Yuichiro Katsumoto is an artist and educator based in Saitama, Japan. He experiments with manipulating linear objects such as strings, strips, and springs to display letters and pictures. We humans have created art by writing and painting. It can be said that we have compressed our expressions into two dimensions by lines. He therefore seeks to decompress those lines into physical space, and display kinetic typographies and motion graphics using linear objects. He trained in video production, physical computing, and design thinking at Keio University SFC. He received a Ph.D. in 2010 and worked as a researcher at the National University of Singapore. He returned to Japan in 2018 and has been teaching design and practicing art at Tokyo Denki University since 2019.
