Abstract
"Science is fascinating." A small sense of wonder experienced in childhood can sometimes shape an entire life. Dr. Sumio Hayakawa is a senior assistant professor at Nippon Medical School, where he conducts research and teaches about the mechanisms that protect the human body. In addition to his academic work, Dr. Hayakawa participates in Kodomo Academia, a science outreach program organized by Bunkyo City in Tokyo. There, he introduces children to the excitement of science. Thanks to the kind arrangement of our mentor, Dr. Mamoru Isemura, we had the opportunity to speak with Dr. Hayakawa at Dr. Isemura's residence in Kyodo, Setagaya, Tokyo. He shared his thoughts as a researcher and educator who has loved science since childhood.
