Flying Thunder God Kunai (飛雷神クナイ, Hiraishin Kunai) are custom-made kunai (特注クナイ, tokuchū kunai) and signature tools of Minato Namikaze, who uses them in conjunction with his Space–Time Ninjutsu: the Flying Thunder God Technique. They differ from a standard kunai in that they have three blades instead of one and the handle (which is thicker than normal) serves as the "marker" for Minato's teleportation ability. Minato also said that these blades are a bit heavier than a normal kunai.[1] Their prongs also make them more deadly in melee fighting.

Minato gave one of these kunai to his pupil, Kakashi Hatake, as a celebratory gift for his promotion to jōnin as well as to be able to teleport to his team at any time as long as they had the kunai in their possession.[1][2] During the Third Shinobi World War, in the battle between Konohagakure and Iwagakure, the ninja from the former threw these kunai behind enemy lines which allowed Minato to instantly teleport to the various locations and slay the opposing shinobi, while at the same time making it difficult for the enemy to predict where he would teleport next.[3] He also kept several of these blades at his safe houses, so he could teleport there quickly when necessary.[4]

Utilised Techniques[]

In Other Media[]

In Naruto Shippūden the Movie: The Lost Tower, Minato placed one of these kunai over the source of the Ryūmyaku to seal it. Mukade managed to remove the kunai by absorbing the seal, which also triggered a huge backlash of energy that propelled him backwards in time by 20 years, and Naruto Uzumaki and Yamato by 14 years.
