Choji Akimichi is a childhood friend of Shikamaru Nara. Together with him Ino Yamanaka, and Asuma Sarutobi they make team 10. Choji has a love for food, his favorite being Korean barbecue, general snacks and sweets, and basically anything that is edible. His nigh-constant hunger is a constant annoyance for his teammates, as sating himself often comes before other necessities such as stealth and teamwork. Because of this, his teammates often use food against him, such as offering him food as a reward for accomplishing a task or simply using his favorite foods as a form of blackmail. Despite his open display for his love of food, Choji is very sensitive about his size and becomes highly agitated when somebody calls him "fat." Once called "fat," Choji's resolve to fight is elevated to new levels and he becomes much more hostile to his opponents than he would otherwise. Just as they use food against him, Choji's teammates use this personality trait against him as well. Should Choji be reluctant to fight, one of them need only comment on his size to spur him into combat form.

As an Akimichi, Choji's style of combat focuses on increasing his size. At the series' start he uses Multi-Size Technique to serve this purpose, reshaping him into a large, round form.
