Japanese B2B buyers complete most of their supplier evaluation before the first meeting, through nemawashi (根回し) — internal consensus built quietly, before any external contact. METI reported that 43.1% of Japan’s B2B transactions were already conducted electronically in 2024, so much of that evaluation runs against your Japanese-language footprint rather than your pitch.
By the time a Japanese procurement manager shakes your hand at a trade show, they are usually confirming a judgement rather than forming one. This article sets out what they check before any meeting, why compliance reads as a trust signal in Japan, and what to fix before your next show.
When does a Japanese B2B buyer actually start evaluating you?
Long before the meeting, and without telling you. Evaluation begins when someone inside the buying company starts building internal agreement — the nemawashi process — and by the time you are contacted, an internal position usually already exists.
This is why the Japanese cycle runs longer than the Western one. In a consensus model, the external conversation starts after the internal one has largely concluded, so what looks like a slow decision is often a decision that was made in a room you were never in.
Where does that evaluation actually happen?
On screens, in Japanese, before anyone speaks to you. Japan’s business-to-business commerce is already substantially digital, which means your Japanese-language surface is the artefact being audited.
Japan’s Ministry of Economy, Trade and Industry (METI) put the domestic B2C e-commerce market at ¥26.1 trillion in 2024, up 5.1% year on year, and reported the B2B e-commerce ratio at 43.1% of all B2B transactions (METI, Market Survey on Electronic Commerce, published August 2025). Close to half of Japanese B2B trade now passes through channels where your Japanese copy, or its absence, is the only thing speaking for you.
What do Japanese buyers research about you before contact?
Five things, in roughly this order: your Japanese-language web presence, verifiable certifications, industry-association visibility, local legal presence, and peer reputation. None of them is about your product.
| What they check | What they are testing | What fails it |
|---|---|---|
| Japanese-language site | Is Japan a priority, or an afterthought? | English-only, or machine-translated Japanese |
| Certifications | Can the claim be verified independently? | “High quality” with no certificate number or issuing body |
| Industry association presence | Is this a relationship or a transaction? | No trace in any relevant Japanese association |
| Local entity or partner | Who is accountable inside Japan? | No Japanese entity, no named partner, no importer of record |
| Peer reputation | What do their existing contacts say? | One unresolved negative reference |
1. Japanese-language web presence
A website in English only — or worse, machine-translated Japanese — reads as a statement that Japan is not a priority market. Japanese buyers expect at minimum a three-page site in native-quality Japanese: a company overview (kaisha annai / 会社案内), product or service pages with specifications, and contact information reachable from Japan.
2. Verifiable certifications
Japanese companies do not take quality claims on trust; they check the certificate. Expect scrutiny of ISO certificates by number and issuing body, of PSE marking for electrical products, and of residue compliance for food and agricultural goods.
3. Industry association visibility
Membership in a relevant Japanese industry association — or even attendance at its events — reads as long-term commitment rather than opportunistic selling. It is one of the cheapest visible signals available to a new entrant.
4. Local entity or registered partner
A registered Japanese entity (株式会社 / 合同会社) or a documented Japanese partner answers the question of who is accountable locally. For regulated categories this is not preference but law: under the Electrical Appliances and Materials Safety Act, businesses that manufacture or import regulated electrical appliances must file a notification, which makes them the notified business (todokede jigyōsha, 届出事業者) (Electrical Appliances and Materials Safety Act, Act No. 234 of 1961, Chapter 2, e-Gov Japanese Law Search). Our PSE certification and notified-business guidance for Japan covers that filing path in detail.
5. Peer reputation
Japanese business runs inside tight industry networks. Buyers ask colleagues, association contacts and sometimes competitors about their experience with you, and a single unresolved negative reference can end the conversation before it opens.
Why does regulatory compliance read as a trust signal in Japan?
Because compliance is the one claim a Japanese buyer can verify without your cooperation. A certificate number can be checked; a statement about quality cannot.
