In Japan, buyers drop you when no company like theirs is in your case studies

Your Japan team asked for case studies. HQ approved a translation budget, localized eight of the global customer stories, and shipped them.

Six months later, Japanese prospects still ask the same question on the first call: “Which Japanese companies our size use this?”

The problem is not the translation. It is that your library was built to answer a different question than the one Japanese buyers are asking.

What a case study is used for in Japan

In Japan, a case study is screening material, not persuasion material.

The joint study by IDEATECH and Hiroyasu Kitagawa (Demagen Institute), published 16 April 2026, surveyed 307 employees and executives at Japanese B2B companies who had been involved, with at least one colleague, in a purchase with an annual contract value or one-time implementation cost of 3 million yen or more in the previous 12 months. Fieldwork ran 23–26 March 2026. It is research PR from IDEATECH, and the screening criteria skew it toward large, multi-stakeholder deals, so read it as data on that segment.

Two findings sit on either side of the same behavior.

Among reasons for dropping a vendor from consideration (multiple answers, n=307): missing functionality 39.1%, “the company did not seem to fit our size” 34.5%, and “there was no company similar to ours in their case studies” 26.4%.

Among factors that mattered when the eventual winner was first added to the shortlist (n=298 for this question, up to three answers): “they had a case study from a company similar to ours in size” 44.3%, “the functionality addressing our problem was clear” 40.3%, “they had implementations in our industry” 29.5%.

Industry-specific information, meaning vertical case studies and industry-specific feature explanations, influenced shortlisting for 62.5% of respondents (16.9% “it was the deciding factor” plus 45.6% “it pushed the decision forward”).

A Japanese buyer opens your case study page to check whether you serve companies like theirs. If the answer is no, that is a disqualification, not a missed opportunity to inspire.

Three reasons the global library does not transfer

First, the logos are the wrong evidence. A page of US enterprise names does not read in Japan as “this vendor is credible.” It reads as “this vendor sells to companies unlike ours.” The 34.5% who drop vendors on perceived size mismatch are reading your customer list as size evidence, and translating it does not change what it says.

Second, the reader is usually not the decision maker. In the same study, 60.9% of deals went through a two-stage approval (department head plus executive), and more than 80% went through two stages or more. The person reading your case study is assembling material for people who will never visit your site. A narrative about transformation does not survive being pasted into a ringi document. Specific figures, headcount, deployment time, and the internal objection that was resolved do survive.

Third, global libraries are organized by product or use case. Japanese buyers screen by industry and company size. The same content, reorganized by Japanese industry category and employee-count band, gets found; organized by “Enterprise Automation” it does not.

The six questions your Japan case studies must answer

Do not translate the stories. Commission new ones, and fix the interview questions.

1. Scale and structure. How many people use it, and which department (name and headcount) operates it day to day. This is the first thing a Japanese reader matches against, so it belongs above the fold, not in a footer.

2. The before state, in numbers. How much time and how many people the work took before. “Significantly improved” with no starting point is not screening material.

3. The comparison. How many vendors were evaluated and why each was ruled out. This is the buyer’s own selection logic, and readers overlay it on their own comparison sheet.

4. How it got approved internally. Who objected, and what evidence resolved the objection. In a market where 80%+ of deals clear two or more approval stages, this is the paragraph that gets reused.

5. Time to running. Days from contract to actual use, and how much of whose time the customer had to commit. When implementation load is invisible, readers substitute their worst assumption.

6. What stopped. Which task the team no longer performs. Behavior change travels better than a metric a reader cannot verify.

Agree the publishable level of detail at the start of the interview, not at the end. Many Japanese customers will not allow their name to be used, and HQ often reads “no named logo” as “no case study.” That is a false equivalence. An anonymized story that states industry, employee band, seat count, operating department, and deployment days does the screening job. A named logo with no numbers does not.

What HQ should do differently

Stop treating Japan case studies as a localization line item. They are a market-entry deliverable, and they are on the critical path: without one, your Japan team is asking buyers to be the first, in a market that screens on precedent.

Three changes. Budget the first two or three Japanese customer stories as part of the entry plan, with the six questions above as the required fields. Reorganize the Japan case study index by industry and employee-count band rather than by product line. And measure your Japan marketing team on whether local sales can answer “which company like ours uses you” in one sentence, not on how many assets were translated.

There is no published benchmark for how many Japanese buyers a missing local case study costs you; nobody has measured it. What is measurable is your own funnel: count how many Japan opportunities went quiet after the first request for a local reference.

A case study in Japan is not a story, it is screening material. Localize the questions you ask customers, not just the language of the stories you already have.
