Waneroo, Perth, 2 Dec 2024. Kyoshi Peter Hunt hosted a session to explore concepts in the book Breaking Through: The Secrets of Bassai Dai Kata. In that seminar, we looked at the underlying thought process which led to the publication which we referred to as “The JDK Method.”
Guest Contributor Shihan Leonard Montagnana participated in the Wanneroo event, and we’re excited to share his report on AJJJCBFI’s Academy News Summer 2025 Edition #95 below.
What is Bunkai?
The JDK Method is a distillation of two decades of work to answer the question “What is Bunkai?” It firstly considers the vagaries of preemption. Under duress, practitioners are hard pressed to read the combative landscape and accurately predict what is happening.
The other questions that may be asked are “What attack is coming my way?” or “Is it a left or right handed strike?” For this, we advocate for techniques to be used as multitools. Ideally, your one technique should apply to a left side attack, as does to a right side attack. Secondly, we assume failure of technique. The opponent is there to oppose you. Thus, it is to your advantage to prepare for that opposition. If resistance could shut down your tactic at any point, train for workarounds, and draw freely from your library of skills.
If you bunkai to you is simply one solution to one problem, you may need to revisit your training pedagogy. What is the end goal your training is leading you towards? Is it choreography? Or is it to acquire fight IQ?
The Breaking Through book eventually leads to the work on my historical fiction manuscript. For those practitioners who think a novel is beneath them, that operative word ‘fiction’ is there only so I may pick apart the facts from the truths. Stick with me, it’s going to be a compelling ride!
