Kaku1.3.78

Kaku recognizes kanji directly from the Android device screen and turns them into dictionary lookups, so Japanese learners can study text without manually searching for each character. Its optical character recognition (OCR) is designed for reading manga, playing untranslated games, and working with other screen-based Japanese content. The result is a focused way to connect language study with authentic Japanese encountered in everyday digital media.

The app places its dictionary interface above other apps, allowing users to inspect recognized characters while the original material remains visible. This suits learners who build study sessions around raw manga, games, and other Japanese media rather than a general entertainment experience. Kaku is aimed at people who want a practical Japanese-reading workflow centered on kanji encountered in context.

Kaku is open-source Productivity software for Android, with version 1.3.78 requiring Android 5.0 or later. It supports arm64-v8a, armeabi-v7a, x86_64, and x86 devices. Its screen-reading approach provides an Android counterpart to the kind of OCR dictionary workflow associated with KanjiTomo and browser lookup extensions such as Rikaikun, Rikaisama, and Yomichan.
