What if the person who diagnosed your cancer… wasn’t even a doctor?

This is not an exposé.

This is a confession.

It’s a true story of systemic failure—
told by a Japanese physician (pathologist) who remained silent for too long.

In Japan’s medical world, a licensed dentist falsely claimed to be a medical doctor (MD) and, in every practical sense, operated as one—functioning as a “shadow MD” who gaining international prestige and even contributing to official disease classifications.

Why?

Because the system enabled him.

In Japan, a legal and cultural gray zone allows non-physicians to issue medical pathology-based diagnoses—judgments that carry the weight of a physician’s diagnosis and shape clinical decisions.
Within this ambiguity, the dentist effectively operated as a true medical doctor—in both clinical and academic settings.
By falsely using the MD title in scholarly publications, he further blurred the line between appearance and reality—becoming, in both form and function, indistinguishable from a true physician.

This book is not only a personal testimony rooted in the author's experience within Japan’s ambiguous medical system.
It also examines how Japan’s thousand-year tradition of avoiding clear responsibility—through silence, social harmony, and atmospheric reading—has shaped this unique situation.

This silence—cultural, institutional, and professional—forms the quiet foundation of what we now call exported risk.

📌 This structured journey forms a bridge

—from one false credential,

through Japan’s cultural DNA, to the future of global diagnostic integrity

—culminating in the question:

Who diagnosed you?

For those who believe that medicine must answer not only to scientific truth,

but also to ethical responsibility—

this book asks a question long ignored and offers a perspective long missing.

(Note: “medical pathology” here refers to pathology in internal medicine and oncology, beyond oral pathology or dental fields.)
