President's Handbook, Set of 2 Books by Mitsuru Sato Each 1300 yen (excluding tax) Set of 2 This book cultivates a business mindset and perspective based on the "Magic Number Three Law," which is said to be composed of three well-balanced elements. For example, there is an explanation of the three spirits of the Omi merchants, and the author's background in the automotive industry shines through in the explanations of Soichiro Honda and Toyota's approach to challenges. While the previous book, "President's Handbook," had the effect of a panacea for life, this book can be said to be a specialized medicine that focuses on the business ailments of business leaders. It is especially recommended for managers and business people who will be promoted to executive positions.
