The only people confirmed to have seen Kakashi Hatake's face in the Naruto universe are:
- Obito Uchiha: Obito was Kakashi's childhood friend and teammate. He witnessed Kakashi's face before the tragic accident that cost him his left eye.
- Rin Nohara: Rin was also Kakashi's teammate. She saw his face before the accident.
- The Fourth Hokage (Minato Namikaze): Minato was Kakashi's sensei and the Fourth Hokage. He likely saw Kakashi's face at some point during their training or missions.
- Kakashi himself: Kakashi obviously sees his own face every day.
- Anyone who sees him while he is using the Sharingan: Kakashi's Sharingan can be used to copy jutsu, but it also reveals the user's face. Anyone who sees him using this technique would see his face.
While it is possible that other characters have seen Kakashi's face at some point, these are the only instances explicitly confirmed in the Naruto canon.
