Overview: The ninja are said to have been proficient in the use of gunpowder long before guns were brought to Japan, and to have invented over 230 uses for it. In this episode, we'll introduce the toribikata, a weapon similar to a flamethrower that was used to fend off several attackers at once, and the hyakuraijyu, which created chaos by emitting a noise similar to a volley of gunshots. We'll also recreate the grenade-like hourokuhiya to determine its strength, and the daikokuhiya, a weapon frequently mentioned in the ninja training text Bansenshukai, to learn about how it was actually used.
