|Rōmaji||Karada seichō gijutsu|
|Literal English||Body Growth Technique|
This technique was created by Kaien, through the help of lizards. With lizards, when their tails are cut off, they grow back, so Kaien ran experiments on how they grow their tails back. Kaien used multiple test subjects, until he did it on himself, already being an experiment of the Jashinist, it worked on him.
By concentrating chakra on the certain part of your body that is gone, the user can grow it back rapidly. Bone, muscles, tissue, even some organs can be rebuilt through this technique.