Food and agricultural exporters meet this most directly through the Positive List system, introduced by Japan’s Ministry of Health, Labour and Welfare on 29 May 2006, which prohibits distribution of food containing agricultural chemicals above a set level where no maximum residue limit has been established — with a uniform limit of 0.01 ppm applied to substances that have no MRL of their own (MHLW, Introduction of the Positive List System for Agricultural Chemical Residues in Foods).
Read commercially rather than legally, that rule tells a buyer something useful: a supplier who has already worked out its residue position has done homework that most first-time entrants have not. The same logic runs through every regulated category, which is why cross-border compliance belongs at the front of a Japan plan rather than at the end of it.
Why does product quality alone not get you a meeting?
Because the buyer cannot evaluate quality until they have decided you are worth the evaluation. Japanese B2B decisions are built on visible, verifiable commitments, and product performance is only assessed after those commitments have been seen.
This explains a pattern many foreign companies experience. You exhibit in Japan, exchange fifty business cards, send follow-up emails to every contact — and receive nothing. The silence is not rudeness. It is the outcome of a pre-meeting review you did not know was running and did not pass.
Japanese buyers typically build a shortlist of booths to visit before the show opens. If you are not on that list, a card exchanged at the booth does not move you onto it, and a follow-up email in English with no verifiable Japanese footprint only confirms the original read.
What should you fix before your next Japan trade show?
Five things, all of which are visible from outside your company and none of which requires a Japanese office.
1. Build a Japanese website, even a small one
Three pages in native-quality Japanese beat a fifty-page English site. Commission a native Japanese writer — not a translation tool — for the kaisha annai, the product pages and the contact page.
2. Format certifications to Japanese expectations
Certificate number, issuing body, validity dates and scope, presented together on a dedicated certifications page in Japanese. The goal is that a buyer can verify you without emailing you.
3. Attend one industry association event
Attending as an observer is enough to register as present. JETRO’s databases and the chambers of commerce in Japan are the practical starting points for finding the right association.
4. Establish an accountable local presence
This does not have to mean an office. Registering a 合同会社 or 株式会社, partnering with a Japanese trading company, or having a Japan-based company act as importer of record for regulated goods all answer the accountability question.
5. Produce a Japanese company profile
A downloadable kaisha annai PDF in Japanese is standard practice, and it is what gets forwarded internally during nemawashi. Include company history, key products, certifications, and how you serve Japanese clients.
Frequently asked questions
How long does entering the Japanese market take?
Longer than a Western cycle, because the internal consensus stage happens before you are contacted rather than after. Plan the schedule around the buyer’s approval sequence — nemawashi then formal ringi — rather than around your own sales stages, and treat any single published benchmark as indicative rather than binding.
What certifications do Japanese buyers look for?
It depends on the category. Common ones are ISO 9001 in manufacturing, PSE marking for electrical products, and Positive List residue compliance for food and agricultural goods. Verify the specific requirement for your product with METI or JETRO before you quote, not after.
Do I need a Japanese website to sell in Japan?
Not legally, but practically yes. Japanese B2B buyers run their due diligence in Japanese, and the absence of a Japanese-language presence is read as a lack of commitment rather than as a gap in your marketing budget.
How do Japanese companies evaluate foreign suppliers?
Through online research in Japanese, certificate verification, informal reputation checks inside industry networks, and an assessment of who is accountable in Japan. The process is methodical, consensus-driven, and almost entirely invisible to the supplier being assessed.
What is the biggest mistake foreign companies make entering Japan?
Assuming product quality is sufficient. Trust signals — Japanese web presence, verifiable certifications, local accountability, industry visibility — are assessed first, and a supplier that fails them never reaches the stage where the product is judged at all.
Is a price advantage enough to win a Japanese buyer?
Rarely, because price is evaluated last. A supplier that cannot be verified is not a cheaper option in a Japanese buyer’s model; it is an unquantified risk, and discounting does not reduce that risk.
