PROFILEWriter and physician.

Kimihiro Yoneyama was born in Kofu, Yamanashi, in 1952. He is a physician, medical doctor, and author specializing in neurology.

After graduating from Tokyo Metropolitan Tachikawa High School, he studied medicine at St. Marianna University School of Medicine. He pursued clinical work and research, primarily in neurology, earned a doctoral degree in medicine, and in 1995 became an associate professor and deputy director of the university's health management division.

He made his book debut in 1992 with University Hospital: Stories of Doctors. Since then, he has written across a wide range of subjects—including medicine, neuroscience, dementia, caregiving, health, life philosophy, and medical mysteries—and has published more than 300 books.

His many bestsellers include 28 Ways to Prevent Forgetfulness and 30 Ways to Rejuvenate Your Brain. The Brain-Rejuvenating Coloring Book series has sold a cumulative 760,000 copies. He has also appeared frequently on television and radio, including NHK programs.

Since 2007, he has practiced community medicine at Yoneyama Clinic. In 2021, Shogakukan Bunko published his first historical novel, Mitori-i Dokuan, which received the Keibundo Historical Fiction Bunko Award. He continues both clinical practice and active writing.
