"My child has no motivation?" Actually, "Brain Fatigue" was the cause! Naoko Narita's new book "Child Brain Fatigue" released April 28th.

Nihon Bungeisha Co., Ltd. (Chiyoda-ku, Tokyo) will release 'Child Brain Fatigue' by Naoko Narita at bookstores and online retailers nationwide starting Tuesday, April 28, 2026.

What are the signs of 'Child Brain Fatigue' that cause irritability and lack of focus, and how can we let them rest?

The idea that 'children are always energetic' is no longer true!? Irritability, lethargy, and loss of concentration are caused by 'Child Brain Fatigue'!

Many parents worry: "My child lacks concentration," or "Is their lack of stamina why they shut down so quickly?" However, the cause is neither personality nor a matter of motivation. In fact, it may be related to the child's "brain fatigue."

Modern children have super hard schedules! Invisible fatigue is piling up. In the past, the common belief was that 'children are always energetic.' However, modern children face daily invisible burdens such as increased information, lack of sleep due to busy schedules, and over-parenting. Even if they look healthy, their brains may not be resting enough... That state is 'Child Brain Fatigue.'

A child's brain has a three-layer structure: "body," "heart," and "thought." This book provides hints to adjust the "physical brain," which serves as the foundation, without strain.

In this book, an expert who has long researched children's brains and development clearly explains why modern children tire easily and what happens to their actions and emotions when their brains are fatigued. Furthermore, it introduces ways to organize the home environment and how to interact with children to draw out their inherent resilience. Instead of forcing them to work harder, allowing the brain to rest encourages children to move on their own. This book is packed with such hints.

Toward parenting that doesn't push too hard. To prevent child brain fatigue from accumulating, we suggest what parents should "stop doing" and the "perfect distance" to maintain.
