The techniques of Dentokan Aiki Jujutsu, while extremely efficient, and frequently painful, are designed to quickly neutralize an attack, while causing as little lasting damage as possible. However, these skills, amplified by the understanding of the previously mentioned henka, gensoku, and oyo, make possible a graduated response to any attack. One's response may be one of neutralization followed by a non-destructive restraint or pin of an opponent to an all out counter attack, if circumstances require such measures. These characteristics make Dentokan Aiki Jujutsu well suited for defensive tactics training for law enforcement personnel.
Dentokan Aiki Jujutsu was established in Japan by Colonel Roy J. Hobbs, Kancho in 1997, with the encouragement and blessings of his teacher, Irie, Yasuhiro, Shihan. Hobbs Sensei began training in Hakko-ryu Jujutsu in 1965, receiving the title of Shihan in the art in 1984 directly from Okuyama, Ryuho (Yoshiji), Shodai Soke and Founder of Hakko-ryu. Hobbs Sensei later received Menkyo Kaiden, complete transmission, in Kokodo-ryu, a branch of Hakko-ryu, in 1997 from Irie Sensei, one of the senior-most students of Okuyama, Shodai Soke. The Chief Instructor for Dentokan Aiki Jujutsu at Shindokan Dojo is Mr. Erik Johnstone, a student of Hobbs Sensei, Menyko Kaiden and Kancho, Sekai Dentokan Bugei Renmei.
Shindokan Budo Dojo offers regular classes in traditional Japanese Aiki Jujutsu (Jujutsu employing "aiki" principles), and Goshinjutsu. Derived directly from the close quarter combat methods of the samurai, Jujutsu offers practical, modern self-defense.
Shindokan Dojo offers training in Dentokan Aiki Jujutsu, a Japan-recognized branch of Hakko-ryu Jujutsu. The term jujutsu can mean soft or pliable art. This can be interpreted to refer to methods of combat that employ the principle of ju, flexibility or softness, in the execution of techniques. Classical and traditional Japanese jujutsu and Aiki jujutsu arts utilize combative methods that were originally developed and employed by the samurai on the battlefields of Feudal Japan. During the relative peace of the Edo Period, these methods were modified and expanded upon, transforming them from "battlefield" methods into arts more suitable for use as unarmed or lightly armed life-protection systems. While the term jujutsu is now quite familiar in our society, legitimate jujutsu and Aiki jujutsu traditions, which by definition will have a verifiable and recognized lineage rooted in Japan, are comparatively uncommon outside of Japan, especially when compared to arts such as Aikido or Karatedo.
In fact, instruction in an authentic jujutsu or Aiki jujutsu offered at our level of experience, accreditation and class frequency can be found at no other dojo in our area, and is one of the elements that make Shindokan Dojo unique among all schools in our region. The technical spectrum of Dentokan Aiki Jujutsu typically include sophisticated joint locks; immobilizations; chokes and strangulations; strikes; throws; manipulations of vital points; and aiki, or subtle physical manipulation and mental disruption. Descended from the Daito-ryu Aikijujutsu of Takeda, Sokaku, Dentokan Aiki Jujutsu includes all of these combative methods, and is a system of Aiki Jujutsu that, like its predecessor arts, is noted for very relaxed and soft, yet extremely effective execution of technique to neutralize an attack. Dentokan Aiki Jujutsu employs a very structured, yet progressive, principle-based training methodology that shares many similarities to the transmission of the older koryu jujutsu from which it is descended. The syllabus closely follows that of the original Hakko-ryu and Kokodo-ryu, retaining the waza catalogues of Shodan-gi, Nidan-gi, Sandan-gi, Yondan-gi, Shihan-gi, Kaiden-gi and Sandaikichu-gi. Training typically focuses on the waza within each specific set, followed after a time by henka waza, or variations of the formal waza. Henka may be a variation deals with attacks such as various strikes, kicks or grabs that one may encounter in a self-protection situation but may not be included in the formal waza of a given set. Henka waza are studied in order to increase one's knowledge and skill and to explore the gensoku, or underlying principles contained within each waza. Through the internalization of the gensoku, one may explore the depths of the art more fully through the creation of goshin oyo, the practical applications of the waza and principles woven throughout the art. Dentokan Aiki Jujutsu, while an effective life-protection art, is also based on a humanitarian approach to self-defense, following Okuyama Sensei's teachings of no challenge, no resistance, no injury, giving it a moral and philosophical basis that is very similar to the related art of Aikido.
