The user converts chakra into timber under the ground and lets it grow rapidly while forming it into a wooden prison. The size of the prison is based on the user's imagination. From an insect cage to a great prison, one can make it into whatever they want by regulating the amount of chakra used. The timber itself is treated with a chakra coating, making its destruction extremely difficult. During war, it has the great ability to detain prisoners, but it can also be used as a disciplinary measure for quarrelling subordinates.


  • In Naruto the Movie: Blood Prison, when Yamato used this technique to imprison Naruto, parts of the prison extended into the interior to serve as additional shackles to bind Naruto, and Tsunade placed a sealing tag onto the prison, which, when removed, caused the prison to disappear similar to recalling a summon.
