Only a few fortunate doctors have had the privilege to read the so-called “Okuda Papers,” which is probably the most comprehensive piece of work ever written about hair transplantation by a single physician. The articles, published in 1939, were written using old kanji (Japanese pictographs) and so are unintelligible in part to modern Japanese medical readers. Because of the outbreak of World War II, this seminal work remained virtually unknown outside Japan. Eventually, the Okuda papers were re-discovered and translated into English in 2004 by Dr. Yoshihiro Imagawa (a retired gynecologist trained in the US, father of the Japanese hair transplant surgeon Kenichiro Imagawa).
The scientific papers of Okuda could have changed the history of hair transplantation. Okuda should be recognized not only as a true innovator but also as a fine example of how a meticulous researcher should work. It is a shame that such outstanding research remained unavailable to most dermatologists, hair surgeons and hair researchers for more than 70 years. We hope that this series of articles included in this web page serves as a belated tribute to the figure of this exceptional scientist, and contributes to the divulgation of his work.
