What does it truly mean to have “Kakugo” in shaping your future?
This book explores a new philosophy of leadership—crafted through a dialogue with AI.

IBM, Oracle, Apple Japan—
Kenji Yamamoto has led some of the world’s top global companies as president.
At the heart of every decision he made was one powerful force: Kakugo—a deep personal resolve.

This groundbreaking book offers a profound reflection on life and leadership, structured around Yamamoto’s original philosophy: “Kakugo 108®”.
But there’s a twist—his conversation partner is not a human, but an AI assistant named Sam.
Together, they co-author a unique dialogue between human wisdom and artificial intelligence.

Through their exchange, Yamamoto shares personal stories of early failures and bold challenges, moments of loss and renewal, and the mindset behind tough decisions.
He speaks candidly about what it takes to be a real leader in an age where machines are rapidly advancing.
