Inoichi Yamanaka

was a jōnin from Konohagakure, and, alongside Shikaku Nara and Chōza Akimichi, was a part of an Ino–Shika–Chō trio. He was also a member of the Konohagakure Intelligence Division.

Background
In the anime, nearing the end of the Third Shinobi World War, his team was assigned to deliver a request for a peace treaty between the Konoha and Iwa. Anticipating the Iwa shinobi to turn hostile, the meeting was strategically held at the borderline of the Land of Wind, knowing that the Fourth Kazekage would oversee the meeting should a battle breakout on his own land. During the Nine-Tails' attack on Konoha, Inoichi and his team-mates assisted in the village's defence.

Personality
From what has been seen of Inoichi throughout the series, he had a calm and perceptive nature, generally staying calm under pressure. He was also very analytical being able to put together the information he got from his interrogation to aid Shizune in uncovering the secret behind the Six Paths of Pain. He has also been described as having an indulgent and gentlemanly disposition.

Inoichi loved his daughter Ino very much. This sometimes lead to him indulging her a great deal but nonetheless he was proud of her. The bonds that she has with her friends, as well as her clan's ninjutsu prowess, stating before his death that she has truly blossomed to reflect the meaning of the violet flower that he raised her to symbolise.

Appearance
Inoichi had long blond hair reaching into his back, which he wore spiky on top and ending in a long ponytail, blue-green eyes and strong facial features, which included a well defined jaw line. In Part I, Inoichi was seen wearing the standard flak jacket over a black outfit, complete with hand-guards, forehead protector and a sleeveless red haori. In Part II, he wore the standard outfit of the Konoha Interrogation Unit, complete with a long black overcoat. During the Fourth Shinobi World War he donned the standard uniform of the Konohagakure shinobi.

Abilities
Inoichi, who is presumably the head of the Yamanaka clan, has shown himself to be a highly capable shinobi.

Yamanaka Clan Techniques
He was well-versed in all of his clan's secret techniques as witnessed during the Konoha Crush where Inoichi skilfully performed the Mind Body Disturbance Technique, causing the invaders he encountered to fight against their own allies. The anime showed that he was also able to use an advanced version of the technique which manipulates the mind of several enemies at once.

He has also shown the ability to communicate telepathically with other people. His skill with telepathic communication was such that he contacted and relayed a message to the entire Allied Shinobi Forces, despite its vast size for twenty seconds even though he stated he could only do it for ten, suffering only a nosebleed and fatigue.

Mind Reading Techniques and Sensory Perception
Further proof of his skills was shown from his status as an interrogator in the Konoha Torture and Interrogation Force during Pain's assault on Konoha where he was able to skilfully probe the mind of one Pain's Amegakure loyalist and go through an entire days worth of his memories in mere seconds with the aid of a device, even though Pain had set up mental blocks and traps in the shinobi's head.

His abilities had also been praised by others such as Aoba Yamashiro, who while attempting to interrogate Kisame Hoshigaki, stated that he was not as skilled as Inoichi in this area, and Tenga of Kumogakure who was greatly looking forward to working under his command. He was also skilled at tracking targets through their chakra trail, as long as the target's chakra signature stays the same. Alongside Ao from Kirigakure, he could create a wide-ranged detection type barrier big enough to cover all battlefields during the Fourth Shinobi World War.

Chūnin Exams
Inoichi first appeared in the anime alongside his former team-mates during the Chūnin Exam festivals. They were sitting in a bar where Inoichi was being teased for having a daughter instead of a son.

Konoha Crush
He appeared again during the Konoha Crush, protecting the village together with Shikaku Nara and Chōza Akimichi. He uses the Mind Body Disturbance Technique to cause the invading shinobi to fight amongst themselves. Inoichi then says fighting alongside his team-mates Chōza and Shikaku reminded him of old times when they were renown across the nations. Chōza then remarks that they still were.

Pain's Assault
When Ibiki Morino proved unable to learn anything about Pain from Yūdachi, he called on Inoichi for assistance. He probed Yūdachi's mind, rapidly going through his memories before arriving at the revelation that Pain had requested of Yūdachi: dead bodies. Before he could think further on this, Ino arrived to inform him of Pain's attack on Konoha, and the village was soon afterwards destroyed. Shizune was killed in the chaos by the Human Path and, using the information Shizune had learned before her death, Inoichi realised that Pain was animating dead bodies in a manner similar to his own clan's mental manipulation techniques, thereby meaning the true Pain was in a remote location somewhere relatively close by.

While looking for Pain's real body along with Shikaku and a shinobi from the Hyūga clan, they ran into Naruto Uzumaki. Inoichi asked if Naruto had defeated Pain, to which Naruto answered that it didn't matter and stated that he had found Pain's true body while in Sage Mode. He asked them not to follow him, as he wanted to talk to Pain alone. Inoichi stated angrily that talking didn't solve anything, but, after a brief argument, Shikaku told Inoichi to just let Naruto go, to which Inoichi hesitantly agreed. Inoichi along with the rest of the village, were overjoyed at Naruto's return to the village.

Past Arc: The Locus of Konoha
Inoichi is placed in charge of interrogating Hanare after she was captured and brought to Konohagakure. After seeing a memory of Kakashi Hatake as a child in her thoughts, he sends her over to him and see if he remembers her as their other methods of interrogation so far had failed.

Fourth Shinobi World War: Countdown
In the anime, Inoichi is seen attending the war council meeting that Tsunade calls alongside Shikaku. He later attends a private meeting that Tsunade calls in her temporary office as they discuss the impending war.

