The Kodansha Kanji Learner's Dictionary is a kanji dictionary based on the New Japanese-English Character Dictionary by Jack Halpern at the CJK Dictionary Institute and published by Kenkyūsha. Originally published in 1999 (with a minor update in 2001), a Revised and Updated Edition was issued on 2013, reflecting the new changes in the jōyō kanji mandated in 2010. This Revised and Expanded Edition increases the number of kanji entries from 2,230 to 3,002, as well as changing all pronunciations from romaji to kana. In 2021, a second edition of the Revised and Expanded edition was published, taking into account an increase in the number of jōyō kanji which had occurred earlier in 2020, while also providing relevant compound words. There also exist electronic forms of this dictionary for both iOS and Android. A more extensive version of this dictionary by the CJK Dictionary Institute is also published by Kodansha called The Kodansha Kanji Dictionary.
The dictionary arranges entries according to an original system called SKIP (System of Kanji Indexing by Patterns). The dictionary also has indexing by radical and character readings.
