Metsubushi

Metsubushi was a powdered irritant. When thrown in the eyes, it blurred vision considerably and caused extreme watering. It also burned the nasal passages, although not enough to cause any permanent damage. Metsubushi was often carried by yoriki or doshin to disable rowdy samurai so that they could be disarmed or taken into custody. It was also often kept handy at Geisha houses in the event that a customer got out of hand. Metsubushi must be deployed either by hand or through a weapon such as the Machi-Kanshisha.
