These works belong to Bound: A Journey of 600 km, made using the Binding and String technique — copper plates bound with string, etched, and printed. 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 are the five handmade books created during this project, undertaken from 2022 to 2023.
