"Developmental Trauma: The Real Cause of "Ikizurasa"(Japanese term meaning "chronic distress" or "difficulty in living") (Discover Twenty One, 2023)

 
[Amazon Japan] [Publisher page]
 

Introduction

The book begins with the rising recognition of developmental trauma in Japan, especially after the news that Princess Mako was diagnosed with complex PTSD. The introduction distinguishes between PTSD, complex PTSD, and developmental trauma, and explains why developmental trauma is an essential yet often overlooked framework for understanding chronic distress ("ikizurasa") in everyday life.
 
 

Chapter 1  Where Does This “Ikizurasa” Come From?

・Explains how daily struggles such as difficulty connecting with others, oversensitivity, and chronic anxiety are rooted in hidden trauma.
・Provides relatable case vignettes (e.g., a sales manager who freezes under stress, a woman unable to open up to others).
・Introduces self-assessment checklists to help readers identify their own patterns of distress.
 
 

Chapter 2  The Vertical and Horizontal Threads of Trauma: Developmental Trauma as the “Fourth Developmental Disorder”

・Frames developmental trauma as interacting “vertical threads” (family, attachment) and “horizontal threads” (society, relationships).
・Explains how chronic, repeated relational trauma accumulates and manifests as pervasive difficulties.
・Positions developmental trauma alongside developmental disorders, proposing it as a potential “fourth developmental disorder.”
 
 

Chapter 3  The Loss of Self and the Many Symptoms of Trauma

・Details how trauma leads to the fragmentation or loss of one’s sense of self.
・Lists and describes 23 different symptoms linked to trauma, including dissociation, perfectionism, self-harm, chronic shame, panic, and addictions.
・Demonstrates the wide-ranging impact of developmental trauma on mental health, relationships, and daily functioning.
 

Chapter 4  Making Trauma Understandable: Stress Disorders and Harassment as Trauma

・Clarifies the mechanisms of stress disorders (PTSD, complex PTSD) and their overlap with developmental trauma.
・Frames harassment (power harassment, bullying, emotional abuse) as forms of trauma with lasting psychological consequences.
・Uses accessible models and diagrams to help readers understand how trauma operates in both individuals and systems.
 
 

Chapter 5  Overcoming Trauma

・Outlines practical pathways toward healing:
 1.Adjusting one’s environment to ensure safety
 2.Restoring the body through regulation and grounding
   3.Rebuilding the self through self-compassion and identity formation
   4.Processing traumatic memories
   5.Recovering connections with others
 
・Emphasizes that recovery is possible through both clinical approaches and daily self-care practices.

[Amazon Japan] [Publisher page]

Chapter 1 – People Who Are Hurt and Shaken by Others’ Words

This chapter portrays how easily people can be wounded by casual remarks, criticism, or the expectations of others. Through vivid real-life examples, it reveals how dependence on others’ evaluations creates anxiety, stress, and self-doubt. The reader begins to see that being “swayed by words” is not a personal weakness but a structural issue in communication.

 

Chapter 2 – Why Words Carry Such Heavy Weight

Here, the book explores the cultural, psychological, and social reasons why words in Japanese society are overvalued—sometimes to the point of suffocation. Drawing on insights from the social sciences, it analyzes why “listening well” and “valuing every word” became unexamined norms. This chapter sets the stage for challenging the conventional wisdom that language is always constructive.

 

Chapter 3 – Words Do Not Actually Carry Absolute Meaning

This chapter challenges the widespread belief that words inherently hold truth or value. It argues instead that words gain meaning only in context, and that over-reliance on language distorts self-perception. By reframing words as limited tools, readers are encouraged to free themselves from unnecessary suffering.

 

Chapter 4 – The Mechanisms That Make Us Swayed by Others’ Words

Here the book explains the psychological and social mechanisms that cause people to be overly influenced by what others say. It introduces the author’s original Public–Private Environment Hypothesis, showing how environments amplify or weaken the impact of words. This framework empowers readers to see how structural dynamics, not individual weakness, lie behind their distress.

 

Chapter 5 – Words Gain Life Only When They Are Let Go

This chapter reframes the act of “letting words pass through” as not avoidance, but as the very process by which language becomes truly alive. Drawing from philosophy, counseling, and clinical examples, it shows how releasing words from their heavy burden opens the door to authentic communication.

 

Chapter 6 – Never Be Swayed by Others Again!

The final chapter presents concrete strategies for reclaiming autonomy from harmful words. Readers learn to cultivate their own context, maintain resilience, and engage with others without being destabilized by careless remarks. It closes with a hopeful message: that freedom from the tyranny of words is possible, practical, and life-changing.

