Background
During the Nine-Tails' Attack on Konoha, Chōza and his team-mates assisted in the village's defence. A few years later, Chōza learned that Chōji was treated as an outcast because of his weight and that he was being told by other children that the Akimichi were useless ninja. Chōza told him that one day, he would have true friends that would realize that wasn't the true Chōji. Chōza is the head of the Akimichi clan, and was part of an "Ino-Shika-Chō Trio" alongside Shikaku Nara and Inoichi Yamanaka, his name being the Chō part of the group name.

He wears a samurai like outfit which entails a black suit completed with armour that has the kanji for on it. He also wears a rope belt, hand guards, and instead of a forehead protector, wears a piece of cloth tied around his head. Whenever he uses the Multi-Size Technique two markings appear under his eyes; these markings disappear when he reverts to his normal size.

Personality
He is a gentle and caring man with seemingly great wisdom and understanding of the world, and has deep love for his son, Chōji. Like the rest of his clan, he has a large appetite, and is prone to eat everything on an entire page on the menu.

Abilities
Like his son and the rest of his clan, Chōza uses the special technique that allows him to change calories into chakra. As the leader of his clan, it is highly logical that he is skilled in all of his clan's secret techniques. He was able to provide assistance to Kakashi Hatake against Deva Path, as well as confident enough to fight both the Summoning: Impure World Resurrection of Dan and Asuma Sarutobi, both elite Jōnin at the same time. He also uses a Bō in battle that has the ability to lengthen in proportion to him when he grows in size.

Akimichi Ninjutsu
He has been seen using the Multi-Size Technique, the Human Bullet Tank and the Partial Multi-Size Technique, which all revolve around the clan's special ability to increase the size of their various body parts.

Chūnin Exam Arc
He made his official appearance during the Chūnin Exam Festival, sitting alongside his former team-mates who were talking about the fact that Inoichi had a daughter, and how troublesome that was, according to Shikaku, while Chōza was looking at the menu only to order everything on the page that he was looking at. When Shikamaru came to pick up his father, Chōza invited him to come and eat with them.

Invasion of Konoha Arc
He made his next appearance during the end of the Konoha Invasion arc, using the Multi-Size Technique to trample some Otogakure Shinobi, and later met up with Inoichi and Shikaku to reunite the original Ino-Shika-Chō Trio.

Sasuke Retrieval Arc

Invasion of Pain Arc
He and Chōji, along with a third Unnamed Akimichi Member and other reinforcements, were seen during Pain's invasion, helping Kakashi by crushing the Asura Path. During a failed attempt to defeat the Deva Path with Kakashi and Chōji, Chōza was seemingly killed while protecting Chōji from Shinra Tensei. Later it was discovered by Tsunade, that Chōza was still alive but needed to be brought to the hospital immediately, which caused Chōji to cry in joy.

Shinobi World War Arc
When the war begins, Chōza is placed in the First Division of the Allied Shinobi Forces along with Tenten, telling her that Darui was their commander. He is the only person not to wear a proper ninja village's uniform for some reason. After their unit comes in contact with the enemy, Chōza faces off against the revived Asuma Sarutobi and Dan Katō, the latter noting on how much Chōza had grown, with Chōza replying that he was about to grow a lot more.

Later, Chōza fights in his gigantic form with his staff. Soon after Kinkaku transforms, Chōza blocks a swing from Kinkaku's tail, and wonders if he's a jinchūriki. After Kinkaku is sealed Chōza beams with pride at Chōji. Later as continues his fight against Dan who warns Chōza and the other members of the First Division to trap him with the Four Violet Flames Battle Encampment before he uses his Spirit Transformation Technique; Chōza replies that is easier said than done when Dan is the opponent.

As Chōji becomes frightened during the war, he tells his son to look around him to realise that they were in a war and that everyone was fighting for their lives. Later he protects them from Asuma's Fire Release: Ash Pile Burning by throwing his massive form in front of them to block the attack. As Chōji still can't bring himself to fight his former teacher, Chōza reminds him of the oath he made as the 16th head of the Akimichi clan. He is surprised when Chōji is able to create butterfly wings on his back without taking the Three Coloured Pills. As Shikamaru and Ino ask if Chōji will be all-right in that state he tells them yes as Chōji had finally mastered the Calorie Control of the clan. He then apologizes to them for Chōji early hesitant nature and tells them that's all over now. He then states that Chōji was finally worthy of being the 16th head of the clan. Having the utmost confidence in his son now he tells them that's he leaving. He later seen in apparent combat once again with Dan, watching on with surprise as Chōji spreads his massive wings across the battlefield.
