Entertaining and great for those of us in the not-so-advanced stages of learning Japanese. I found having the audio read at normal and slow speed very helpful. I could listen on slow and catch things I wasn't as familiar with for further study and then on normal to check my comprehension after studying.
An interesting story is written in kanji but with furigana makes it easier to read for us who are not familiar with many kanji. The vocabulary is nicely made by words from story and grammar form explanations. I like the most the all-Japanese part story, without vocabulary on the bottom of the page where I can test my knowledge.
The audio materials are a very good way to become friendy with the way Japanese is spoken and the fact that the book contains a few audio version, leveled by speed, is just awesome.
I love how there are different forms of listening to a Japanese story, since that truly helps to break down the words and to learn some of the vocabulary! Also, I enjoy the voices for the audio in Japanese and English, both sound beautiful.
