I bought this collection approximately 2 months after I started learning Japanese. My knowledge was very low, I barely had learned Hiragana by then and my primary goal was to train my brain's "optical character recognition algorithm". After I borrowed the first volume via Kindle Unlimited, I spontanously decided to buy the complete bundle and I did not regret this purchase.
Most e-books have 2 or 3 stories (volume 7 only has one, but also this is not a typical Japanese folk tale, The Little Match Girl is actually by H. C. Andersen). You'll find each story
a) in Japanese with running gloss, that means every sentence is explained in detail with all vocabulary,
b) in natural Japanese with Kanji and furigana,
c) as e rough English translation.
Most e-books also have an additional Kanji section and a separate list of all used vocabulary too.
The stories are of different levels of difficulty. Most are well suited for intermediate learners (i.e. level A2 in the CEFR or 1/1+ in ACTFL. For beginners, IMO the second volume is the best because it has also the Japanese text in Hiragana with spaces and an additional grammar section.
I think, 16 $ are totally fair for this bundle, especially considering that you'll get lifelong updates. When I bought the bundle there were only 8 books, the 9th has been added later for free.
I find the stories great and easy to follow. When at home I prefer a book so I have purchased The first four books. I listen to the audio at work. I will but the other books at a later time. I highly recommend these in either digital download or paperback!
I purchased this out of interest as I am wanting to get back to studying Japanese. I have only had a quick look through one of the stories, but I'm really enjoying it so far and my vocab has increased already. Waiting for the kids to go for their nap so I can sit down with a hot coffee and read and learn :) Thank you :)
I bought this as an extra resource for my students. Having a solid story already laid out for them will help them study.
I have just started with the contents of this serie, but I think it is really helpful for beginners like me.
