Inojin Yamanaka

is an Academy student and a member of Konohagakure's Yamanaka clan.

Personality
Inojin seems rather obedient and the most reasonable of the new generation of the Ino–Shika–Chō trio, as he, unlike his team-mates, insisted on going to training to learn the Ino–Shika–Chō techniques. When Chōchō refuses to go along and instead goes to eat dango with Anko, he calls her fat, which showcased that he may have inherited a penchant for insensitivity from his father, Sai. He also seems to have inherited the role of being the most motivated of the trio from his mother, Ino.

Appearance
Inojin has green eyes and blond shoulder-length hair which he keeps in a small ponytail allowing the rest to fall about his face — both traits featured heavily in his clan. He inherited his father's pale white skin colour. His attire is also similar to his father's: a black collarless suit with mesh armour underneath. In his backpack, he carries two items, the handles of which can be seen at each side. As customary of his clan, both of his ears are pierced by grey stud earrings.

Abilities
As a member of the Yamanaka clan and his generation's Ino—Shika—Chō, Inojin has begun learning the various mind-oriented techniques of his clan and collaboration techniques for his team respectively. He is also been taught the art-oriented techniques of his father. While not as elegant as his father's skill, Inojin is able to effectively bring life to his drawings for various purposes. In battle, Inojin wields a sword, indicating skills in kenjutsu.

Epilogue
After their sensei ends classes early due to the impending Five Kage Summit, Inojin tried to convince his team-mates Chōchō and Shikadai to go training with them. However, they both casually shirk their training opting to eat instead and claiming it was too troublesome respectively. Ultimately, he went to the training field alone, but was afraid to confront his upset mother and hid behind a tree instead contemplating how best to approach the situation.

Naruto Gaiden: The Seventh Hokage and the Scarlet Spring
Upon hearing that he and the rest of the class will be going through graduation exams in a week, Inojin was surprised how little some of his classmates cared about it. Later, Inojin continued his training under his father in artistic ninjutsu, noting that his father's style of drawing is so old-fashioned.

Boruto: Naruto the Movie
Inojin meets with Boruto Uzumaki and Shikadai to play video games together after they finish their missions for the day. When Boruto offers to give them his data to make the game easier, Inojin reacts with disappointment, along with Shikadai to find that Boruto had been cheating while they were playing. Later on, Inojin enters in the Chūnin Exams with Shikadai and Chōchō.

Trivia

 * According to the movie's light novel adaption, Inojin's role-playing character, when he plays with Shikadai and Boruto, is a white mage.
