About us

Who are we?

We are a small and dedicated dojo, committed to the study of Hakko Denshin Ryu Jujitsu located in Denver Colorado. (八光伝心流ー柔術。)


What do we practice?

Hakko jujitsu(八光柔術) is a traditional Japanese style of jujitsu that emphasizes and teaches a non-violent and energy based form of self-defense that, in addition to joint locks, throws and other common practices, teaches the art of targeting pressure points that lie along the meridians where energy flows. 

Incorporating Healing with Jiujitsu

In order to attain a higher level of understanding of the meridians and energy flow, we also practice shiatsu(指圧), or Japanese pressure therapy which has healing benefits.

Techniques you will learn

Learning both the jujitsu and the shiatsu wazas(技), or techniques ,along the same meridians gives Hakko Denshin Ryu(八光伝心流) practitioners a unique insight and advantage in dealing with opponents and healing.

Our Teaching Philosophy

Central to our practice is learning how to abandon strength and force and apply techniques with minimal effort. A hallmark of the style is that techniques look weak to the uninitiated but are in fact very powerful. In fact, finding how to deepen one’s relaxation while continuing to perfect one’s techniques, is for all Hakko practitioners a lifelong pursuit.  Remaining soft and pliable is required in order to increase one’s power and effectiveness in the application of all Hakko techniques, a paradox difficult for many and must be felt to be truly understood. Classes are intentionally small as techniques must be felt from teacher to student to be understood.

History of Hakko Ryu

Hakko Ryu jujitsu(八光流柔術。) was founded by Soke Ryuho Okuyama(奥山龍峰) in 1941, at the beginning of the second world war, and directed by Soke Shodai (初代。first) Okuyama until his passed away in 1987, and since that time to the present has continued under the direction of his son Soke Nidai Okuyama. In the 1980’s, Shodai Okuyama awarded the rank of Menkyo Kaiden San Dai Kichu(免許 皆伝 三大気中)to Soke Michael La Monica, making Soke Lamonica the highest ranked Hakko practitioner outside of Japan, and first non-Japanese to be given that rank. 



Legacy in the modern generation:

After Soke Shodai Okuyama passed away in 1987, Soke Lamonica started a new organization, Hakko Denshin Ryu of North America, of which The Colorado Hakko Dojo is a branch member.  Mr. Lamonica has a long history in law enforcement and has trained many in law enforcement, FBI and corrections in the practical techniques of jujitsu in order to safely subdue subjects.
