It is a niche hobby and the petite nature of these miniatures is indeed a true test of being detailed. The accomplished works in the book are adorable and realistic.
The book is only available in Japanese. Sadly, I could not locate any English version of the book. Here is a look at the content page.
The content is structured similarly to a recipe book with a list of ingredients and materials needed and followed by a step-by-step guide that are displayed in pictorial format.
This section of book is the additional instructions on how to create the other materials used in the recipe.
The book provides a wonderful source of inspiration at the price of NT389.00 (RM44.20).
