There are both a chapter on sashimi or yuzu a chapter on the bento box or a chapter on a known beer. This is intentional and is an organized mess, with the end of the guide an overview of products by theme (seafood products, tableware, etc.).
For each product there is also Internet links to find more information and references to find the product (often found point in this type of works, and very frustrated that leaves the reader). At the end he even has a list of different stores where you can provide. Attention each subject to the right page and continues on the next page left. Illustrative photos are on the opposite page (thus left page), this can be disturbing at first (it is thought that the photo illustrates the end of the article).
It is a good gift idea for someone you do not know very well but who loves Japan, and which can be left on a table to open the appetite and conversation.
