『2021 Latest Revised Edition JLPT (Japanese Language Proficiency Test) N4 in One Book』 is the fifth revised edition of the 『Complete Japanese Language Proficiency Test in One Book Series』, which was first published in 1998 and has been greatly loved by Japanese language learners for over 20 years.


To ensure that learners can fully prepare for the exam, the course is structured in the same format as the actual exam questions: 1st period language knowledge (characters, vocabulary, grammar) and reading, and 2nd period listening.
Based on Darakwon's accumulated big data, we've compiled the vocabulary and grammar from the JLPT revisions from 2010 to 2021 into an easy-to-read format. We've also included review questions that thoroughly analyze the question types, allowing you to comprehensively master each section of the test: vocabulary, grammar, reading, and listening comprehension.
Additionally, in this revised edition, the interpretation and commentary booklet has been separated into a separate volume to make it easier to solve and check problems, thereby increasing the convenience for learners.


To help you achieve a high score on the JLPT N4, we provide four mock tests (two in a separate booklet and two online) that you can practice for just like the actual exam right before the exam, as well as the Speed ​​Check Book, an essential item for the exam.
You can download online practice tests (PDF), vocabulary worksheets (PDF), and listening audio files (MP3) from the Darakwon website and use them for your studies.
The audio files for listening comprehension can be listened to or downloaded directly on your smartphone.
