Mizukara Inc. (Headquarters: Chiyoda-ku, Tokyo; CEO: Kentaro Yamamiya), which provides coaching based on cognitive science to corporations and individuals, is pleased to announce that the cumulative number of copies of the book 'How to Change Yourself: Going to Meet a New You Through Cognitive Science Coaching' (published by Gentosha) written by Director and CPO Daiki Muraoka has surpassed 50,000 copies approximately one year after its release.

A Practical Guide for Those Who 'Want to Change but Cannot'

'How to Change Yourself' is a book that squarely addresses the question of 'why people cannot change' based on insights from cognitive science and neuroscience, systematizing the mechanisms and concrete processes of change.

Immediately after pre-orders began in March 2025, it secured the No. 1 spot in seven categories, including Amazon's 'Books Overall' ranking, garnering a huge response even before its release. Since then, it has expanded its readership primarily through word-of-mouth, gaining support from a wide range of demographics including business professionals, students, and executives, and has now surpassed 50,000 cumulative copies sold.

Features of the Book 'How to Change Yourself'

This book is not merely self-help; it applies the latest findings in cognitive science to provide concrete steps for readers to proactively transform their own lives. The main features are as follows:

A Method to 'Change Yourself' Utilizing Insights from Cognitive Science Coaching
• It elucidates the unconscious mechanisms that govern human behavior, encouraging readers to understand their own thought patterns.
• Through specific exercises, it promotes practical behavioral changes rather than just theory, supporting sustainable transformation.

A New Approach Focusing 'Outside the Current Way of Living'
• It advocates a unique way of thinking where goals are set by working backward from an ideal future, rather than as an extension of the present.
• It specifically explains how to increase the efficacy (self-efficacy) necessary to achieve goals, building a foundation for readers to take on challenges with confidence.

Practical Advice Based on Over 5,000 Coaching Experiences
• It includes insights gained by the author, Daiki Muraoka, through coaching over 5,000 individuals, alongside abundant case studies of clients who have actually 'changed their lives.'
• By introducing success patterns based on scientific evidence, it guides readers to find the optimal approach suited to their own situations.

Special Campaign Launched to Commemorate the 1st Anniversary & Exceeding 50,000 Copies

To commemorate the 1st anniversary of the book's release and its surpassing of 50,000 cumulative copies, a limited-time special campaign will be held for 'REBOOST,' the experiential self-understanding program provided by Mizukara.

We will apply a record-high discount of 50,000 JPY to provide the 'experience of changing oneself' to as many people as possible.
