To approach the very core of Kyudo by means of fact is the chief ambition of this work. What it treats is the "physical data" that precede technique and form—an area seldom addressed in the literature of Kyudo. Measured values of bow strength, images that render the arrow's motion visible through high‑speed filming, and records of inquiries born from long‑standing doubts—these constitute the material at hand. What lies here is neither speculation nor doctrine, but merely the quiet presence of fact. Kyudo, being a discipline of profound spirituality, has often shunned physical analysis. Yet precisely because its inner world is deep, one may reasonably ask whether an objective foundation is not required. This book begins from that question. The author does not intend to "scientifically explain" Kyudo, nor to redefine correct shooting. Rather, when he noticed certain physical errors embedded in the knowledge and papers circulating within the Kyudo community, there arose a simple desire to "verify more" and "see more." That desire is the origin of this volume. Still, the facts made visible are but fragments of truth. What the high‑speed camera captures is not truth itself, but a sliver of light that guides us toward it. Where, then, is Kyudo to go from here? Shall its spiritual dimension be emphasized, or shall its scientific understanding be deepened? The answer is left to the reader. Yet if one is to consider Kyudo as martial art, performing art, or sport, knowledge of its minimal physical facts can scarcely be deemed useless. This is not a book that seeks to shake Kyudo. But those who love Kyudo deeply will find that something within them inevitably trembles, and that something new becomes visible—such is the nature of this work. |
