senbon

Senbon is a term that can refer to several different things, most notably a unit of currency and a fictional technique.

In the context of currency, Senbon (千本) is a Japanese word meaning "one thousand needles" or "one thousand branches." Historically, it was used as a unit of currency in Japan, particularly during the Edo period. Its value fluctuated over time and was often used as a subordinate currency to larger denominations. While no longer in common use, the term can still appear in historical contexts or as a thematic element in Japanese culture.

In popular fiction, particularly in anime and manga, Senbon is often depicted as a type of projectile weapon, resembling small, sharp needles. These needles are typically thrown with great speed and accuracy by skilled practitioners. They can be used for offense, to inflict damage, or for utility purposes, such as pinning opponents or creating diversions. The effectiveness and specific properties of senbon in these fictional settings vary greatly depending on the narrative and the abilities of the characters wielding them. The concept draws from the historical use of similar small projectiles in traditional Japanese warfare.
