Naruto becoming Hokage is not shown in Naruto Shippuden. After the war, the last episode of Naruto Shippuden ends with the marriage of Naruto and Hinata. So when does Naruto actually become Hokage?
Naruto becomes Hokage in an OVA named The Day Naruto becomes Hokage. In the Boruto anime, episode 18, it is shown in a flashback how Naruto ascends the throne as the 7th hokage. Hokage is someone who rules or takes care of his jurisdiction.
Naruto wanted to be Hokage so that he could get acknowledged by people. In his childhood, he was treated very badly by all except a few people like Iruka sensei. The journey of Naruto Uzumaki from a hated child to a hokage is really painful.
However, after fighting in the great Fourth Ninja War and defeating the enemies, Naruto became famous and gained respect not only from his villagers but across the entire shinobi world. As often said by Naruto that “I am gonna be Hokage, no matter what”. He finally proved it and attained the title.
