Guarantee Perfect Accuracy with a Free Custom Dictionary
True accuracy means using client-preferred terminology. Our Custom Dictionary lets you choose how key names and terms are rendered in French from Japanese. This ensures legal, business, and cultural consistency in all your files—always free.
Brand Integrity
Guarantee that brand and company names like '日産自動車' are always translated as ‘Nissan’ not 'Voitures Nissan' or left in kanji.
Legal & Technical Precision
Set legal terms to comply with French Civil Code or European Directive equivalents. For example: Translate '約款' as 'conditions générales' instead of a literal 'clauses contractuelles'.
Cultural Nuance
Choose how expressions like 'よろしくお願いします' should be adapted (‘Cordialement’, ‘Je compte sur vous’, or another culturally adapted closing).
Industry Consistency
Lock in specific phrasing for recurring phrases in your field (construction, IT, pharma) across all files. For instance, always translate『仕様書』as 'cahier des charges', not 'spécifications'.
Accurate Translations for Every Profession
Avoid costly errors in cross-border business, law, engineering, and more. Our Japanese-to-French AI is tuned for real-world use by professionals in France and beyond.
Legal & Corporate
Scenario:
Translating a contract between a Tokyo manufacturer and a French client in Lyon.
Challenge:
A mistranslation of corporate legal phrases such as '株主総会決議' can create legal risk and invalidate documents under the French Code de commerce or Code civil.
Solution:
Our AI is trained on Japanese-Franco legal corpora and adapts legalese to match French and EU law (e.g., using 'assemblée générale' for『株主総会』), ensuring your intent always holds up.
Business & Finance
Scenario:
Analyzing a financial statement for a French investor reviewing a Japanese startup’s Paris expansion.
Challenge:
Japanese and French accounting standards (J-GAAP vs. IFRS) differ greatly; terms like『決算短信』must be accurately translated to 'communiqué financier' not a literal 'bilan rapide'.
Solution:
Our AI can normalize terminology, identify French equivalents under AMF (Autorité des marchés financiers) standards, and adapt number/date formats to European expectations.
Engineering & Technical
Scenario:
Localizing a user manual for Japanese robotics equipment installed in a Strasbourg warehouse.
Challenge:
Literal renderings like『非常停止』as 'arrêt anormal' instead of the correct 'arrêt d’urgence' can threaten the safety and compliance with French norms (NF EN ISO 13850).
Solution:
Our AI is trained on technical French manuals and Japanese standards (JIS), offering context-appropriate, regulation-compliant translations.
