Ask LuvemBooks about Fumitake Koga
- Where should I start?
- Start with The Courage to Be Disliked, the first collaboration between Ichiro Kishimi and Fumitake Koga and a New York Times bestseller. It lays out the core principles of Adler's psychology — happiness, freedom, and change through taking responsibility for your own choices — and The Courage to Be Happy is explicitly a follow-up that builds on it, so reading it first gives you the foundation. It holds a 4.5/5 reader rating from 188 Amazon ratings.
- What's their writing style?
- Across both reviewed books, Koga and Kishimi use a Socratic dialogue format — a back-and-forth between a youth and a philosopher — to present Alfred Adler's psychology. Rather than lecturing, they let ideas about happiness, freedom, and personal change emerge through argument and questioning. It's an approach that turns dense psychological theory into a conversation readers can follow.
- Books we've reviewed
- We've reviewed 2 books co-authored by Fumitake Koga and Ichiro Kishimi. The Courage to Be Disliked uses a Socratic dialogue to argue that happiness and freedom are available to anyone who stops seeking others' approval — 4.5/5 reader rating from 188 Amazon ratings. The Courage to Be Happy is the follow-up, using the same format to explore Adler's conclusion about "the biggest choice in life" — 4.6/5 reader rating from 3,396 Amazon ratings.
- How do their books compare?
- The Courage to Be Disliked is the foundation: it introduces the core principles of Adlerian psychology — freedom from approval-seeking and full responsibility for your own choices. The Courage to Be Happy is a follow-up that assumes that foundation and pushes into Adler's conclusion about "the biggest choice in life," though it works as a standalone deepening too. Both use the same youth-and-philosopher dialogue, so the choice is really about whether you want the introduction or the extension of the argument.
- What genre do they write?
- Fumitake Koga writes non-fiction, with their bio noting numerous bestselling works of business-related and general non-fiction. On LuvemBooks, both reviewed titles fall under Self-Help & Personal Development, specifically books that present Alfred Adler's psychology to general readers through dialogue.
- What should I read after The Courage to Be Disliked?
- The natural next step is The Courage to Be Happy, the direct follow-up by the same authors. It uses the same Socratic dialogue format to explore Adler's conclusion about "the biggest choice in life" and what genuine happiness means, so it picks up right where the first book's ideas leave off. Those are the 2 books we've reviewed, in that order.
