“The techniques of Hakkoryu are nothing but the pure self-protection instinct that prepares your spirit to face urgent matters of life and death. That is, when one encounters violence, it can be said that Hakkoryu provides natural, simple, and practical methods that enable one to calmly face imminent peril and move on without hesitation to capture and punish assailants reasonably and easily in an instant.”

Nestled along a back street in a town one hour northwest of Tokyo by train, is a dojo unique in modern Japan. It is called the Hakkoryu So Hombu Dojo, and was founded by Shodai Soke Okuyama Ryuho. This dojo provides for training in the arts of Hakkoryu Jujutsu.

One must experience and feel the teachings of Hakkoryu in order understand and make progress. Hakkoryu Jujutsu practitioners endeavor to prevent acts of violence before they occur. This is a primary belief in Hakkoryu. We say, “Idomazu” or “no challenge” which includes this idea.

While Hakkoryu applies pressure techniques on Keiraku to defend oneself or pin down an opponent when one is being attacked, applying pressure techniques on Keiraku is also the essential theory of Koho Shiatsu.
