Tantojutsu

Tantōjutsu (短刀術) is a Japanese term for a variety of traditional Japanese knife fighting systems that used the tantō (短刀), as a knife or dagger. Historically, many women used a version of the tantō, called the kaiken, for self-defense, but warrior women in pre-modern Japan learned one of the tantōjutsu arts to fight in battle.
