Kohan Yamanaka

is a member of Konohagakure's Yamanaka Clan, as well as a shinobi in the Konoha Barrier Team.

Personality
Kohan is a very disciplined man, taking his job seriously. He dislikes tardiness and does not believe in coddling people. At the same time, he is a kind man who seeks to help where he can. He is also openly an admirer of Ino Yamanaka.

Appearance
Kohan is a tall man of fair complexion and pale blue eyes. He has hime-style blond hair reaching his mid-back that is tied in a high ponytail. He wears the latest Konohagakure shinobi attire, including high sandals, grey pants and long-sleeved shirt, and green flack jacket.

Abilities
As a trained member of the Yamanaka Clan, Kohan is implied to be well-versed in his clan's mind-oriented techniques. He is a skilled sensor, working alongside the Konoha Barrier Team. He is also a capable teacher of the skill.

New Era
Kohan took part of the trial run of Konohagakure's new, automated sensing system. He was partnered with fellow clansman Inojin, and tasked with apprehending mock intruders. He was surprised by Inojin's poor performance, who failed to apprehend a single target. Inojin asked him for pointers, which he did, drawing a comparison with their clan's hiden jutsu. During one of the tests, Inojin claimed to detect a strange chakra, with Kohan verified and confirmed to be a registered signature. Inojin insisted there was something off, and when Shikadai vouched for him, Kohan allowed them to investigate, eventually discovering an actual intruder and a loophole in the sensing system. He congratulated Ino on her son's discovery. She however admitted Inojin had little aptitude for sensing, and would have to find his own way.

Later, it was learned that shinobi data was being stolen from various villages. Kohan joined the effort to apprehend the thieves when reports came that they were in Konoha. Kohan later found Inojin and Chōchō Akimichi apprehending Jingo Kumano, a former Kumo-nin turned local ramen restaurant owner, for their mission. Kohan quickly cleared up the confusion, apologising for an error in Konoha's system for not recognising him as citizen of the village.
