🥋 Can a single punch truly end a fight? We're diving deep into the powerful and pervasive concept of One Hit, One Kill, or Ikken Hissatsu. This doctrine had a huge influence on modern karate's development, but where did it come from?

Most likely source: the fierce Japanese swordsmanship school, Jigen-ryu, whose philosophy is to kill with a single, decisive stroke. We trace how this singular focus shaped modern kihon , competition scoring , and the methods of pioneers like Gichin Funakoshi.

We debate the value of Ikken Hissatsu as a principle of total commitment versus its misapplication to the continuous, positioning-focused methods of the antique kata.

Tune in to learn where Ikken Hissatsu belongs in your training - and where it doesn't.
