This weapon uses air pressure to shoot the arrow, which is loaded into a blowpipe.
Arrows are made of metal needles, as well as stone, bamboo, and wood.
Bamboo, animal fur, bark, and paper were used for the cone-shaped part called the wind receiver.
Blowguns are used as weapons all over the world, and are more portable and quieter than bows and arrows.
Even today, special forces sometimes use them.
A longer blowpipe improves accuracy.
Because the arrows are small, they are less likely to be blocked by plants.
When used in combination with poison, their power increases.
In Japan, they are often thought of as being used by ninjas, but no written records have been found indicating that they were actually used, so the actual situation is unknown.
However, during the Edo period, it seems that they were widely enjoyed as a shooting game by everyone from commoners to feudal lords.
