[Machine Translation] Muneyoshi Yanagi's "Forty Years of Folk Art" has long been popular as a standard introductory book on folk art. However, Yanagi had a plan to revise and improve this famous book. This book is a compilation of 15 essays that Yanagi added to the table of contents of the first edition of "Forty Years of Mingei" during his lifetime, newly supplementing them and reflecting his correction instructions. This edition has been edited to reflect Yanagi's correction instructions and to clarify Yanagi's message through "Mingei". How can we grasp the true beauty of things? What makes things beautiful? What does it mean that the principle that makes things beautiful also applies to the salvation of lost human beings? The answers to all of these questions are in this book.
