Itachi lived at a distance from others, observing people and evaluating various ideas, trying to fully understand them and not taking anything for granted. Because of his isolation, Itachi rarely got close to anyone, but this approach allowed him to think and act without prejudice, as well as evaluate things with an open mind. Itachi thought a lot about the nature of Shinobi, as well as about his native village, its origin and future. He speaks Japanese.
