Paraphrasing Tool for Japanese Speakers
L1-aware grammar, paraphrasing, and translation tuned to the specific transfer patterns Japanese speakers face when writing English — from academic abstracts to business correspondence.
What makes English harder for Japanese speakers?
Japanese and English organize sentences differently enough that fluent Japanese academics still face a predictable set of English issues.
Japanese is SOV with optional subjects, no articles, no obligatory plural marking, and elaborate honorific morphology. English is SVO with obligatory subjects, three-way article distinctions, and a near-flat politeness system. Each of those differences leaves a fingerprint in Japanese-authored English — especially in methods sections, peer-review responses, and business correspondence where conventions are tight.
Articles are the densest error category. Japanese marks specificity through context and demonstratives (この/その/あの), so "We checked result of experiment" feels grammatically complete. Tense slips are the second: Japanese -た tense covers both English simple past and present perfect, so methods narratives drift between forms ("We collect samples and measured pH"). Over-hedging is the third — Japanese formal writing prefers indirectness, which carries over as stacked English modals ("we would like to perhaps suggest").
Diglot's Grammar Checker treats these as Japanese-L1 transfer patterns rather than isolated mistakes. Each correction comes with the contrastive context that makes the pattern easier to anticipate next time.
Top Japanese-to-English transfer patterns Diglot catches
| Pattern | Example error | Corrected |
|---|---|---|
| Article omission before specific nouns | "We checked result of experiment." | "We checked the result of the experiment." |
| Uncountable noun pluralized | "These researches show..." | "This research shows..." |
| Dropped subject in narrative | "Showed that pressure increases with temperature." | "The data showed that pressure increases with temperature." |
| Stacked hedging from politeness | "We would like to perhaps suggest that..." | "We suggest that... (or: The data indicates...)" |
| Comma splice from -te form | "We collected data, we analyzed it, we drew conclusions." | "We collected data, analyzed it, and drew conclusions." |

Frequently asked questions
- Why do Japanese writers face so many article errors in English?
- Japanese has no article system. Specificity is signalled by demonstratives (この/その/あの) or context. English requires a/an/the on almost every noun phrase, so Japanese writers make article decisions much more often than they ever did in their L1. Diglot flags these as Japanese-L1 transfer and explains the rule, so the same patterns get caught faster on the next draft.
- Does Diglot help with Japanese-style hedging in academic English?
- Yes. Japanese formal writing favours indirectness and politeness, which often carries over as stacked English hedges ("would like to," "perhaps," "respectfully," "may possibly" in one claim). English journal style prefers calibrated directness. Diglot detects hedge density and suggests tighter alternatives while preserving genuine epistemic caution.
- Are these checks useful for business writing too, or only academic?
- Both. The same Japanese → English transfer patterns appear in business emails, reports, and proposals — just at lower density than academic writing. Diglot's checker applies across document types; the tool surfaces patterns first and lets the writer decide which to accept based on context.
