About UDX
A cross-border digital team, based in Japan
UDX is a digital consultancy in the PROVENANS Group. We run one playbook in two directions: helping Japan-based companies grow internationally, and helping international companies enter and grow in Japan.

Into Japan
Market-fit research, Japanese AI & search visibility, and digital launch execution for international companies entering the Japanese market. Fully remote, delivered in English. See services →
Japanese site
Out of Japan
Overseas digital strategy, marketing, and sales transformation for Japan-based companies expanding abroad — assessments, HubSpot, SEO/AI-search readiness. 日本語サイトへ →
Both directions demand the same rare thing: a team that reads both markets natively. That daily two-way practice is why our Japan-entry work starts from how Japanese buyers actually search, decide, and buy — not from a translated playbook.
Rooted in Japan
We’re not a Japan desk. We’re a Japanese company.
Most Japan-entry advice is produced from outside: an analyst abroad, working from translated sources, telling you what Japan probably thinks. UDX works the other way around. Our core business is running digital marketing for Japanese companies, inside the Japanese market, in Japanese — with offices in Fukuoka, Tokyo, Osaka, and Morioka.
That daily practice is what we bring to your Japan entry: we know which trust signals Japanese buyers check before they purchase, how Japanese media and AI assistants describe brands, and what a Japanese distributor reads between the lines of your website — because reading this market is our home game, not a research assignment.
