The Sword Hidden in the Hand
The word ‘shuriken’ literally translates to ‘sword hidden in the hand,’ a name that perfectly describes its tactical purpose. Contrary to the ‘one-hit-kill’ depictions in movies, shuriken were rarely used as primary lethal weapons. Their small size and limited weight meant they lacked the stopping power to kill an armored opponent instantly. Instead, they were used as ‘metsubushi’ (eye-closers)—tools designed to distract, annoy, or wound an enemy to create an opening for a decisive sword strike or a quick escape. A ninja would often coat the tips of the shuriken in poison or bacteria to ensure that even a minor scratch could eventually prove fatal.
Types of Shuriken
There are two main categories of shuriken: the ‘bo-shuriken’ (straight spikes) and the ‘hira-shuriken’ (flat, star-shaped blades). Bo-shuriken were often easier to conceal and could be thrown with great precision, resembling large nails or needles. Hira-shuriken, the iconic ‘throwing stars,’ were designed to spin rapidly in flight, which stabilized their trajectory and allowed them to catch the air. These stars could have anywhere from three to eight points, and their shape was often dictated by the specific school or ‘ryu’ of the ninja clan. The Iga and Koga clans each had their preferred designs, which served as a sort of calling card.
- Bo-shuriken: Straight, cylindrical or four-sided spikes.
- Hira-shuriken: The classic multi-pointed throwing star.
- Distraction: Used to draw an enemy’s gaze away from the ninja’s movement.
Training in ‘shurikenjutsu’ involved not just throwing accuracy, but also the art of drawing the blades quickly from hidden pockets or folds in clothing. A ninja might throw several shuriken in rapid succession to suppress an enemy’s movement. In many cases, the mere sight of a shuriken flying through the air was enough to cause a momentary hesitation in an attacker, providing the split second a shinobi needed to vanish into the darkness. The shuriken remains one of the most iconic symbols of the ninja’s ‘soft’ power—the ability to control a fight through misdirection and harassment.
