Welcome to White Rabbit Japan!
Unless you are an advanced learner of the Japanese language, reading books and long texts is a very challenging task. Reading a newspaper in Japanese requires knowledge of 2000+ kanji and many words that are not commonly used in everyday life. Graded readers on the other hand are made for people just like you: Beginner and intermediate Japanese learners. Nihongo Tadoku Books Vol. 3 is aimed at intermediate students at around the N3 level and lets you have a sense of achievement for being able to read a book in Japanese without too much trouble. Vol. 3 covers level 3 (details explained down below) and includes 7 stories.
