(C) KADOKAWA/Photographer: Yasutomo Sanpei Since his debut at the age of 17, Koji Seto has steadily built his career as an actor, appearing in numerous dramas, films, and stage productions. To mark the 20th anniversary of his debut in December 2025, he will be releasing a commemorative anniversary book. This book features still photography based on visual themes of Seto Koji’s own devising, such as “The Changing Scenery from Moving to Tokyo to the Present,” “What it Means to Take on the Colors of a Role,” and “Things that Represent Seto Koji.” The book also features beautiful, ageless gravure photos. Additionally, the book will feature illustrations created specifically for the book on the theme of “creation,” which are based on the art he pursues alongside his acting career. In addition to a long interview looking back on the 20th anniversary from various angles, the book also includes conversations with up-and-coming artists and creators with whom the band has long had close ties. This book offers a glimpse into the inner world and expressiveness of Seto Koji today, as he continues his career as an actor. Comment from Koji Seto I’ve been devoting myself to imagining and expressing my ideas for the past 20 years. In this book, I was able to challenge myself to express myself up to this day in various ways. This book will allow readers to take in various images from the photographs, illustrations, and words, and to freely and joyfully imagine their own world. I hope it reaches many people.
