The accuracy for Japanese to Portuguese, especially with legal documents and localization for the Brazilian market, is outstanding. It gets the subtleties that other tools miss, like nuances of keigo (敬語) or handling of CNPJ for Brazilian context.

Guarantee Perfect Accuracy with a Free Custom Dictionary

You want your key technical and business words translated just right — not just literally. Our Custom Dictionary lets you define Portuguese equivalents to match Brazilian standards.

Brand Integrity

Guarantee all company names or services such as '楽天株式会社' (Rakuten, Inc.) are always translated as 'Rakuten S.A.', never as 'Empresa Rakuten' or other non-standard terms.

Technical Precision

Set precise translations for technical jargon. For example: 'ICタグ' should always be 'etiqueta RFID', and not apenas 'tag IC'.

Brazilian Legal Terms

Ensure concepts like '代表取締役' always become 'Diretor Presidente', not 'Representante Executivo', to match Brazilian corporate titles.

Consistent Phrasing

Keep legal and compliance phrases uniform — e.g., '本契約はブラジル法に準拠します' always as 'Este contrato será regido pelas leis do Brasil'.

Accurate Translations for Every Profession

Don't risk a generic mistake in critical cross-border files. Our AI is bespoke for Japanese-to-Portuguese with real data from legal, tech, and business documents used in Brazil and Japan.

Legal & Corporate

Scenario:

Translating a partnership agreement from a Japanese trading company for operations in São Paulo.

Challenge:

An error translating '取締役会決議' (board resolution) as 'resolução do conselho' (instead of 'Ata de Reunião do Conselho de Administração') could lead to regulatory issues at the Junta Comercial or Receita Federal.

Solution:

Our AI recognizes and adapts to legal structures required by Brazilian Lei das Sociedades Anônimas (Lei 6.404/76), ensuring terminological and cultural compliance.

ContractsCompany BylawsShareholder AgreementsNotarial Deeds

Finance & Investment

Scenario:

Localizing annual financial report of a Japanese company on the Tokyo Stock Exchange for Brazilian investors.

Challenge:

Numeric, currency, and IRPJ/CSLL-related terms must be converted to Brazilian standards. For example, '売上高' should map to 'Receita Bruta', not just 'vendas'.

Solution:

Our AI converts date, number, and financial notation (e.g. ¥1,234 → R$ 52,30) and recognizes Brazilian tax/reporting standards.

Annual ReportsInvestment ProspectusAudit ReportsBank Statements

Technical & Engineering

Scenario:

Translating machinery manuals from a factory in Osaka for installation at an industrial plant in Manaus.

Challenge:

Literal translation of assembly warnings or technical part names (e.g., バルブ: 'válvula') may confuse or risk safety if not in Brazilian standard jargon.

Solution:

Our AI references Brazilian technical norms (ABNT), always picking 'atenção' over 'cuidado' for warnings, guaranteeing usability and compliance.
