Japanese Translator FAQ
What is the most accurate Japanese translator?
This depends on your needs! For simple vocabulary translations or industry-specific terms, for example, it’s best to select a Japanese translator designed for that purpose.
In general, however, DeepL is considered a highly accurate, top-tier translator that excels at everyday sentence-level translations between Japanese and English.
How can I translate Japanese accurately?
Use a mix of machine- and person-based translation.
Once your text has been translated by a translator application, double-check it using your own knowledge of Japanese vocabulary, grammar and politeness rules, as well as context.
Because Japanese to English translations can be difficult for software, if you have the option, it’s always beneficial to ask a native Japanese speaker to confirm machine-based translations.
Bettering your Japanese will require improving the four language skills—reading, writing, listening and speaking. You can do this on your own, with a Japanese tutor or via a language learning program.
