.. 剛柔流の型を考察すれ明らかなことですが剛柔流は剛(打撃技)と柔(関節技・投げ技、締め技)のそれぞれが有機的に連携した空手を体現する武道です。この原則は身体的のみならず精神的な面にも当てはまります。このウェブサイトは伝統的な剛柔流の技術と哲学を世界と共有することにあります。その際、1970年代以降に世界的に流行したブルース・リー、総合格闘技、柔術、合気、WKF、極真などの理論や技術を借用して説明しないように注意しました。昨今そのような傾向が見られます。すべての写真とビデオは私のアマチュア作品です。ご理解をお願いいたします

It is clear if you consider the Kata of Goju-ryu, which has a lot of circular motion,Goju-ryu embodies a karate style the each Go (striking techniques) and Ju (joint manipulation, throws, and tightening techniques) worked together organically.These principles apply not only to physical technique but also to the spirit, where each is essential to the other.
The purpose of this website is to share the techniques and philosophy of traditional Goju-ryu with like-minded practitioners. However here history and techniques are presented independently, avoiding knowledge popularized by media trends after 1970, such as Bruce Lee, MMA, Jujutsu, Aiki, WKF, and Kyokushin.
Please note that all photos and videos are my amateur work; I appreciate your understanding

フィリップ・コンジョクラッド著「泉川寛喜 剛柔流先駆者の遺産と教え」
Filip Konjokrad
"Kanki Izumikawa-Legacy and Teachings of a Goju Ryu Pioneer" →Amazon
..剛柔流空手史研究者として国際的に有名なカナダの研究者による3冊目の著書。広報では「この本により剛柔流の重要な先駆者である泉川寛喜の生涯と教えが初めて深く探求された。日本語からの新訳、インタビュー、未公開の情報と写真を豊富に含む 」とある。
 比嘉世幸の一番弟子であった沖縄出身の泉川氏は1939年に本土で沖縄剛柔流道場の組織的活動を開始して以降、多くの門下生と団体を輩出し1967年に惜しくも59歳で亡くなった。その軌跡を膨大な文献と現地調査に基づいてたどった本書は剛柔流の本質と本土での展開を理解するための貴重な文献である。日本に類書は存在しない。
This is the third book by the author, a promising researcher in karate history.
According to the author, "For the first time, the life and teachings of an important Goju-Ryu pioneer, (Kanki Izumikawa) are explored in depth. The book includes new translations from Japanese, interviews, and a wealth of previously unpublished information and photos.”
Although Kanki Izumikawa from Okinawa,the top student of Seiko Higa,aproduced many students and founded several groups after 1939, he sadly passed away in 1967 at the age of 59. Had he lived longer, the landscape of Goju-Ryu karate might have been profoundly different.
This is a valuable resource for those seeking to understand the essence and evolution of Goju-Ryu karate. There is no similar book like it in Japan.→detail

Shihan Josep Claramonte, the top fighter of Yuzenkai Spain, renewed his European Championship title in CJJ (Combat JuJutsu; Full Contact, Close Contact, Ground Fight, Self-Defense) on May 17-19 in Spain.
 This year's tournament brought some surprises, as all competitors in his category had karate backgrounds, making for intense and thrilling matches. Despite the fierce competition, he achieved an impressive result.

The legend & the achievements of I. Kato, one of the founders of Yuzenkai
In 2023, Yuzenkai lost one of its founders. At the end of the year, I reflected on the achievements, legacy, and memories of Isamu Kato (1941–2023) with Shihan Naganuma.
Note: The name "Yuzenkai" comes from the founders' names, Isamu Kato (加藤勇) and Yoshiaki Naganuma (長沼善秋). "Yu" (勇) is from "Isamu" (勇), and "Zen" (善) is from "Yoshi"-aki (善秋).

