Fumitake Koga

Fumitake Koga was born in 1973 in Japan. He built his career as a professional writer and ghostwriter, working primarily in nonfiction for general audiences — a discipline that sharpened his ability to take complex ideas and render them in prose that non-specialists could follow and use. His ghostwriting work won the Business Book of the Year award in Japan, establishing him as one of the country’s leading writers in the genre.

In the late 2000s, Koga encountered the work of philosopher Ichiro Kishimi, who had spent thirty years translating and writing about Alfred Adler’s individual psychology. Koga recognized the gap: Adler had ideas that were arguably more practical and less deterministic than Freud or Jung, yet they were inaccessible to general readers. Kishimi had the scholarship; Koga had the craft. Their collaboration was a straightforward division of roles — Kishimi supplied the philosophical depth, Koga structured the presentation.

The result was Kirawareru Yuuki (嫌われる勇気, “The Courage to Be Disliked”), published in Japan in 2013. The book sold over three million copies domestically and was translated into more than forty languages. Koga’s contribution was the dialogue format itself — staging Adler’s ideas as a Socratic conversation between a skeptical Youth and a patient Philosopher, so the reader’s own resistance to the ideas would be voiced and answered within the text rather than left to fester. This structural choice turned a philosophy book into a readable argument.

A sequel, The Courage to Be Happy, followed in 2016 with the same format and similar commercial success. Both books have been published in English by Atria Books/Simon & Schuster. Koga continues to write and collaborate on nonfiction projects in Japan.
