnels are built. Nothing is staged for this page.
And because they are our own group’s companies, our own revenue depends on this work performing. That is a stronger guarantee than a quote from a happy customer.
Three Japanese properties we build and operate
Every one is in Japanese, aimed at Japanese buyers, and measured. This is the same work we would do for you.
Group company · est. 2007
PROVE Inc. — cross-border consultancy
A Japanese consultancy with 2,000+ cross-border projects across 60 countries since 2007. We run its entire digital operation.
- Data Hub — a public Japanese-language market data explorer, built and maintained by us
- Data Pulse — behavioural analytics on what visitors actually search and read
- Lead nurturing — segmented Japanese email programmes wired to the CRM
- Editorial — ongoing Japanese content with a fact-check gate before anything publishes
- Measurement — GA4 and tag architecture rebuilt from the ground up
Group company
Sellwell Inc. — domestic sales & marketing
A Japanese sales and marketing firm. We built and run its acquisition engine.
- Subsidy Finder — an interactive Japanese tool covering all 47 prefectures, built as a lead magnet
- Diagnostic funnel — a self-assessment that qualifies visitors before they ever speak to sales
- Data Pulse — the same behavioural reporting layer, adapted to a different business
- Mobile-first rebuild — because Japanese B2B research happens on phones more than foreign teams expect
This company
UDX Inc. — the site you are on
The clearest test of whether we can do this: our own Japanese presence.
- Digital Intelligence Hub — a public dashboard tracking AI-search readiness across every listed company in Japan, refreshed continuously
- 100+ Japanese articles — a working content engine, not a neglected blog
- Full LLMO implementation —
llms.txt, structured data,hreflang, AI-crawler policy. We ship on our own site what we sell to you - This English site — including the page you are reading, built on the same stack we would build yours on
Research nobody else is publishing
We machine-surveyed the official website of every domain-resolved company listed on the Tokyo exchange — 3,709 of them — to establish how ready Japan actually is for AI search. Methodology is published in full; the data refreshes on a rolling basis.
| Companies surveyed | 3,709 |
Have adopted llms.txt | 4.5% |
| Homepage structured data | 29.0% |
| hreflang implemented | 12.5% |
This is where automation earns its place in our work: no team of analysts is checking 3,709 websites by hand. Machines collect at scale; people decide what it means. Read the study and methodology →
