Translate a quality procedure (SOP) into Japanese

What changes when an SOP goes into Japanese

Japanese quality procedures are usually written in the neutral written style known as de aru (である調), rather than the polite です・ます forms. The keigo expected in business correspondence does not belong in a shop-floor instruction; what matters is one consistent style throughout. A document that switches register from step to step looks careless to a Japanese auditor.

Instructions take a fixed shape. "Record the temperature" typically becomes 温度を記録すること。, the 〜すること ending marking a directive. The delicate point is the strength of obligation, which your SOP almost certainly distinguishes:

• "shall" / "must" → 〜しなければならない or 〜すること;
• "should" → 〜することが望ましい;
• "may" → 〜してもよい.

Japanese has a single plural form: "the batch" and "the batches" both become ロット. If the difference matters (one batch released or all of them), the source sentence needs a word such as "each" or "all", otherwise the information is lost. Quantities use a counter: "three samples" becomes サンプル3個.

The quality vocabulary you should see

Japanese has an established quality terminology, mostly in kanji with a few katakana loanwords. A Japanese reader expects to see:

• nonconformity → 不適合;
• corrective / preventive action → 是正処置 / 予防処置;
• internal audit → 内部監査;
• document control → 文書管理;
• traceability → トレーサビリティ, management review → マネジメントレビュー.

Acronyms need attention. English ones such as GMP, CAPA or OOS are widely used as they are in Japan, but acronyms from another source language (the French "BPF" or German "GMP-Leitfaden" wording, for instance) must land on the form Japanese readers recognise. Manuce does not take glossaries: if an internal code or equipment name must stay unchanged, check it in the free sample and again in the delivered file.

Layout, fonts and numbering

Technical Japanese runs left to right, with no spaces between words and full-width punctuation: 、 for the comma, 。 for the full stop. Figures, units (mg, °C) and procedure references (SOP-QA-012) stay in half-width Latin characters.

Things to watch in your file:

• Line breaks: without spaces, text can wrap between almost any two characters. In the narrow columns of a step table, reread cells where a term is split awkwardly.
• Fonts: if your template forces a Latin-only font, the computer opening the file substitutes a Japanese one. Make sure the document is opened on a machine with Japanese fonts installed.
• Dates: "01/04/2025" is ambiguous to a Japanese reader; 2025年4月1日 or 2025/04/01 removes the doubt.
• Approval block: "Prepared / Checked / Approved" becomes 作成 / 確認 / 承認. The boxes remain those of your template.

What Manuce returns, and what it does not do

Your SOP is handled by Dédale, the engine specialised in technical text. The file comes back in its original format (Word, PDF, PowerPoint, Excel, plain text, Markdown, HTML, RTF or CSV) with its tables, headers, footers and numbering. For a typical procedure of around 3,500 words (14 pages), the translation is delivered within minutes and stays in your client area, which helps when the next revision comes round.

What Manuce does not do:

• it cannot read a scanned PDF, meaning an image with no selectable text;
• it does not produce sworn or certified translations: if a body requires a translation certified by a sworn translator, you will need another route;
• it does not check whether your procedure meets Japanese regulatory requirements: it translates what is written.

Preparing the file and checking the result

Start from the cleanest source available, ideally the master Word file rather than an exported PDF. If all you have is a scan, run it through character recognition software first.

To make the most of the free sample, check in the translated paragraph:

1. that the style is uniform (である調 or です・ます, not both);
2. that "must" and "may" remain distinct;
3. that key terms (nonconformity, batch release) match the expected vocabulary.

After delivery, have someone who reads Japanese review it, ideally from the receiving site's quality team, with three checks: table cells, the revision history (改訂履歴), and cross-references between sections, which must point to the same numbers as in the source.

In practice

1. Export the master version of the SOP (Word preferably, or a PDF with selectable text).
2. Upload it, choose Japanese and a level: the quote appears at once, based on the exact word count.
3. Read the free sample: instruction style, strength of obligations, quality terms.
4. Pay, then download the Japanese SOP in its original format.
5. Have a Japanese reader check tables, approval block, revision history and cross-references.
