Kanjily: Learn Japanese & JLPT · Effective October 19, 2026

Kanjily works offline with open data. Thank you to the communities that make it possible.

Dictionary and kanji: EDRDG (JMdict, KANJIDIC2, KRADFILE/RADKFILE)

This app uses the JMdict, KANJIDIC2 and KRADFILE/RADKFILE files. These files are the property of the Electronic Dictionary Research and Development Group (EDRDG), and are used in conformance with the Group's licence, the Creative Commons Attribution-ShareAlike Licence (V4.0, CC BY-SA 4.0). JMdict was compiled by Jim Breen and many contributors; KANJIDIC2 by Jim Breen; KRADFILE/RADKFILE by Jim Breen and the Kanji Dictionary Group.

The dictionary database used by Kanjily was modified from the originals and is shared under CC BY-SA 4.0. Changes we made:

the data was converted to an SQLite database (with a full-text search index);
romaji and search forms were added;
furigana, pitch accent and level information from the sources below were attached;
entries were linked to kanji data and example sentences.
