English to Japanese Translation for Novels, Games and Long Documents
Translating a whole novel, a web novel series or thousands of lines of game script into Japanese is very different from translating a single page. Ordinary tools lose track of names, spell the same character in katakana three different ways and drift between polite and casual speech from one chapter to the next. They also get honorifics wrong, so a respectful -san can turn into a familiar -kun, and line breaks or punctuation can come out messy.
Our bulk translation service uses AI built for long texts, so your story or document is handled as one connected work rather than as scattered fragments. You control a glossary of names, terms and honorifics so they stay consistent from start to finish, and a final editing pass reviews the result.

What it is, which languages, roughly how long, and when you need it. A short sample helps us quote accurately.
Get a quote
We reply by email with a price and any questions. Nothing is charged until you agree.
Agree the names and terms
Characters, places and special terms go into a glossary you can check, so every chapter uses the same spelling.
Receive it in batches or all at once
Every section is translated with the whole chapter in view, then a final editing pass checks for anything missed.
Why use us for large jobs
Consistent from start to finish
A glossary of names and terms is applied to every chapter, so a character never changes name halfway through a book.
Context, not sentence by sentence
Each section is translated with the whole chapter in view, so meaning, tone and voice carry across.
Checked before delivery
A final editing pass and automatic checks look for missed lines, slips between sections and inconsistent spellings.
Fast at any size
Hundreds of chapters are no harder for us than one, so large projects don't take months.

Questions
How do you keep character names consistent in katakana?
You decide. In your glossary you set exactly how each name should be written, for example whether Catherine becomes キャサリン or カトリーヌ, and which honorific a character uses for others. Those choices are applied throughout the whole text.
English has no politeness levels. How is tone handled in Japanese?
Japanese has to choose between formal and casual speech and between first-person pronouns like watashi, boku and ore, which English rarely signals. Our AI reads long stretches of context to keep each character's voice steady, you can add notes on speech style to your glossary, and a final editing pass reviews the translation.
