Assassination Classroom Wiki

Nobuta Tanaka (田中 信太 Tanaka Nobuta) is a student in Class 3-D of Kunugigaoka Junior High School who is often seen with Chosuke Takada (Nobuta's friend).


In contrast to the lanky Chosuke Takada, Tanaka is thickly built with a round face. He has black spiked hair, narrow eyes, freckles on his face, and lightly tanned skin.


Just like Chosuke Takada, Tanaka is very disrespectful to Class 3-E as he takes what he says very lightly, casually threatening to "kill" Nagisa Shiota without thinking of the implications of his words. However, he will cowardly back away if he were to be intimidated, such as when he ran away from Nagisa upon being given a glimpse of the latter's bloodlust. He will also back off if he were to be confronted by someone better than him in any way.

Although the two used to be classmates in Class D, Tanaka constantly mocks Nagisa for being in Class 3-E.

Tanaka appears along side Takada in every appearance he makes, indicating that they are very close. They are so close that they have no qualms holding each other or sharing a two-person bicycle.

Their relationship appeared close enough to make the girls in their class suspect they were in a romantic relationship.[1]



  • The name Nobuta means "trust, believe" (信) (nobu) and "thick, big, great" (太) (ta). 
  • Nobuta's surname Tanaka means "field, rice paddy" (田) (ta) and "middle" (中) (naka), which literally means "dweller in the rice fields" altogether.


  • According to the Graduation Album [2], Tanaka ends up living together with Chosuke Takada as roommates.
  • Tanaka gets his first-ever girlfriend after attending his university’s welcoming party for new students. However, because he is so close to Takada, she asks him, “Between me and Takada-kun, who would you choose?"
  • It has become a custom of theirs for Takada to listen to Tanaka complain about his girlfriend while they bathe.
