The Kokusai Jujutsu Kenkyukai

The International Jujutsu Research Society

Hyou-ha Bankoku Jujutsu was introduced to Australia in the late 1960s by Master Raymond LEA Saiko Shihan. At that time Master Lea was a newly graded black belt student of Professor Kam Hock HOE.

As a serving member of the RAAF Master Lea learnt his jujutsu direct from Master Hoe at his two McCallister Road, George Town, Penang dojos, in the garden of Master Hoe's home at Chee Seng Gardens and at the RAAF Base Butterworth dojo.

In the above photograph taken by Master Hoe in 1969 you will notice a very young Graham Rennie next to Master Lea and an even younger Errol Perera the second head master of Hyou-ha Bankoku Jujutsu standing three from the left in the back row

In the early 1970s Master Lea returned to Darwin in the Northern Territory where he became a member of the Northern Territory Police Force. With his martial arts background he was soon moved into a role as self defence instructor to the police and eventually into a role at the Darwin Police and Citizens Youth Club.

The IJIA Founded: In 1972 Master Lea established a dojo at the PCYC as one of the PCYC’s public recreational offerings. This group became the first Kokusai Jujutsu Gakuin of Australasia or International Jujutsu Institute of Australasia (IJIA) dojo. This dojo flourished until Christmas of 1974 when Darwin suffered the ravages of Cyclone Tracey.

Sadly, one of our students, Charles, “Chas” Dibua died as a result of injuries received during the cyclone. With Darwin largely uninhabitable most of Master Lea’s students were forced to move away. Master Lea remained in Darwin for a time before eventually transferring to the Australian Federal Police in Brisbane so that he could join his wife and his parents who had been evacuated to Brisbane after the cyclone. While in Brisbane Master Lea assisted Michael Ferguson in his Brisbane dojo before establishing a series of dojo in and around Brisbane.

One of Master Lea’s senior students, John Collett Shihan, temporarily relocated to Canberra after Cyclone Tracey. Collett Shihan established a Hyou-ha Bankoku Jujutsu dojo at the Corroboree Park YMCA and at the St Edmund’s College. These dojo were operational for a year or so before Collett Sensei returned to Darwin.

Before returning to Darwin Collett Shihan assisted Graham Duck Shihan, another of Lea Danna’s seniors establish a dojo at the Australian National University (ANU) Drill Hall. The drill hall dojo was in place for many years until it relocated to the ANU Sports Union building before passing into the control of students of Duck and Collett Shihan. Duck Shihan is no longer active in training, however, now living in Brisbane, he keeps in touch with Master Lea and occasionally joins him and Collett Shihan on grading panels.

On his return to Darwin Collett Sensei re-established the old Darwin PCYC dojo along with the “Gardens Road” dojo not far down the Gardens Road from the Darwin Botanic Gardens. The Gardens Road dojo was used by Collett Shihan and the late Kim Hanley Sensei to get in some “private” senior practice while dodging the occasional mishit golf ball.

Collett Shihan continues to teach small numbers of students, mostly senior martial arts practitioners from other arts such as karate and hapkido at his Minaputa dojo.

In 1977 Kim Hanley Sensei returned to Townsville to complete his tertiary studies. On returning to Darwin Kim began training with Graham Waite Sensei, a student of Master Rajathurai (Raj) Gurasami. Sadly Kim passed away on 15th July 1994, at that time Kim was ranked Godan, Kuatsu Senmonka in Hyou-ha Bankoku Jujutsu.

Master Lea re-enlisted in the RAAF initially as a PTI (Physical Training Instructor,) eventually being made responsible for developing PTI train the trainer courses for fitness, battle field self defence and other related courses. Master Lea established dojo at each of his postings within the RAAF until his retiremen from military service.

To this day Master Lea teaches a small number of students at his home in Brisbane and is in great demand to share his knowledge with other martial arts organisations

Master Hoe’s senior direct students, who are known as “second generation masters” all maintained a close personal connection with Master Hoe. Each had their own personal organisation through which they propagated the jujutsu that Master Hoe taught them. Relationships between his senior students varied, some close, some less so. As a result, unfortunately, there was never a strong organisational structure outside of Master Hoe’s hombu dojo.

It became clear over the years that Master Hoe taught different things to different people. To some he taught more; to others he changed what he taught a little. This occasionally resulted in conflict when practitioners from different groups got together but it was never a serious issue.

After Master Hoe’s passing in late 1990 we entered a period of stagnation and disunity. This resulted in an even greater fragmentation of his legacy, but as is often the way with these things it wasn’t really a problem, those seniors with a commitment to his legacy simply continued doing what they had always done; practice his Hyou-ha Bankoku Jujutsu.

The Kokusai Jujutsu Kenkyukai Founded

By the end of the 1990s Master Lea and a few of his seniors were talking about the need to re-establish a public presence for the way that they had always practiced Hyou-ha Bankoku Jujutsu. In 2000 they established the Kokusai Jujutsu Kenkyukai, the International Jujutsu Research Society (IJRS) with it's aims of researching, teaching and promoting Master Hoe's jujutsu without fear or favour to anyone with a genuine interest in learning.

The Kokusai Jujutsu Kenkyukai continues today quietly researching and teaching the art in a relaxed, friendly non-political environment. Membership of the society is open to any one wishing to learn Hyou-ha Bankoku Jujutsu. We are an idependant organisation. We will recognise any genuine grades or qualifications held in any bone fide martial disciple. We will issue a provisional rank equivalent to the external rank and afford all courtesies due a jujutsuan of that rank with the expectation that they will eventually catch up to that rank in our jujutsu.
