The Self-Esteem Academy (Chairman: Teru Nakashima) announces that in April 2026, the book 'Textbook of Self-Esteem: Becoming Able to Think You Will Be Fine No Matter What' (Author: Teru Nakashima / SB Creative) has been approved for its 32nd printing, surpassing a total of 760,000 copies sold.

Message from the Author, Teru Nakashima

'760,000 people have read it. But the numbers regarding self-esteem in Japan haven't moved. That's why I can't stop yet. Next, it's the children's turn.' (Author: Teru Nakashima)

Why it keeps selling for 7 years

Even now, 7 years after its release in February 2019, this book continues to be reprinted. The reason lies in the 'reverse thinking' that overturns the conventional idea of 'raising self-esteem'. This book advocates an approach that says, 'You don't need to force yourself to raise your self-esteem. The 6 senses will naturally nurture it.'

The '6 senses' derived from author Teru Nakashima's over 30 years of research and clinical experience with over 15,000 people are: Self-worth, self-acceptance, self-efficacy, self-determination, self-usefulness, and self-trust.

By accumulating these from the foundation, it is designed so that self-esteem rises naturally without strain. This practical and highly reproducible method has generated readers' voices saying, 'I actually felt a change,' continuing to expand its support primarily through word of mouth.
