KADOKAWA Corporation announced the release of 'The Power to Choose to Be Alone from Age 15,' the debut book by Takaya Mizuno, operator of the educational YouTube channel 'Yambaru Zemi,' on Thursday, May 21, 2026.
Career choices for teenagers are significant decisions that influence the rest of their lives. While university enrollment rates exceeded 58% in fiscal 2025, with many aiming for employment at large corporations, the emergence of generative AI and shifts in traditional hiring mechanisms are making these choices increasingly complex.
This book is the first by Takaya Mizuno, who manages the 'Yambaru Zemi' YouTube channel with over 750,000 subscribers. Drawing on his five years of experience as a public middle school teacher and his ongoing work counseling teenagers, the author selected 27 common concerns and compiled them into an accessible dialogue format.
Questions addressed include:
- 'Is there any point in attending a low-tier university?'
- 'What do you think about the feeling that recommendations are unfair?'
- 'How do teachers perceive bullying?'
These are issues students may find difficult to ask teachers directly. The book serves as a collection of essential lessons for high schoolers, middle schoolers, university students, young professionals, teachers, and parents alike.
