Frequently Asked Questions

Is this Japanese translator free?

Yes! Our Japanese translator is completely free to use with no registration required. Translate as much text as you need.

How accurate is the translation?

Our translator uses Google Cloud Translation API, one of the most accurate machine translation services available. While no machine translation is perfect, it provides high-quality translations for most everyday use cases.

What is romanization (romaji)?

Romanization, or romaji, is the representation of Japanese text using the Latin alphabet. It helps non-Japanese speakers read and pronounce Japanese words. Our translator automatically provides romanization for Japanese text.

Is my translation history saved?

Yes, your translation history is saved locally in your browser. This means your translations are private and only accessible on your device. You can clear your history at any time.

What is the maximum text length?

You can translate up to 5,000 characters at a time. For longer texts, we recommend breaking them into smaller sections.

Are there usage limits?

Yes. We apply fair-use rate limits during high demand to keep the translator reliable for everyone.

Accuracy and limitations

Machine translation may miss nuance in humor, slang, honorifics, and context-heavy writing.
Names, dialects, and anime-style expressions can have multiple valid readings.
For important content, compare alternatives and verify key terms with kana/kanji study tools.
Best practice: split long paragraphs into shorter sentences for cleaner results.
