Konoha Barrier Team

Konoha's Barrier Team (結界班, Kekkai-Han ) is a facility located inside the Hokage Residence in charge of detecting and intercepting intruders that cross the Sensing Barrier surrounding Konohagakure . The team is currently led by members of the Yamanaka Clan .

## Background [ ]

During the era of the Fifth Hokage , the Barrier Team was led by Kakoi, a sensor-type shinobi from Konoha, with the assistance of other Shinto priests . When the chakra signature of someone unrelated to Konoha enters the barrier, the Sensing Water Sphere connected to the Sensing Barrier around the village ripples around the exact area the intruder has trespassed.

Before Pain's Invasion, it consisted of a big room with two floors. On the upper floor was the area for the Interception Team and the lower floor was the area for the Detection Team. In the center of the room was a basin with streams of water supporting the Sensing Water Sphere.

After the Fourth Shinobi World War , the Barrier Team implemented a much stronger Sensing Barrier to compensate for the disaster that Pain's infiltration had caused; and started using the Mind Transmission Device for instant telepathy.

## New Era [ ]

By the era of the Seventh Hokage , the Barrier Team was completely modernized into a completely automated sensing system by the Scientific Ninja Tools Team and Ino Yamanaka 's lead. The Sensing Water Sphere has been replaced by a Scientific Ninja Tools sensing sphere that sends an automatic alarm to the monitors guarding the Sensing Barrier. The team also use the Mind Transmission Device to inform of the intruder telepathically. The new system governed by an official clause that prohibits private telepathic links between people without the consent and regulation of the staff .

Despite being an automated system, the Barrier Team is unable to detect ninja that mask their chakra or are located away from the limits of the Sensing Barrier . Likewise, the team is also unable to detect clones or ninja that use techniques that imitate chakra signatures. Due to this condition, Koji Kashin was able to infiltrate the village due to being a clone of Jiraiya . In the anime, Hyōi Yorishiro used a transformation jutsu and impersonated a village's carpenter by copying his chakra signature, thus becoming undetectable for the Barrier Team. However, Inojin was able to sense the disturbances in his chakra and apprehended him, which later led to further adjustments in the Sensing Barrier .

## Teams [ ]

- Detection Team: It was previously formed by Kakoi and two other sensor-types. This team is now completely automated.
- Interception Team: It was previously formed by five members. This team has been officially disolved, instead alerting Sasuke Uchiha and Naruto Uzumaki of intruders to investigate themselves .

## Trivia [ ]

- The Barrier Team debuted in chapter 415 of Naruto and it's described as Barrier Team (結界班, Kekkai-Han ) by Masashi Kishimoto in the Fourth databook. However, Ukyō Kodachi changed the name to Sensory Unit (感知部隊, Kanchi-Butai ) prompting the anime team to keep changing its name from Sensing Unit to Barrier Team periodically.
- According to Pain, Itachi Uchiha and other ANBU members use a secret technique to allow other shinobi to enter the village without being detected .
