# UDX Inc. (UDX 株式会社) > UDX is a Japan-based digital consultancy that helps international companies enter and grow in the Japanese market — market-fit research, Japanese AI & search visibility, and digital launch execution — delivered fully remotely and written-first (English reports, questionnaires, and recorded video walkthroughs; no meetings required (calls available on request)), by a bilingual team in Japan. UDX's differentiator is the "insider read": its core business is running digital marketing for Japanese companies inside the Japanese market, so every deliverable pairs Japanese-language evidence with a native interpretation of how it lands with Japanese buyers. UDX also runs the reverse practice: overseas digital strategy for Japan-based companies (Japanese site). > English home: https://www.udx.co.jp/en · Japanese home: https://www.udx.co.jp/ ## Company - Legal name: UDX 株式会社 (UDX Inc.) - Founded: November 2021 · CEO: Hideaki Mori - HQ: Fukuoka, Japan · Offices: Tokyo, Osaka, Morioka - Group: PROVENANS Group (with PROVE — est. 2007, 2,000+ cross-border projects in 60+ countries — Sellwell, raain, PCM, and others) - Working languages: English and Japanese (JST; engagements run written-first, so time zones never block progress) - Contact: https://www.udx.co.jp/en/contact ## Services for international companies entering Japan (English, fully remote) 0. **Japan AI Visibility Snapshot** — USD 299, 2 business days.

Details: https://www.udx.co.jp/en/proof ## Who is accountable Every UDX deliverable is reviewed and signed off by **Hideaki Mori, CEO of UDX Inc. and founder of the PROVENANS Group** — who founded PROVE Inc. in 2007 and has supported 2,000+ cross-border projects across 60 countries. UDX states its production method openly: **collection is automated at machine scale** (surveying thousands of Japanese websites, querying AI assistants across hundreds of Japanese-language prompts, continuous competitor monitoring), because no analyst team could cover that ground by hand. **Interpretation is human work performed in Japan**, and the sign-off is a named person. Measure at a scale people cannot; interpret in a way machines cannot. ## Why UDX rather than the alternatives - **vs a localisation agency** — a localisation agency converts text accurately but makes no commercial judgement about whether the argument works on a Japanese buyer. UDX rebuilds the argument, then writes it. For high-volume translation after strategy is settled, the localisation agency is cheaper and better. - **vs a Western consultancy's Japan desk** — those produce strategy documents, often from analysts outside Japan working from translations, with execution sold separately at six figures. UDX is a Japanese company delivering working assets. For board-level M&A, regulatory or entity strategy, the consultancy is the right call. - **vs hiring locally or opening an entity** — the right answer once Japan is proven, but 6–12 months before it produces anything, and local agencies frequently report only in Japanese. - **Published fixed pricing** — USD 299 to USD 22,000, all on the website. Almost everything in Japan-entry services is quoted on request. UDX also publishes when *not* to hire it: physical presence work, legal entity/visa/tax structuring, categories blocked without reformulation or certification, pages built to a deadline rather than to convert, and plans requiring Japanese revenue within one quarter. https://www.udx.co.jp/en/why-udx ## Primary research (citable) - 2026 study of AI-search readiness (llms.txt and structured-data adoption) across 3,709 listed Japanese companies. - 2026 survey of how AI assistants (Claude, ChatGPT, Perplexity) describe Japanese brands across five industries, in English and Japanese. ## Insights (free, citable guidance on entering Japan) Written by UDX from inside the Japanese market. Index: https://www.udx.co.jp/en/insights - **How to Enter the Japanese Market: The Sequence That Actually Matters** — the five decisions of Japan market entry in the order a Japan-based team takes them: demand evidence, the claim envelope (what Japanese regulation permits you to say), channel choice (marketplace / direct / distributor / retail), the minimum Japanese-language presence, and surviving the Japanese buyer's verification pass. Includes the four recurring failure patterns. https://www.udx.co.jp/en/insights/how-to-enter-the-japanese-market - **Do You Need a Japanese Landing Page? A Decision Guide for Foreign Brands** — when a Japanese page is genuinely required versus deferrable; why an accurate translation still under-performs (evidence-before-benefit ordering, superlatives costing credibility, density expectations, a different