He is father of Chōji Akimichi and former team-mate of Shikaku Nara and Inoichi Yamanaka. Together they were the previous Ino-Shika-Chō trio. During the Nine-Tails' Attack on Konoha, Chōza and his teammates assisted in the village's defense. A few years later, Chōza learned that Chōji was treated as an outcast because of his weight and the belief that 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 the first "Ino-Shika-Chō Trio" alongside Shikaku Nara and Inoichi Yamanaka, his name being the Chō part of the group name. 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. 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 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. He is also skilled at using a staff in combat, which seems to also grow when he uses the Multi-Size Technique.
