Chōji was born into the Akimichi clan, and is slated to become the Sixteenth Head of the Akimichi after his father, Chōza. Though sensitive about his weight, Chōji is nevertheless dedicated to his friends, especially in Team Asuma. Chōji is a very kind, polite, and caring person. These characteristics are said to be his greatest strength by both his father Chōza and his former teacher Asuma Sarutobi while his greatest weakness was his lack of self-confidence. He is easily motivated by the prospect of food, and becomes highly agitated when somebody calls him "fat" (he refers to himself as "big-boned", "chubby") Asuma would say that he is just "pleasantly plump". However, he does not hide his love for food and his near constant hunger is also an annoyance to his teammates, as eating often comes before other necessities such as stealth and teamwork. Food can also make him over-react about silly things, such as who gets the last chip, or when Akamaru tried to take his chips, and he refuses to let anyone else eat the last chip in the bag, even in battle-situation. Chōji also tends to eat a lot when he's angry. Since Part II of the series, however, his eating habits are more controlled and no longer interfere with his duties as a shinobi. Chōji has a long-standing friendship with Shikamaru. The two have complete trust in each other, with Shikamaru being one of the few people to look past Chōji's lack of athleticism, and see that he had a kind heart; recognising Chōji's true strength.
