The Blowgun was a hollow tube, usually bamboo, about 20 inches long. The Japanese blowgun had no mouthpiece; the user wrapped their lips around the pipe. The darts were usually tipped with tetrodotoxin taken from the puffer fish.
According to the show; the Blowgun had a precise effective range of about 5-10 meters; depending on the skill of the warrior and the length of the tube.
Because the Ninja blowgun was shorter than other blowguns, it had a shorter effective range. Because of this, it was typically fired from a concealed location, using the poison to kill the opponent while the Ninja made his getaway. Many schools of Ninjitsu, such as the Togakure-ryu, are dedicated to the art of using the blowgun alone.
The blowgun could also be used as an improvised straw or snorkel to help the Ninja survive in the wild.
