It is with great sadness that I must announce the closing of Danzan Ryu Boston. We have had 4 exciting and fun years exploring the jujitsu and restoration techniques handed down from master Okazaki. I’d like to say thank you to all of the people who have come in for deep tissue body work over the last several years. Also a big thank you to all of the students who have come in to let me influence their martial arts training, it has been an honor. Our last day will be August 31, 2016.

Danzan Ryu Boston Martial Arts

Danzan Ryu Jujitsu is a complete and complex martial art system of Japanese origins and Hawaiian influence founded in the early 20th century by Master Henry Seishiro Okazaki. It incorporates a wide range of techniques from throwing and grappling to striking, joint locking and choking.

Jujitsu, or "Gentle Art", takes its meaning from the practitioner defending themselves from any number of attacks not by brute strength, but in yielding circular movements. While very physical martial art system is taught, the practitioner is also developing a mental calmness and clarity so that situations can be diffused without the need for violence.

Sensei Ryan Shawgo began studying Danzan Ryu jujitsu in 2002 with Sensei Joshua Grant in Joshua's apartment in South Boston. They eventually moved to the MIT Kodenkan club to train as throwing and falling in the apartment was not possible. Ryan trained at MIT under the Club's co instrctors Stephen Balzac and Joshua Grant. In the spring of 2009, Joshua and Ryan moved to Brandeis University in Waltham, MA to begin a club there, Danzan Ryu Boston. DZR Boston moved to its current location, outside of a university environment, at 51 New St. Cambridge, in 2011.

In 1990, he began his jujitsu training with the Boston Guardian Angels, later being promoted to Chapter Leader and Martial Arts trainer for the group. He also helped train the Tokyo Guardian Angels while living in Japan in 2003. His study of DanZan Ryu jujitsu started in 1995 with Professor Tom Ryan at Palmetto Jujitsu and Healing Arts in Lexington, SC. Joshua received his shodan (1st degree black belt) from Sensei Ryan in 2003 and his yandan (4th degree) in 2012. Joshua currently studies Daito Ryu Aiki Jujitsu with Roy Goldberg Sensei.
