The easiest way to learn Japanese from games

A full toolkit for extracting text from videogames, looking up words, translating, creating flashcards, and more.

Combines all sorts of functionality for an all-in-one experience

OCR, dictionary, translation and more, all in a single window.

High-accuracy OCR

Thanks to Google Cloud Vision technology, Kamui features 99% accuracy Japanese text OCR. Think like Google Lens, but way more convenient to use. Even blurry and pixelated kanji don't stand a chance.

Windows app with Auto-OCR EXPERIMENTAL

Download Kamui Desktop (Windows-only) for greater ease of use, including fully automatic OCR and hotkey use from anywhere!

Text analysis

Scanned text is automatically separated into words, so you can easily tell what's what and more quickly look up the stuff you need.

Integrated dictionary

Convenient dictionary sidebar to perform lookups from the words found in the text. Just click a word and its definitions will come up. Context-aware lookup based on text analysis makes sure you get only the most relevant definitions.

Anki support

Just click the Anki button on a dictionary entry to add it to Anki. You can either configure a deck of your own, or use the no-hassle Kamui deck.

AI-powered auto translation

Immediately get translations for all scanned text. Useful for making sense of hard sentences, or simply if you want to play untranslated games without learning Japanese. GPT-4 available!