ヨセプ師範は現代最強の剛柔流ファイターと言える。スペインをはじめ国際的な総合格闘技大会に参加し剛(打撃)でも柔(投げ・関節・固め・締め)でも戦ってその実力を金メダルで実証してきた数少ない空手家である。9年前に厚木で修業して以来剛柔流の実戦使用の体現をめざしてきた。2024年12月に厚木に凱旋里帰り。



The strongest modern Goju-ryu fighter
I received great news the other day. I share this as an honor to all Yuzenkai members.
“Dear Omoto Kancho, It is with great pleasure that I offer a World Championship to the glory of Yuzenkai.I became ICJJIF World Champion in Latvia.9 fights to get gold medal and world title.
I offer this title to you and all members of Yuzenkai.
Josep Claramonte,Yuzenkai Spain”

 He is a true Goju-ryu fighter who embodies the ideal unity of "Go" (thrust, kick, strike) and "Ju" (throws, joint techniques, tightening, hardening) in real combat. He is the strongest modern Goju-ryu fighter.
 Although there are many Goju-ryu practitioners around the world, he stands alone in proving this mastery with a world gold medal in mixed martial arts

.. 金城裕 (1919-2013)。沖縄生れの空手家。大正時代~他界(2013)まで空手の発展に流派を超えて誠実に寄り添ってきた彼の大著「唐手から空手へ」(日本武道館)の紹介。
「手(て)→唐手(とうで)→唐手(からて)→空手(からて)」の変遷を戦前の沖縄県学務課や大日本武徳会との関係から解明し、それによって武術空手から教育空手、スポーツ空手へと変化すると共に同時に空手観、型、分解の変容が生じたことを実証した。
 4大流派集団の功と罪、全空連の功と罪、世界空手連盟(WKF)の功と罪、これからあるべき空手の姿について本人の体験と驚異的な学識から語った後世の空手家への遺言の書といえる。
 Now, (1) Te (手), (2) Toude (唐手), (3) Karate (唐手; with the pronunciation changed), and (4) Karate (空手; with kanji changed by the Okinawa Education Bureau in 1939) are used interchangeably, which leads to confusion.” Kinjo explains these distinctions as follows:
(1) Te (手): An ancient indigenous Okinawan martial art.
(2) Toude (唐手): The 19th-century term for Te, emphasizing its Chinese origins.
(3) Karate (唐手): An educational form of karate developed in 1905 by Anko Itosu (糸洲安恒) for secondary school physical education in Okinawa.
(4) Karate (空手): A version with changed kanji, influenced by political intentions preceding the Sino-Japanese War.
 Kinjo observed that these four concepts have all come to be called "karate," leading to confusion among practitioners worldwide. "Which concept of karate have you heard about: (1), (2), (3), or (4)?” he asks readers, encouraging them to think critically about karate's origins.
 Kinjo's book also discusses the advantages and drawbacks of the four major post-WWII karate organizations, including the JKF and WKF. This work serves as his legacy to future generations, sharing insights from his extensive experience and profound knowledge, as well as his vision for the future of karate.→detail詳細

 
 金城師範が1956年から1957年にかけて発行した『月刊空手雑誌』に掲載された写真。 本土における剛柔流の組織的な道場活動は1938年に始まった。戦災により中断し戦後に復活。これらの写真は復興遂げ、生き生きとした当時の剛柔流の姿を見せてくれる。 
 The photos in "The monthly Karate magazine" published by Shihan Kinjo from 1956 to 1957. They are our masters and great seniors.
 Okinawa Goju-ryu karate was introduced from Okinawa to the mainland in 1938, was discontinued due to war damage, and was revived.  
 These pictures show what Goju-Ryu Karate originally was. They performed throwing techniques as the name Goju-ryu. It was also integrated with Kobudo from the beginning.
 I,Kancho of Yuzenkai, sometimes say to my stusents that you should understand Gojuryu not only as sports but also as traditional culture which has been going on since the 14th century. The basics and Kata we practice have 500-year history.

フィリップ・コンジョクラッド師範の錬士論文の受領について
..外国人がこの様なマニアックな剛柔流空手史の本を2冊も公刊するのは驚きである。著者は膨大な日本語文献を収集・解読し2018年に来日し関東と東北の各地で関係者に調査した。
著者の新機軸は1934年に沖縄から泉川寛喜が比嘉世幸および許田重発の系統の剛柔流を本土へもたらし組織的な道場活動を開始していたという歴史的事実を英文で世界へ発信したことである。以下、彼からの審査依頼文。

