Unlike the common misconceptions shaped by popular culture, using concealed weapons such as shuriken is, in fact, a highly tactical support technique. Through surprise attacks and simple methods that make them difficult to defend against, they are used to create advantages and secure victory in combat.
This workshop will cover a brief history of shuriken-jutsu, the design logic behind the tools, and basic application demonstrations. Participants will then use safe practice tools to experience hands-on operation and tactical thinking, gaining a direct sense of how such weapons can function in real combat scenarios.
