Idogawa has systematically explored gindei-saiji (silver-painted porcelain), an advanced decorative technique in traditional ceramics in which precious metal powders, overglaze pigments, porcelain bodies, firing conditions, and other elements interact in complex ways. He approaches this technique through both research and the creation of his works.

As a result, he has received numerous honors at Japan’s most prestigious public and craft exhibitions, including the Takamatsunomiya Memorial Award at the 62nd Japan Traditional Art Crafts Exhibition, and is contributing to new developments in the craft field.

He has also produced original works inspired by everyday vegetables such as daikon radish sprouts, chili peppers, and broccoli, revealing familiar beauty from new perspectives.

At Hiroshima University, he has dedicated himself to cultivating the next generation through craft and formative arts education, mentoring many students. His achievements in research, education, and social contribution together reflect the significance of this award.

“I still cannot quite believe it, but when I look at the remarkable ceramic artists who have received this honor before me, I feel truly honored. I would like to express my gratitude to everyone associated with Hiroshima University and its faculty and staff,” said Idogawa.