Fourth Shinobi World War: Confrontation
Inoichi was placed in charge of the Intelligence Division. When Aoba Yamashiro returned from his mission, Inoichi questioned him about his time on the Island Turtle stating that it seemed as though they had a rough time. His first act within the war, was to set up a barrier with Ao with which the Sensor Division could use to monitor the battlefields from headquarters.

He later relayed new information to the members of his division in the fields about the enemy forces travelling underground. After the Alliance realised that the First Division was soon going to be overwhelmed by the enemies' forces, Inoichi relayed the new battle strategy as created by Shikaku to the divisions. He then reported that Shizune had also split up her division equally in order to better attend to the wounded shinobi on each battlefield.

When headquarters needed to get in contact with Darui, Inoichi used a variant of his telepathy by placing his hand on Shikaku's forehead but told him he could not hold the connection for long. Nevertheless, this allows Shikaku himself to telepathically contact Darui, Ino, Shikamaru and Chōji, where he told them of his strategy to seal Kinkaku. After Kinkaku was sealed, Inoichi praised Ino's uses of the Mind Body Switch Technique as her use and release of the technique had increased greatly.

As the night dragged on, Inoichi received reports from multiple divisions that shinobi from the Alliance were being assassinated and that they could not find the enemy. After being asked by Shikaku what the corpses look like, he reports that they all died from external wounds and not from covert methods like poisoning. After receiving a report from the Logistical Support and Medical Division it was revealed that it was in fact members of White Zetsu Army who had transformed into shinobi from the alliance and were killing other shinobi and causing chaos.

After Naruto and B were allowed to head to battlefield by A and Tsunade, Inoichi once again used his telepathy to allow Shikaku to converse with the two jinchūriki. He is later contacted by Dodai who asks him to allow Naruto to talk to B and the Eight-Tails. Inoichi then asks Naruto how comes he wasn't with B before patching him through.

Later, in the anime, the Sound Four are also summoned to the battlefield. After Neji, Shikamaru, Kiba, and Chōji seemingly defeat them, the Sound Four and Leaf ninja are struck by a strange technique that has left them in a comatose state. After learning the truth of the technique, that it removes the victims soul and transports it to another location, he explains it can be dispelled like genjutsu, by pouring chakra into the actual technique. However, it has a seal that prevents even Inoichi, equipped with special enhancement tools, from being able to detect or communicate with them. Later, Naruto contacted Inoichi to explain the situation, making Naruto rush to his friends aid. Eventually, Naruto found the barrier and destroyed it, allowing Inoichi to locate Shikamaru and the others and dispel the technique to restore them.

Later, after a tremor was felt all the way at headquarters, Inoichi reported that it was due to a meteorite falling from the sky where the Fourth Division was located. He later facilitated Shikaku's contact with Genma and the Hokage Guard Platoon, instructing them to transport Mei Terumī to the front lines using the Flying Thunder God Technique. After headquarters received intelligence about the situation on the battlefield with Naruto, B and Tobi, Shikaku asked Inoichi to relay a message to the entire Allied Shinobi Forces in fifteen seconds. Though the other members of the Intelligence Division protested, stating it would put too great a strain on him, Inoichi told Shikaku that what he was asking was ridiculous and he would only give him ten seconds. Contacting the entire alliance, he relayed the message and spurred on the troops to aid Naruto and B. Suffering a nosebleed afterwards, a fatigued Inoichi stated that it seemed he wasn't good at speeches after all and ended up taking twenty seconds instead of ten and apologised.

Fourth Shinobi World War: Climax
Later, when the Sensing Water Sphere in HQ became distorted, Inoichi hastily followed through with Shikaku's order to check out the situation. After Shikaku had formulated a strategy during the time Naruto used to chide the opposition, Inoichi enabled Shikaku to communicate this to the entire Alliance. Inoichi later coordinated the various attacks as they attacked Madara, Obito, and the Ten-Tails. As the Ten-Tails reached maturity, Inoichi briefly connected Shikaku with Kakashi until the beast began to attack. The Ten-Tails fired a barrage of Tailed Beast Balls, destroying many locations. This lead Inoichi to wonder whether or not they were attacking the civilians until it is realised that they were aiming for HQ. Knowing there was no escape, Shikaku has Inoichi allow him to give out one last strategy to the Allied Shinobi Forces. Before being killed once the Tailed Beast Ball destroys HQ, Inoichi telepathically said his farewell to Ino, stating how proud of her he is and that he would always be watching over her.

Legacy
Leaving behind a quietly understated legacy, Inoichi was someone that many shinobi in the field of intelligence looked up to greatly because of his renown. For those who were able to witness his skills in person, they were always left in awe, and would aspire to attain his level of skill. Konoha, on a whole, benefited greatly from these skills as even the booby-trapped minds of those unwilling participants stood no chance against his prowess. The shinobi world at large would later come to heavily depend on these skills during the Fourth Shinobi World War where he was responsible for receiving and dispensing crucial information to and from HQ. Above his duties, however, Inoichi shared a close bond with his daughter whom he loved dearly. This would most often translate into him overindulging her, but despite this, Inoichi was proud of his daughter's growth, not only as a kunoichi, but as a person who protected her friends. In this, Inoichi was content that his daughter had truly grown to reflect the meaning of their clan flower symbol: the bush clover.

Years after his death, he would posthumously gain a grandson, Inojin, when his daughter married Sai.

Naruto the Movie: Blood Prison
During Naruto's flashback to the members of the village when he was gathering natural energy to enter Sage Mode, Inoichi can be seen amongst the villagers.
