KAIZEN Digital OÜ was founded in August 2025 by Rie Sakurai, a bilingual Japanese SEO and content specialist. The team has hands-on experience supporting global brands including Swarovski, Workday, Semrush and Thomson Reuters on their SEO and marketing work.
Most of the companies we work with are technical B2B manufacturers and industrial suppliers with revenue between €20M and €300M. They sell products where specifications, quality documentation and test data decide the deal. They already have one live connection to Japan: a customer, an inbound enquiry, a distributor, or a Japanese competitor winning against them. And they have nobody in-house who works in Japanese.
KAIZEN Digital OÜ was founded in August 2025 by Rie Sakurai, a bilingual Japanese SEO and content specialist. Client work before and alongside the company has included Swarovski and Workday, on Japanese-language search, content and localisation.
“There are not a lot of bilingual Japanese SEO specialists.” Rie Sakurai, in an interview with estx.
The company is registered in Estonia under the country’s e-Residency programme, registration number 17300491. That structure keeps overheads low and the operation location-independent, which is what allows a small team to work across European time zones and Japanese business hours in the same week.

Research behind a Japan decision has to hold up when a buyer pushes back on it. Our approach is built around that. Consultants do the judgement work, and software handles the volume.
Software speeds up the mechanical parts of research: gathering candidate sources, processing large volumes of Japanese-language material, and tracking search and social data over time. It does not decide what is true.
Every figure that reaches a deliverable is checked by opening its primary source, not by trusting a citation that arrived attached to it. Beyond verification, our consultants do the work software cannot: reading why an approach succeeded or failed in Japan, interpreting what a buyer’s silence means, and placing market shifts in their cultural and economic context.
The gap we work in sits between how an international company presents itself and what a Japanese buyer needs to see. In practice that means writing and reviewing Japanese correspondence, documents and presentation material, interpreting online meetings and handling the follow-up, and advising on how something should be phrased and how the other side is likely to read it.
Naming the boundary is more useful than implying full coverage. The following sit with licensed professionals in Japan. KAIZEN Digital OÜ can introduce you to them and handle the Japanese-language side of working with them, but does not perform this work.
Work visa sponsorship. The domain of an immigration lawyer or a licensed administrative scrivener (gyoseishoshi).
Company incorporation and registration. The domain of a judicial scrivener (shiho-shoshi).
Tax and legal advice, and tax filing. The domain of a licensed tax accountant (zeirishi) or a lawyer.
M&A sourcing, due diligence and deal execution.
Clearing regulatory and certification gates. KAIZEN Digital OÜ maps which gates apply to your product. The determination on any individual gate belongs to a qualified specialist.
KAIZEN Digital OÜ also holds no authority to commit your company to anything.
The name KAIZEN Digital OÜ reflects our core philosophy of continuous improvement, deeply embedded in both our internal processes and client relationships. We actively seek and integrate feedback from every engagement, constantly refining our methodologies and enhancing our service delivery.
We do not just deliver consulting services. We work alongside your team long enough to see a Japanese pipeline move. Feedback from each engagement changes how we run the next one, which is what the name KAIZEN refers to.
We treat client relationships as long engagements rather than one-off deliverables. The goal extends beyond market analysis and strategic planning: the measure of the work is whether your Japanese pipeline moves. A deal that closes in Japan and would not have closed otherwise is the result we work toward.
We help foreign companies succeed in the Japanese market through data-driven strategies, localized marketing, and digital solutions tailored to your goals.
