Katsumi Komagata (Shizuoka, Japan, 1953). Following a stint at Nippon Design Center, Inc., he moved to the United States in 1977, where he worked as a graphic designer. He returned to Japan in 1983 and three years later founded One Stroke, which began as a graphic design studio and later expanded into publishing.
The birth of a daughter prompted him to take up picture-book authoring and he is now world-renowned for his exquisitely crafted books. He has also created picture books for children with disabilities, including tactile and sign-language books.
He has held shows and workshops around the world, and won numerous honors, including an ADC Silver Cube (New York), the Prize for Creativity (Paris), a New Art Prize as well as a BolognaRagazzi Award Mention at the Bologna Children's Book Fair, an International Children's Book Award (Switzerland), and two Good Design Awards (Japan).