 「私は山口剛玄 (1909 ~ 1989 年) が宮城長順 (1888 ~ 1953 年) の最も重要な弟子であり日本の剛柔流を創設したと教えられました。2008 ~ 2010 年頃、私はさらに研究し始めました。そして比嘉世幸(1898~1966年)、八木明徳(1912~2003年)、宮里栄一(1922~1999年)など宮城の他の弟子たちについて学ぶべきことがたくさんあることを発見しました。そしていくつかのビデオで山口の剛柔流と沖縄の剛柔流の明確な違いに気づき、それが私の好奇心をそそりました。2008年から2016年にかけて私はカナダで沖縄からの講師の数多くのセミナーに参加しました。 2016年に私は勇善会館長尾本師範から指導を受ける許可を頂きました。勇善会の系譜は比嘉世幸やその一番弟子の泉川寛喜にたどりつきます。私は比嘉・泉川と他の剛柔流との違いを探求し、私は比嘉系の剛柔流が最も古いバージョンを表していると確信しました。」
Shihan Filip Konjokrad (Canada) submitted his two books, “Goju-Ryu Toudi Jutsu Nyumon” (247 pages, 2017, ISBN: 978-1-387-29395-7) and “History and Stories of Goju-Ryu” (256 pages, 2018, ISBN: 978-0-359-31781-3), as his dissertation for Renshi (錬士) 5th Dan to GIKKU Yuzenkai Japan. He was awarded the Renshi title on July 26, 2022.
...Both books are rich in historical detail and showcase Konjokrad’s deep affection for Goju-Ryu, based on extensive Japanese materials and field research in Japan. I am honored to have perhaps influenced his motivation for research, as he expressed in a letter to me.


 "We were taught that Gogen Yamaguchi (1909–1989, 山口剛玄) was Chojun Miyagi’s (1888–1953, 宮城長順) most important student and founded Japanese Goju-Ryu. Around 2008–2010, I began researching further into Goju-Ryu and realized there was much more to discover. I learned about Miyagi’s other students, like Seiko Higa (1898–1966, 比嘉世幸), Meitoku Yagi (1912–2003, 八木明徳), and Eiichi Miyazato (1922–1999, 宮里栄一). I also noticed distinct differences between Yamaguchi’s Goju-Ryu and Okinawan Goju-Ryu in some videos, which piqued my curiosity.
..Between 2008 and 2016, I attended numerous seminars in Canada with Okinawan instructors. In 2016, I learned about Shihan Omoto (尾本師範), who agreed to teach me. Shihan Omoto’s lineage stems from Seiko Higa (1898–1966), whose most senior student was Kanki Izumikawa (1908–1967).In my books, I explore Seiko Higa’s teachings and how they differ from other Goju-Ryu schools. I believe Higa’s Goju-Ryu represents the oldest version of the style. I was particularly impressed by Shihan Omoto’s kata bunkai and research.”

Biography .. 館長  尾本一則 1958年生
早大大学院卒(文学修士)。元神奈川県立高校教員(定年)。教職(公民科(倫理)・空手部顧問:大会入賞指導多数)のかたわら沖縄剛柔流・沖縄古武道を海外へ指導、普及。現在12か国に支部を有する世界勇善会館長。→系譜
..Kancho OMOTO Kazunori (1958~) has studied Okinawa Gojuryu Karate under Shihan Yoshiaki Naganuma and Isamu Kato, the last students of Kanki Izumikawa (Seiko Higa's top student) since 1974. He graduated from Waseda University in 1980 ,and completed his graduate studies in Humanities and Social Science in 1982, earning a Master of Arts degree.
..
When he earned his black belt, Karate in Japan was undergoing a significant transformation, with the standardization and unification of Kata and kumite being politically promoted by the JKF. As the result, he believe that modern Goju-ryu karate was losing its fundamental principles in the movement. After that he has dedicated himself to systematic and theoretical research on Goju-ryu Karatedo, grounded in historical facts and traditions.
..After completing his M.A. degree, he worked as a high school teacher, consistently coaching karate clubs. Under his leadership, his students have achieved numerous accolades in all-Japan, metropolitan, and Pacific Ocean district competitions.
..Simultaneously, he began teaching ancient-style Gojuryu at his private dojo. From 2006 to 2007, he contributed to developing a large-scale e-learning system for high schools under the Board of Education. He also participated in an educational program for NHK (Japan Broadcasting Corporation) as the chairman of the committee focused on high school correspondence course education. This experience that significantly influenced the Yuzenkai method.
..In 2013, he succeeded to the position of Kancho of Yuzenkai and established the "Gojuryu International Karatedo Kobudo Union" (GIKKU). At the same time, he began sharing the results of his studies with Karate-ka worldwide through the internet.
..Following his retirement, he has taken on three roles: lecturer at a high school, Kancho of Yuzenkai Japan, and Grandmaster of the Gojuryu International Karatedo Kobudo Union. He is currently writing an book in English as a culmination of his knowledge in Goju-ryu Karate..