Why These Works Matter

 

Overview

 

Proven Market Traction in Japan

Over 40,000 copies sold across Ichitaro Miki’s titles, with two complementary bestsellers from leading Japanese publishers:

  • Developmental Trauma: The Real Cause of “Ikizurasa” (Chronic Distress or Difficulty in Living) (Discover Twenty One, 2023)

  • How to Let Other People’s Words Pass Through (Working English title; also translatable as The Skill of Not Taking Words Personally) (Forest Publishing, 2022)

 

Distinct Yet Complementary Contributions

Together, these works address two of today’s most pressing mental health concerns:

  • Hidden trauma and chronic distress (“ikizurasa”)—providing a clinical yet accessible framework for understanding developmental trauma and complex PTSD as a stress disorder.

  • Language-driven stress in relationships and workplaces—offering readers practical strategies to disengage from the excessive weight of others’ words.

 

Demonstrated Global Reach

Both titles have already been translated into Korean and Traditional Chinese, showing strong cross-cultural resonance and clear potential for further international editions.

 

 

"Developmental Trauma: The Real Cause of "Ikizurasa"(Japanese term meaning "chronic distress" or "difficulty in living") (Discover Twenty One, 2023)

 

A Groundbreaking Perspective on Understanding Trauma

This work is the first to clearly reposition trauma—not merely as a “psychic wound” but as a stress disorder—and to substantiate that claim with clinical evidence. By highlighting not only high-risk stressors such as abuse or disasters, but also the damaging effects of small, chronic stressors in everyday life, it reframes trauma as a universal human issue rather than a rare, exceptional condition. For this reason, it has been embraced not only by professionals but also by those directly affected.

 

From ‘Ikizurasa’ to Developmental Trauma

The book provides language for the vague but deeply felt “ikizurasa” (chronic distress, difficulty in living) that so many people experience. What was once dismissed as “personality problems” or “weakness” is shown to be rooted in developmental trauma—repeated stress in childhood within families, schools, or communities. This reframing allows readers to understand their struggles not as personal failings but as the result of identifiable mechanisms, opening a clear path toward healing.

 

Clinical and Scientific Relevance

The book aligns with the latest findings in neuroscience, psychiatry, and stress research. By explaining how chronic stress shapes brain function (amygdala overactivity, hippocampal shrinkage, prefrontal regulation failure, HPA axis dysregulation), it grounds psychological suffering in biological processes. This provides a bridge between scientific validity and clinical practice, making trauma understandable and actionable.

 

The “Fourth Developmental Disorder”

Drawing on Dr. Toshio Sugiyama’s concept of the “fourth developmental disorder,” the book illuminates how trauma-related symptoms (inattention, impulsivity, social fear) can closely mimic autism spectrum disorder or ADHD. By clarifying these distinctions, it prevents misdiagnosis and mistreatment, urging clinicians to assess both developmental history and current symptoms together. This approach has significant implications for accurate diagnosis and effective care.

 

Practical and Accessible

Through vivid case examples, readers can recognize themselves and their lived experiences. The book empowers individuals to see their symptoms as understandable responses to chronic stress rather than as personal flaws. It also introduces concrete paths for trauma care, including body-based approaches and attention to social safety, resonating with both professionals and general readers.

 

A Hopeful Message

Above all, the book delivers a powerful message: “Your suffering has a reason—and it is not your fault.” By redefining trauma as a stress disorder rooted in everyday life, it lifts the burden of self-blame and offers a realistic, compassionate framework for recovery. This makes it not only a pioneering contribution to trauma studies but also a guidebook of hope for countless individuals and families worldwide.

 

 

How to Let Other People’s Words Pass Through

 

Redefining the Power of Words

In an era where counseling and coaching often emphasize the importance of listening and empathy, this book offers a fresh counterpoint: words should not be overvalued as absolute truths. By reframing how we interpret language, it empowers readers to protect themselves from unnecessary psychological harm in everyday life.

 

Beyond Simple Techniques

Unlike many self-help titles that offer quick fixes, this book addresses the underlying structures that make words so impactful. Drawing not only from counseling practice but also from social science and the humanities, it situates everyday struggles within broader cultural and interpersonal contexts.

 

A Unique Theoretical Contribution

Central to the book is the author’s original Public–Private Environment Hypothesis, a new framework that explains how family, workplace, and social environments amplify or mitigate the impact of language. This contribution has drawn strong interest from both practitioners and general readers.

 

Philosophical and Practical Depth

The work bridges the gap between lived experience and theory, echoing intellectual traditions that emphasize context and meaning-making. At the same time, it remains accessible, using vivid case examples to help readers recognize their own struggles and discover practical ways to regain balance.

 

Proven Reader Resonance

Praised on platforms like Amazon Japan, the book has resonated strongly with readers who struggle with excessive sensitivity to others’ words. They report that the book offers not only reassurance but also a concrete shift in perspective—transforming what once felt like a personal weakness into something understandable and manageable.
