Reading The Phantom Kumite of the Oyama Dojo: An Introduction for Karate History Researchers

Before Mas Oyama’s group was formally organized in 1964 as the International Karate Organization Kyokushinkaikan, it existed as a small, informal dojo known simply as the Oyama Dojo (大山道場, Ōyama Dōjō), a place later immortalized in Kajiwara Ikki’s manga Karate Baka Ichidai (空手バカ一代, roughly “Karate Idiot Generation”). Remarkably little first-hand technical testimony survives about what kumite (組手, sparring) actually looked like inside that early dojo. Maboroshi no Ōyama Dōjō no Kumite [The Phantom Kumite of the Oyama Dojo] is a rare exception: its author, Watanabe Kazuhisa (渡邊一久), joined the Oyama Dojo himself and rose to become its first home-grown shihandai (師範代, senior instructor / assistant headmaster). Here he sets out, with technical explanations, the actual sparring methods of Mas Oyama himself and of senior disciples such as Ishibashi Masashi (石橋雅史), Minamimoto Ichirō (南本一郎), Yasuda Eiji (安田英治), and Kurosaki Kenji (黒崎健時) — the very men later fictionalized in the manga, now speaking in their own, first-person technical voice.

Overview

The book runs to seven chapters framed by a foreword and an afterword. Chapter 1, “Youth at the Oyama Dojo” (大山道場の青春, Ōyama Dōjō no Seishun), is Watanabe’s own memoir of joining the dojo and rising to become its first shihandai. It portrays the individual kumite styles of senior figures such as Minamimoto Ichirō (南本一郎; note that the reading of the surname 南本 is not entirely certain and could also plausibly be read “Nanmoto”), Ishibashi Masashi (石橋雅史), Yasuda Eiji (安田英治), and Kurosaki Kenji (黒崎健時). It also recounts episodes that appear to be the real-life basis for scenes in Kajiwara Ikki’s manga Karate Baka Ichidai, such as Watanabe recounting his own fighting experience directly to Kajiwara, and the well-known story of Watanabe fighting twenty-eight opponents in succession. Chapter 2, “Mas Oyama’s Own Kumite,” describes Oyama’s stance, blocking, and simultaneous strike-and-block technique as Watanabe observed them firsthand. Chapters 3 and 4 move from basic to advanced kumite as it was actually taught in the dojo, in the style of a technical manual. Chapter 5 is a dialogue between Watanabe and Yasuda Eiji, touching on the technical background of Yasuda’s signature “predictive front kick” (予告前蹴り, yokoku mae-geri) and anecdotes about Oyama, such as his bending a 10-yen coin between his thumb and forefinger. Chapter 6 revisits the kumite of Kurosaki Kenji, Ishibashi Masashi, Minamimoto Ichirō, Yasuda Eiji, and Fujihira Akio (藤平昭雄; some tables of contents render the given name as 照雄, “Teruo,” rather than 昭雄, “Akio” — this is most likely a typographical inconsistency in bookseller catalogue data rather than two different people, though we have not verified this against the physical book). Chapter 7 covers practical self-defense applications, including defense against a knife.

At the time of publication, the book’s editor, Yamada Eiji (山田英司) of Full-Com, wrote on his own blog that the book’s chief significance was that “Mas Oyama’s own kumite technique is introduced for the first time.” Independent, first-person technical testimony about kumite in the Oyama Dojo era is genuinely scarce; much of what is publicly known has instead come down through later organizational histories, biographies, or the Karate Baka Ichidai manga. This book’s value lies in hearing that history in the words of people who were actually there. Notably, Yasuda Eiji, Watanabe’s dialogue partner in Chapter 5, passed away in 2013, the same year this book was published, which makes this dialogue one of relatively few surviving late testimonies from him.

About the Author

Watanabe Kazuhisa (渡邊一久) was born in 1937. According to the publisher’s own author biography, he joined the Oyama Dojo at the age of twenty and reportedly earned his black belt within about a year. He trained under Mas Oyama himself and senior figures including Ishibashi Masashi, Minamimoto Ichirō, Kurosaki Kenji, and Yasuda Eiji, and was appointed the dojo’s first home-grown shihandai. He is said to have gone on to instruct many students who would later lead their own branches of Kyokushin karate, including Oyama Shigeru (大山茂, Mas Oyama’s younger brother), Nakamura Tadashi (中村忠), Ashihara Hideyuki (芦原英幸, founder of Ashihara Karate), Ōsawa Noboru (大沢昇), and Katō Shigeo (加藤重夫) — all according to the publisher’s own account. After Mas Oyama’s death and the subsequent split of Kyokushinkaikan into rival organizations, Watanabe reportedly served as an advisor to several of them, but at the time of this book’s publication he held no official post in any Kyokushin organization and was said to be devoting himself to passing on the techniques of the Oyama Dojo era, under the title “International Denshō Karate-dō Sōshihan” (国際伝承空手道総師範, roughly “Grand Master of Internationally Transmitted Traditional Karate-dō”).

The book does not explicitly identify a ghostwriter or state that it was reconstructed from interviews. However, since it was edited by Full-Com before being published by Tōhō Shuppan, some degree of editorial shaping is likely, even though the voice throughout is presented as Watanabe’s own. Readers should keep the note below in mind.

A Note on Reading This Book as a Historical Source

Before Reading This Book as a Historical Source

Karate books are written not by academic historians, but by practitioners, commercial writers, editors, and publishers. For that reason, please do not take everything written here, or in the book this article discusses, as settled fact. In most cases the author has no intent to deceive, but a careful, critical reading is always warranted.

Here is why:

• Many such books were ghostwritten, or reconstructed by a writer from interviews, so the final text may owe as much to an editor’s or ghostwriter’s judgment as to the named author’s own words.
• Personal opinion is sometimes presented as though it were established fact. Some passages exaggerate what actually happened, or describe the world as the author or publisher wished it to be seen, rather than as it truly was.
• Some books state as fact things the author only knew secondhand, and some simply get facts wrong.
• Older books deserve particular care about who they were written for. Beyond ordinary exaggeration, some contain deliberate distortions, and it is not unusual for the same author to say contradictory things in two different books.
• Older works may also contain language that reads today as discriminatory, exclusionary, or otherwise inappropriate, along with claims that unfairly, and sometimes falsely, criticize other people. Such passages can feel jarring to a reader today, but it is worth remembering that this kind of language was, at the time, often expected by someone, whether the author, the publisher, a bookseller, or the readers themselves, and it sometimes served as a way for an author to set himself apart from rivals.

Even so, we believe that uncovering fact from within exaggeration, bias, and occasional falsehood is exactly what karate history research requires.
