For Japanese–French translation, specify the direction, reader and target market before requesting prices. Japanese source characters and French source words are different billing units. Compare a complete quote for the same document, including minimum charges, subject expertise, review and formatting.
Match the process to the purpose
Use | Specify | Acceptance focus |
|---|---|---|
Internal understanding | Reader, relevant sections and field | Meaning, numbers and terminology |
Website or product copy | Market, audience, style and brand voice | Natural wording, claims, prices and conditions |
Legal or technical material | Purpose, glossary and specialist reviewer | Definitions, source correspondence and omissions |
Official submission | Receiving institution’s format, translator and certification rules | Compliance with that institution’s requirements |
State whether the audience is in France, French-speaking Canada or another market. Discuss vocabulary and presentation requirements. “Native review” alone does not define a quality process: translation, comparison with the source, target-language proofreading and specialist review are distinct activities.
Read published prices in context
The following Japan-based provider examples were checked on September 30, 2026. Amounts are JPY excluding tax; scopes differ, so this is not a market average or a price ranking.
Provider | Japanese to French | French to Japanese | Conditions |
|---|---|---|---|
Standard: from ¥17 per source character | Standard: from ¥17 per source word | ¥20,000 minimum; complexity, timing and layout affect price | |
Technical translation: from ¥12 per source character at difficulty C | Request a quote for the same source document | B starts at ¥17 and A at ¥19 per source character; confirm classification and extras |
An identical headline rate of ¥17 in both directions does not imply an identical price for equivalent content. Do not assume translation into Japanese is always cheaper. Check extraction from scans, tables, revisions, certification and rush fees.
A total-cost comparison
This hypothetical example is unrelated to the providers above. Assume 800 Japanese source characters translated into French with the same deadline, review scope and output format.
Item | Quote A | Quote B |
|---|---|---|
Base calculation | 800 × ¥18 = ¥14,400 | 800 × ¥25 = ¥20,000 |
After minimum | ¥22,000 | ¥20,000 |
Layout | Add ¥2,000 | Included |
Total before tax | ¥24,000 | ¥20,000 |
A has a lower unit rate but a higher total. If one quote includes a necessary specialist check and the other does not, align that scope before choosing. Agree how source revisions or additions change the quote and who approves extra work.

Check certification and confidentiality before commissioning
An institution may require particular translator credentials or authentication procedures. A provider’s translation certificate is not automatically accepted everywhere. Obtain the receiving institution’s current requirements first and confirm the provider can meet them.
For confidential documents, agree sharing and confidentiality before transmission. Ask about subcontractors, external AI, training use, storage, deletion and the extent of human checking. Choose the process for the document’s purpose and the consequences of errors.
Acceptance checklist
- Compare names, dates, quantities, currencies, units and reference numbers with the source.
- Check technical and product terminology against the approved glossary.
- Look for missing headings, tables, notes and links.
- Review accents, punctuation and line breaks in the actual publication format.
- Consolidate questions, request corrections and retain the approved final version.
