The Sasumata (刺股) is a forked spear used in feudal Japan, created to immobilize criminals without seriously injuring them. Used by samurai and police, it was part of a trio of non-lethal weapons alongside the Tsukubo and the Sodegarami. Its design consists of a long staff with two sharp points and lateral spikes, preventing the target from grabbing the weapon.
Although it originated to capture opponents in the feudal period, the Sasumata still has a presence in modern Japan, especially in schools and public places, where it is used to safely contain intruders.

The Use of Sasumata in Modern Japan
Nowadays, the Sasumata has undergone adaptations: made of aluminum, with no sharp blades and a lightweight structure. The Japanese police use it as a tool for defense and containment, especially in situations of disturbances. Furthermore, many Japanese schools keep a Sasumata as part of their security kit against intrusions.
Why Use Sasumata in Schools?
Japan has low rates of armed violence, so the Sasumata is effective against unarmed or bladed weapon intruders. Its shape allows immobilization without causing serious injuries, providing quick protection until the authorities arrive.
Often, in addition to the Sasumata, schools also have protective shields to defend themselves and create a safe barrier when confronting an intruder. After immobilization, the guidance is to tie up and contain the suspect until the police take control of the situation.
In addition to schools, the Sasumata can also be found in hospitals, community centers, and even train stations. In places where firearms are rare, its presence provides an effective means of control without the need for extreme violence.
Real Cases: Defense with Sasumata
Some recent cases in Japan demonstrate the effectiveness of the Sasumata in risky situations. In Aichi, a 62-year-old man entered a school in Ichinomiya armed with a knife. Three teachers quickly used Sasumatas to subdue him and ensure the safety of the students.
A similar case occurred in Tokyo, where three teachers also used Sasumatas to contain an armed intruder. According to the school principal, all staff had received specific training to handle this type of situation, ensuring a quick and efficient response.
The use of the Sasumata requires preparation. Schools conduct training to ensure that teachers and staff know how to act quickly and accurately. The main technique is to use the fork to press down and immobilize the assailant's torso, keeping a safe distance.
