12-2-2016 Holding Katana

Holding the katana. December 2nd, 2016.

The katana is a weapon in Yandere Simulator.


In the game, the katana is found in the Headmaster's Office locked in a case, with an explanation for that in the Headmaster's Tapes.[1] YandereDev once stated that the katana could be something that the headmaster confiscated but never got rid of.[2]

The katana cannot be concealed in the player's inventory and is seen as suspicious, so if any student sees Yandere-chan holding the weapon, her reputation will be damaged by ten points at high School Atmosphere.

Yandere-chan cannot use a katana when fighting a Heroic student and will automatically lose, as the weapon is too unwieldy to use in close quarters.

As of the March 3rd, 2016 Build, Yandere-chan can put a katana inside a cello case or a trash can in order to conceal it.

Katana Animations

There are 4 killing animations for the katana, depending on Yandere-chan's level of sanity. The katana animations were shown in the video "Should Yandere Simulator be re-named?"

  • High Sanity: A diagonal slash through the student's stomach.
  • Medium Sanity: Two diagonal slashes through the student's stomach.
  • Low Sanity: She knocks the student down to the ground and repeatedly stabs them from above.
  • Stealth Kill: She covers the student's mouth and stabs them from behind.


  • As of the March 5th, 2016 Build, a mind slave cannot be given a katana.
  • Before the March 15th, 2016 Build, the katana killing animation was stabbing a student in the neck. It was not held over the shoulder either.
  • Yandere-chan holds the katana the same way as she holds the axe, baseball bat, the magical girl wand, and the shovel.
  • The Katana killing animation is the same as the fantasy sword, the knife blade, and the sword.
  • As of the June 21st, 2016 Build, there is a placeholder sound effect for the katana.
  • YandereDev plans to make the katana a one-of-a-kind item, so when it breaks, it stays broken.[3]
  • Kocho confiscated it from a delinquent in 1988.[4]


Is that a...katana? That better be a prop or something...
