Translating Japanese to English: what to know

Subject Omission is Standard

Japanese frequently omits subjects when context makes them clear, while English requires explicit subjects. A sentence like "行きました" (ikimashita) means "went" but English needs "I went," "he went," or "they went." Always determine the implied subject from context—conversation flow, topic markers (は/wa), or prior sentences—and state it explicitly in English to avoid ambiguity.

Politeness Levels Don't Transfer Directly

Japanese has grammatical politeness levels (plain, polite ます/masu, honorific, humble) built into verb forms and vocabulary. English conveys politeness through word choice, tone, and phrasing rather than grammar. Don't over-formalize: です/ます forms usually translate to normal English, not stiff or archaic language. Reserve "sir/madam" or formal constructions only for explicitly honorific expressions like 参ります (mairimasu) or いらっしゃる (irassharu).

Particle Functions Need Restructuring

Japanese particles (は, が, を, に, で, etc.) mark grammatical relationships but don't translate word-for-word. The topic marker は often becomes the subject in English, but not always. を marks direct objects that may need repositioning. Time expressions with に don't always need "at/on/in." Focus on natural English sentence structure rather than preserving Japanese word order or trying to translate each particle individually.

Context Decides Who Did What — Review Names and Referents

Japanese routinely leaves out not just subjects but objects and possessives when context makes them clear to a human reader ('確認しました' could be 'I checked it', 'we checked them', or 'she confirmed it'). A translator has to guess the missing referents, and on short business messages it can guess wrong. After translating, check that the English names the right person and thing — especially who is doing the action in requests and apologies — rather than assuming the machine recovered the context.

What does the confidence band under the translation mean?

After each translation, a second AI check compares the original and the translation and shows a confidence band: High confidence, Review changes, or Meaning may have changed. It's a model estimate, not a guarantee — whatever the band says, double-check names, numbers and negations in the translation. The raw judge score appears as secondary detail in the “Why?” explanation, labeled as an estimate. The check processes your text and immediately discards it; only the score is kept.
