High school and postsecondary teachers of Japan and Asia will find this book valuable for their teaching. The introductory essay in and of itself is an excellent explanation of the complexities and developments of the 268-year period of early modern Japanese history. Of course, the most important component of the book is the primary documents, and because of the intelligent selection of the 60 documents, Vaporis has made the Tokugawa period more accessible for students.