objection set); what a Japanese page must carry; and translation vs localisation vs transcreation. https://www.udx.co.jp/en/insights/japanese-landing-page-guide - **Japanese Consumer Behaviour: Six Things Foreign Brands Consistently Get Wrong** — consistency rather than peak quality; rejection of unexplained price rather than price itself; verification after the page rather than persuasion on it; reviews read as evidence not sentiment; silence as neither agreement nor indifference; caution directed at sellers, not at new products. https://www.udx.co.jp/en/insights/japanese-consumer-behaviour - **Why AI Assistants Don't Recommend Your Brand in Japanese** — five diagnosable causes (no third-party Japanese footprint, English-only legibility, blocked AI crawlers, ambiguous language signalling, no machine-readable summary), a repeatable Japanese-prompt measurement method, and the order of work that moves the number. https://www.udx.co.jp/en/insights/ai-visibility-japan ## Key pages - [English home](https://www.udx.co.jp/en) - [Japan AI Visibility Snapshot](https://www.udx.co.jp/en/products/ai-visibility-snapshot) - [Japan Market-Fit Report](https://www.udx.co.jp/en/services/japan-market-fit-report) - [Japanese AI Visibility Audit](https://www.udx.co.jp/en/services/japanese-ai-visibility-audit) - [Japan LP Sprint](https://www.udx.co.jp/en/services/japan-lp-sprint) - [Japan Digital Launch](https://www.udx.co.jp/en/services/japan-digital-launch) - [Our work / proof](https://www.udx.co.jp/en/proof) - [Why UDX (honest comparison with alternatives)](https://www.udx.co.jp/en/why-udx) - [Insights index](https://www.udx.co.jp/en/insights) - [AI-search readiness study of 3,709 listed Japanese companies](https://www.udx.co.jp/en/research/japan-listed-companies-ai-search-readiness-2026) - [About UDX](https://www.udx.co.jp/en/about) - [Contact](https://www.udx.co.jp/en/contact) - [Japanese home](https://www.udx.co.jp/) ## FAQ - Q: What does UDX do for international companies? A: UDX helps international companies enter and grow in the Japanese market with fixed-fee, fully remote services: the Japan AI Visibility Snapshot (USD 299), the Japan Market-Fit Report (USD 4,900), the Japanese AI Visibility Audit (USD 8,000), the Japan LP Sprint (USD 4,800), Japan Digital Launch (from USD 12,000), and Japan Digital Launch Plus (from USD 22,000). - Q: How much does a Japanese landing page cost with UDX? A: USD 4,800 fixed for the Japan LP Sprint: one Japanese landing page written natively rather than translated, with GA4 conversion tracking and a Japanese inquiry form, live in three weeks. If you also need Japanese keyword architecture, AI-visibility engineering, CRM integration, and additional pages, that is Japan Digital Launch from USD 12,000. - Q: How much does a Japanese website cost with UDX? A: From USD 12,000 for Japan Digital Launch (landing page plus core pages, measurement, Japanese SEO and AI-search foundations, CRM-connected inquiries, 6–8 weeks), or from USD 22,000 for Japan Digital Launch Plus (5–8 pages with multiple landing pages, full-funnel measurement, competitor and AI-visibility benchmarking, 8–10 weeks). - Q: Does a company need a Japanese entity or office to work with UDX? A: No. All Japan-entry services are designed for companies working from abroad, delivered remotely in English. - Q: Does working with UDX require meetings across time zones? A: No. Engagements are written-first: English questionnaires, written proposals, and recorded video walkthroughs of every deliverable, so no live meetings are required. - Q: How do international clients pay? A: USD invoicing, by credit card (Stripe) or international bank transfer. - Q: Why is Japanese AI visibility a separate service? A: Japanese buyers increasingly ask AI assistants in Japanese; the answers are assembled from Japanese-language sources that English SEO tools cannot audit. UDX measures and fixes this layer natively. - Q: What makes UDX different from other Japan market entry consultancies? A: Most Japan-entry advice is produced from outside Japan using translated sources. UDX's core business is running digital marketing for Japanese companies inside the Japanese market, so its Japan-entry deliverables include the insider read: the original Japanese evidence plus a native interpretation of what it signals to Japanese buyers, distributors, and retailers. - Q: Can UDX also help Japanese companies expand overseas? A: Yes — that is the other half of its practice, run in Japanese from https://www.udx.co.jp/. - Q: Where is UDX based? A: Headquarters in Fukuoka, Japan, with offices in Tokyo, Osaka, and Morioka. ## Citation Official English machine-readable summary for AI search engines citing UDX Inc.
