reconstructing marketing as a system rather than a feeling. Author Tatsuo Koyama systematically explains everything from attracting customers to differentiation, branding, systematization, and copywriting, drawing on the success principles he has cultivated through his work on YouTube and in corporate consulting. Rather than relying on numbers or theory, we delve deeply into human psychology to understand “why people act” and “how they can be chosen.” We present “reproducible marketing” that can be applied to businesses of any industry or scale. In addition, based on the know-how shared on the author’s YouTube channel, “Marketing Samurai’s Unconventional Business Theory,” which has over 100,000 subscribers, and theories honed through supporting numerous companies, this book is designed to help even beginners achieve a “change in thinking that leads to results in just one day.” In addition, it includes concrete strategies you can start putting into practice today, such as 28 copy examples and how to use social media and YouTube. This is a new marketing bible that will change the way you think in just one day, for everyone from beginners to business owners. ■Book features The greatest feature of this book is that it systematizes marketing not simply as a “customer
acquisition technique,” but as a “scientific skill” based on human psychology and structural design. This book is designed to be applicable to all businesses, from sole proprietorships to large corporations, and emphasizes “practice that produces immediate results” over theory. Customer Attraction First: The origin of marketing is not “selling” but “attracting” The Essence of
Differentiation and Branding: How to Create a Strategic Position that Generates Unique Value Reproducibility through systemization: How to create hits by “design,” not “chance” Psychology and copywriting techniques: The power of words and design to move people’s hearts Utilizing social media and YouTube: The secret to building customer acquisition channels that are in line with the times ■Author: Tatsuo Koyama (Koyama Tatsuo) Profile Born in Kagawa Prefecture in 1982.
