Best kanji dictionary app there is!

No other kanji dictionary app even comes close to comparing to this one. The core meanings and SKIP is incredible!

Indispensable for Any Student of Japanese

This is a must have resource for students of Japanese. As a book it is superb but in its electronic iteration it is truly an indispensable item. No true grasp of the Japanese language is possible without knowledge of Kanji, and no significant Japanese vocabulary can be attained without knowing and understanding Kanji. In this resource, multiple Kanji can be cross-referenced and rapidly studied (including close ups and stroke order animations) with a simple tap on a character...this includes component characters in all vocabulary examples which follow each of the the main character listings. The speed and utility of a digital format facilitates quick understanding of word formation. It is so quick that I actually have fun using it. The breadth of vocabulary one can attain even with occasional study using this dictionary is astonishing and there literally is no finer English language reference. That Kodansha published this dictionary is a testament to its quality. It may cost a bit more but it is well worth it! I am a long time student of Japanese and have tried all of the other dictionary and Kanji mnemonic memorization tomes but always return to this one for its thorough and comprehensive treatment of the Kanji.

Tremendous Tool and Study Aid

An impeccable implementation of the original book by Jack Halpern and the CJK Institute, I highly recommend this app for all serious students of Japanese Kanji. I had used the book for many years and found it to be the most complete single-source document for studying Kanji. Its expose’ of each character in various compound usages by meaning greatly contrasts the limited content found in other study materials. In book form, the SKIP classification system allowed me to locate nearly any character in less than 20 seconds! Now as an app, it’s even easier and quicker. A truly outstanding contribution to kanji studies for newcomers and academics, alike.
