Start Your Free Accurate Translation“I am impressed with the precision for legal and technical documents from Portuguese to Japanese. It captures differences in keigo (敬語), company designations like 'LTDA.' and '株式会社', and avoids common errors like literal use of Brazilian titles ('Senhor', 'Doutor')—which generic tools frequently miss.”Prof. Erika Nakano, JP-FCI, ABRATES & Japan Association of Translators

Guarantee Perfect Accuracy with a Free Custom Dictionary
Control terminology: ensure consistent Japanese for your brands, products, or technical terms. Fix legal, business, and engineering terms for every document.
Brand Integrity
Always translate your brand—never generic. Ex: 'Petrobras' stays 'ペトロブラス' (Petoroburasu), not '石油会社' (companhia de petróleo).
Technical Precision
Set the correct Japanese for Brazilian standards, like 'Norma ABNT' = 'ABNT規格' (ABNT kikaku), not just '標準' (standard).
Legal & Regulatory Compliance
Lock in the correct translation for terms like 'CPF', 'CNPJ', and Brazilian labor law (CLT), e.g., 'Cadastro de Pessoa Física' → '個人納税者登録番号'.
Cultural & Linguistic Nuance
Ensure politeness (keigo) and phrase endings always match the formality level for Japanese business or academic scenarios.
Accurate Translations for Every Profession
Avoid critical errors. Our AI is trained for the complexity and rigor of Portuguese–Japanese translation, tailored for legal, technical, and business use-cases.
Legal & Corporate
Scenario:
Translating corporate bylaws from a Brazilian LTDA for a Tokyo-based Japanese partner.
Challenge:
Literal translation of 'Contrato Social' or use of incorrect honorific forms may result in serious misunderstandings—potentially invalidating documents under Japanese Company Law (会社法, Kaisha-hō).
Solution:
Our AI is trained on Brazilian and Japanese legal corpora—mapping cross-jurisdictional concepts and preserving keigo for full compliance.
Industry & Trade
Scenario:
Translating technical data sheets for machinery exported from Brazil to the Port of Yokohama.
Challenge:
Tools may mistranslate units (kgf/cm², N·m), local risk phrases (e.g., 'Risco de choque elétrico'), and maintenance warnings, affecting operation and safety under Japanese Industrial Standards (JIS).
Solution:
Our AI maps Brazilian and Japanese technical terminology, converts and normalizes units, and always delivers appropriate Japanese warnings and format.
Academic & Scientific
Scenario:
Translating a thesis or scientific paper for submission to a Japanese journal.
Challenge:
Incorrect politeness or formatting could result in a desk rejection. Subject-specific terms (e.g., 'Biodiversidade da Amazônia') must map to standard Japanese ('アマゾンの生物多様性').
Solution:
Academic Japanese style and proper referencing are enforced, while terms from Brazilian academia are matched to widely-understood Japanese equivalents.
