The title does not speak to "learn" and that's probably what there is more accurate; there is no question of a method and there is little to learn in the sense of a systematic and steady progress. This is actually a popular book or sense distraction offer a first approach to Japanese writing, a discovery of the level of the sixth as there could be to Egyptian hieroglyphics. If you are hardworking you can probably "impress your friends" as a chapter suggests. Errors, inaccuracies and fantasies. Thus we learn that the Chinese script arrived Japan in the middle (so be precise) of the sixth century BC! The mnemonic means is proposed to retain some character, actually really little because it's mostly up to you to build you the stories that allow you to retain a sense of character. we give you some examples, imprecise. Besides the description on the internet talking about 800 characters and the introduction of the book of only 150 and this should certainly include the kana syllabary! The book mixes all genres: fragments of explanations on the original meaning of the key components or characters, with whimsical mnemonic associations inapplicable to the same element used in another character; bits of Japanese grammar elements syllabary and ideograms and syllabary again, small writing vocabulary useful travel ... in short a hodgepodge of little use.
The book is the pocket-sized type, a little larger, soft cover and yellowish paper, printing in black and white, line spacing and margins minimized, printed characters really small (not easy to remember when we not see the detail) , ungainly designs ...
I do not recommend it except for a schoolboy who should make a presentation on Japanese writing ...
