These five handmade books were made using the Binding and String technique — copper plates bound with string, etched, and printed — as part of Bound: A Journey of 600 km. The process continued until the total length of string reached approximately 600 km, symbolising the distance between the studio and the exhibition venue in Fuji City. Presented not as traditional books but as drawings, they formed part of this project, undertaken from 2022 to 2023.
