How to use English to Japanese Translator
- Paste the English source text in the input field
- Pick formality: Keigo (honorific, business with superiors/customers), Teineigo (standard polite), Casual (friends, social)
- Specify the audience: business client, friend, social media followers, technical staff
- For UI strings, mention character limits — Japanese is often shorter than English (kanji density), so character counts may surprise you
- Generate; for transliterated names, ask "give katakana for the names" or "keep proper nouns in English"
Tips for better results
- Default to keigo for any business correspondence in Japan — overly casual sounds rude even with good intentions
- Foreign names usually go in katakana — ジョン for John — but specify if you want the original Latin spelling kept
- Many tech and product names stay in English in Japanese marketing — verify your brand and product names are handled the way your style guide dictates
Frequently asked questions
What is the difference between keigo, teineigo, and casual?
Keigo: honorific language for superiors and customers. Teineigo: standard polite (most adult conversation). Casual: friends, family, and informal social media. When in doubt for business, use keigo.
Will it handle furigana for difficult kanji?
Ask in your prompt: "include furigana over kanji above JLPT N3 level" — useful for learner content or children's materials. Standard business output does not include furigana.
Can it translate honorifics (san, sama, kun) correctly?
Yes — specify the relationship and context. Customers and clients get -sama in formal writing, business contacts get -san, kids and juniors might get -kun or -chan. Tell the model the relationship.
How does it handle vertical Japanese writing?
It outputs horizontal (left-to-right) text by default. For vertical layout (traditional novels, formal documents), apply CSS writing-mode in your destination — the text content itself is the same.
