A practical Japan guide to jurisdiction, applicable law, evidence, Google policy and proportionate escalation when a harmful review crosses borders.
Why Fact Versus Opinion Is The First Legal Question
A review can be written in one country, target a business in Japan, be read elsewhere and remain hosted through a global platform. Those connections do not automatically answer where a claim may be brought or which law applies. Separate the reviewer's location, the business and audience, the place of reputational harm, the relevant Google service and any contractual or employment relationship. Local rules on jurisdiction, applicable law, corporate reputation, limitation and remedies must then be checked rather than imported from another country.
Labels do not decide the issue. Writing “in my opinion” does not automatically convert a concrete accusation into protected opinion, while a vivid phrase may be obvious exaggeration when read with the star rating, images and surrounding narrative. A disciplined file identifies the implied facts supporting the evaluation, what the reviewer appears to claim first-hand, and what can actually be proved or disproved. That classification guides platform reporting, public response and any legal advice; it does not promise removal or a court outcome.
Evidence Checklist: Test Each Sentence, Not The Overall Tone
Preserve the review URL, profile, exact language, translations, publication and edit times, images, owner replies and the business-profile location. Record only supportable cross-border connecting factors: known author location, customer or employment records, where the service occurred, audience and booking data, markets in which the review was surfaced, measurable enquiries or losses, and every Google report or appeal reference. Keep original-language captures and explain how translations were produced; do not guess identity or location from a name, flag or profile photo.
Match each factual proposition to contemporaneous material: contracts, bookings, invoices, payment and refund records, service logs, messages, policies, staff rosters and lawful CCTV retention. Record gaps as carefully as contradictions. Do not publish confidential customer files merely to win the public argument. If translation matters, preserve the original language and a careful working translation. The Google-facing packet should contain only the shortest non-confidential material needed for the chosen policy category; the fuller chronology belongs in the internal or lawyer file.
Google Policy And The Local Legal Frame
Google says a review is not eligible for removal merely because a business disagrees with it. The policy analysis should therefore remain separate from the local defamation analysis. A genuine but harsh opinion may comply with policy. A review may instead fit fake engagement, misrepresentation, harassment, personal information or another rule when the facts support that category. A legal request is a different route and should identify the exact URL, exact passage, local right relied on and why the requested action is proportionate.
For Japan, the working legal source is Japan Civil Code, Articles 709 and 710. It should be read with current local case law and procedure before any formal notice. Depending on the jurisdiction and context, the distinction may involve truth, honest opinion or fair comment, serious harm, reputation of legal persons, privacy, insult, public interest and available defences. Businesses should avoid copying a legal test from another country or treating a policy rejection as a final judicial decision.
A Public Response That Does Not Worsen The File
A public answer should usually be shorter than the evidence file. It can acknowledge the concern, say that the business is checking the matter against its records and invite the reviewer to a verified private channel. Avoid repeating the most damaging allegation, exposing personal data, calling the reviewer a liar or threatening proceedings before the classification and proof are complete. A restrained reply preserves options and reduces the risk that the business creates a second harmful publication of its own.
When Escalation Deserves Local Legal Review
Seek coordinated local advice before naming a foreign reviewer, serving a notice abroad, seeking disclosure, relying on a foreign order or beginning proceedings. Jurisdiction and choice of law may differ from enforceability, platform moderation and cross-border service. Check treaty membership, reservations and local procedure rather than assuming the HCCH Service Convention applies. Avoid forum shopping, inflated worldwide-loss claims, mass notices, threats of criminal process or statements that Google must remove content everywhere.
Closer local review may be justified when a passage alleges crime, fraud, professional misconduct, unsafe treatment or regulatory breach; names staff; discloses private information; affects licences or financing; appears across coordinated profiles; or is linked to threats or extortion. Escalation should still be staged: preserve, classify, report under the narrowest honest policy ground, assess a correction request or legal notice, and consider proceedings only with local advice on evidence, deadlines, jurisdiction, cost and proportionality.

Practical Conclusion
Treat the dispute as a map of facts, law and remedies. Preserve the publication, identify genuine connecting factors, separate Google policy from local illegality, compare realistic forums and choose the narrowest proportionate route. A disciplined cross-border file can improve reporting, notice and litigation decisions, but it does not guarantee jurisdiction, service, enforcement, removal or legal success.
