One language pair, done properly. We focus on the text that decides whether Japanese users stay or leave.
ゲーム・アプリ
UI strings, items and skills, dialogue, tutorials, store pages and patch notes. One glossary keeps names consistent from launch through every update.
ソフトウェア
Interface strings, help articles, onboarding and billing emails, and landing pages, worked directly in JSON, YAML, PO, XLIFF, CSV or spreadsheets.
オンラインストア
Product pages, size guides, shipping and return policies, and marketplace listings in the polite, precise tone Japanese shoppers expect.
For the places your users actually meet the Japanese: on video, and on screen inside your product.
字幕
Trailers, tutorials, online courses and YouTube videos. Send your English captions (SRT or VTT) and get Japanese captions back on the same timing, ready to upload. Every line is checked for reading speed, and names stay the same from episode to episode.
実機確認
We play your game or use your app in Japanese, the way your users will, and report what goes wrong on screen: cut-off or overflowing text, broken line breaks, characters that fail to display, and lines that make no sense in context. Every issue comes with a screenshot, where to find it and a suggested fix.
Translation is priced per English source word, subtitles per minute of video, and LQA per hour up to a cap you approve. Every price is confirmed in writing before we start.
| Service | What you get |
|---|---|
| Edited machine translation | Machine translation, then a native Japanese linguist edits every sentence and a second person checks numbers, terms and anything left out. |
| Human translation | Translated by a native Japanese translator and reviewed by a second linguist. Best for marketing copy, dialogue and anything customer-facing. |
| Japanese subtitles | Translated on your timing by a native Japanese translator and checked by a second linguist. Priced per minute of video. |
| Japanese LQA | Testing on your build by a native Japanese linguist, with a screenshot and a suggested fix for every issue. Priced per hour, never above the cap you approve. |
| Rush delivery | Delivery in roughly half the usual time, for 30% extra. |

Good Japanese is not a word-for-word copy of the English. Here is what we change, and why.
Four things we hold to on every project.
Every project is handled by native Japanese linguists based in Japan, so the Japanese follows how people write today.
One person translates or edits, a different person checks, subtitles included. Nothing ships after a single pass.
A written scope, a fixed delivery date and a price agreed before we start. Read our terms of service before you order.
Files, videos and builds are used only for your project and deleted 30 days after delivery. We sign your NDA on request.
If yours is not here, email us.
Yes. We translate up to 300 words of your own content for a small fee, which we deduct from your first order.
JSON, YAML, PO, XLIFF, CSV, XLSX, DOCX, Markdown and HTML, plus SRT and VTT for subtitles. If yours is not listed, send a sample and we will check.
As a guide, about 5,000 words in 5 business days for edited machine translation, and about 2,000 words in 3 business days for human translation. Rush delivery costs 30% extra.
A build or test link, any keys or test accounts, and the platforms and parts of the product to cover. We report issues in your tracker or in a spreadsheet. Fixing them is up to your team, and we re-check the fixes on request.
For edited machine translation, yes: a machine translation is the starting point and a native linguist edits every sentence. Human translation and subtitle translation are done by a person from the start. Our AI tools are set not to use your content for training.
By card (Stripe) or bank transfer, in the currency of your quote: 50% before we start, 50% within 14 days of delivery.
