In terms of writing, it's pleasant enough, but the style sometimes was a little disturbed by its oral side too: I do not mind the light, but I did not want to read such phrases that pronounces. There are also a few mistakes here and there (I just opened the book at random and I came across "savory preparations" for example), but this seems to be a habit unfortunately Dunod (I had to test three books by this publisher: three books with mistakes!).
Throughout the book, you discover many stories and information on Japan, and the single page dedicated to each "flavor" sometimes seems too small to contain everything. It is therefore not at all bored by browsing the book, but it is not like reading a novel, from one end to the other, but leafing according to our desires or dishes that make us envy.
You do not find recipes, this is not its purpose. But the descriptions you have under the eyes will make you want to search the Internet or in books specifically on Japanese cuisine. It only remains to be hoped that an Asian grocery store is near you, otherwise it will be the certain frustration
