This book is definitely a good book (or even great when used with ease), but its presentation is disconcerting compared to hahituels works, knowledge of furigana is necessary but beyond its presentation this grammar book is actually very good both as idiomatic and grammatical level of interest to students and others to acquire the japonais.De this, but it is a lot of quality out "books" of or Japanese for real, fake, he beginners addresses an audience already practicing the study of a certain Japanese niveau.Bref, apart from its somewhat unusual presentation this book stand out from the usual and dilettantism.
