Whether you plan to take the JLPT or not, learning advanced Japanese Kanji will help you read Japanese newspapers, novels, and essays, and make real headway in understanding written Japanese.
Try this fun, free Japanese Kanji quiz, and see if you know the correct readings. For the ultimate challenge, leave the furigana (hiragana above the Kanji) off, and see if you can read all the sentences unaided. Then, turn on the furigana to check your readings.
Nihongo-Pro teachers and staff wish you the best of luck on the JLPT N1 and in all of your Japanese study endeavors.
