The Kobu Jutsu (also known as Kobujutsu) is a weapon used by Tanya in Mortal Kombat: Deception and Mortal Kombat: Armageddon. It appears like a hybrid of two weapons: it has a Kama-like blade attached to a weapon body which is wielded like a Tonfa.
Tanya is still using her Kobu Jutsu in the new timeline; she is seen using them during the cutscenes of Mortal Kombat X and in her Kobu Jutsu variation, even using them in her fatality to pin down her victim. She also throws them in one brutality.
- In Deception, Kobu Jutsu's early name was Tonfas. The weapons behave in the same manner to Jax's Tonfas in Deadly Alliance.
- "Kobu Jutsu" derives from the Japanese word "Ko bujutsu" (古武術), literally meaning "Ancient Martial Art".
