Most books in Japan would have been a collaboration between several people, all contributing to a different aspect of the book: the author to write the story, an artist to paint or cut and print the wood-blocks, paper makers, and book binders.
In addition to these pictures, supplementary materials would be included, although they might not be directly related to the images. Typically, Japanese books would involve a team effort, with multiple contributors working on different sections: an author crafting the story, an artist creating the wood-block prints, paper manufacturers producing the paper, and book craftsmen assembling the finished product.
