The Hokage is a prestigious title passed on to Konohagakure's strongest, and most capable shinobi in Naruto. Being the first shinobi village in existence, Konoha was also the first to elect a Kage, which ultimately led to the creation of the shinobi village system throughout the five great nations.
Ever since Konoha was created, it has always had a powerful Hokage at its helm, and it's their duty to protect the people and defend them from incoming threats. Konoha has seen seven Kage rise to this position so far. Here are all the seven Hokage of Konoha ranked according to their strength in Naruto.
7 Kakashi Hatake
Once famed as the Copy Ninja, Kakashi Hatake was one of Konoha's elite Jonin who went on to become the Sixth Hokage of the village. Thanks to his extremely high level of skill, Kakashi had always risen through the ranks quickly. He was made a Jonin by the age of thirteen, and as such, was always headed for greatness. In the Fourth Great Ninja War, Kakashi did enough to earn the spot of Hokage, although, despite that, he is nowhere near the strongest in the series.
This is primarily because Kakashi, as a Hokage, had lost his Sharingan. While his chakra levels were better, as a result, it also meant that Kakashi lost the reason why he was special. During his time as the Hokage of Konoha, Kakashi was not the strongest in the village, with the likes of Naruto, Sakura, and Sasuke all being levels above him.
6 Tsunade Senju
Taking the position of Hokage after Hiruzen Sarutobi's passing, Tsunade Senju was chosen as the Fifth Hokage of Konohagakure. Being one of Hiruzen's students, it isn't hard to imagine that she was strong as well. Together, with Orochimaru and Jiraiya, Tsunade formed the Legendary Sannin of Konoha who were famous across the land. As one of the Sannin, her fighting capabilities were immense in the series, and she was capable of fighting against characters like Madara to some extent.
Tsunade's specialty was her 'Chakra Enhanced Strength' Jutsu, and other than that, she could also use the Forbidden Jutsu of Byakugou. In the Five Kage vs Madara fight, she was perhaps the most active Kage on the battlefield, both fighting the enemy, and healing all of those around her. Despite that, Tsunade takes the number 6 spot on the list.
5 Tobirama Senju
Tobirama Senju was the second Hokage of Konoha and he succeeded his brother, Hashirama, to the position. Possessing a high intellect, Tobirama set up the Konoha Academy and the Police Force. He led his village in the First Great Ninja War, where he ended up losing his life to Kinkaku and Ginkaku.
As a shinobi, his skills were immense. He was a water-style master, yet proficient in all five nature transformations. Apart from that, Tobirama also had access to a lot of Forbidden Ninjutsu, some of which he invented himself. It goes without saying that he was one of Konoha's strongest ninjas of all time in the Naruto series.
4 Minato Namikaze
Minato Namikaze, also known as the Yellow Flash, was Konohagakure's Fourth Hokage. In his generation, Minato possessed skills second to none. In the Third Great Ninja War, he defeated thousands of enemies all alone and was partly responsible for the peace that followed after.
Minato knew three nature transformations, but his skills lied in his speed which was great enough to take even the Fourth Raikage by surprise. As Konoha's Fourth Hokage, he was strong enough to fight Obito and Kurama at once, all the while protecting the village simultaneously, which definitely says a lot about his capabilities as a Kage.
3 Hiruzen Sarutobi
The Third Hokage of Konoha, Hiruzen Sarutobi was renowned as 'The Professor' and the 'God of Shinobi'. It is said that in his prime, Hiruzen was stronger than ever other Hokage who came before him, and yes, that includes Hashirama Senju. Unfortunately, a glimpse of his skills in his prime was never delivered. Despite this, even as an old man, Hiruzen was extremely powerful! Despite being way over 60 years in age, he showed his massive power by fighting Orochimaru, Edo Hashirama, and Edo Tobirama all on his own, which often goes unnoticed.
Hiruzen earned the title of 'The Professor' from having knowledge about all that Jutsu that exist in Konohagakure. His Will of Fire urged him to call every citizen in the village his family, and it was his thinking that molded Naruto's thinking as the Hokage of the village.
2 Hashirama Senju
Hashirama Senju was the First Hokage of Konoha, and one of the strongest characters in the entire series. Being the First Hokage, he possessed the strength that was enough to counter Madara Uchiha in combat. Hashirama Senju was a master of all five nature transformations, but his specialty was his Wood Release Kekkei Genkai. Using this power, he was capable enough to combat both Madara Uchiha and the Nine-Tails at the same time, which is extremely impressive, to say the least.
Hashirama's powers were further enhanced by his Sage Mode, which is what made him the strongest shinobi of his generation. His Sage Mode, when combined with his Wood Release ninjutsu, made him unstoppable. Although Hashirama was a fantastic shinobi, he certainly wasn't the strongest.
1 Naruto Uzumaki
The Seventh Hokage, Naruto Uzumaki is the current leader of Konoha and also the strongest of all the Kage. Although Naruto's start was shaky, over the years, he has mastered various Jutsu and overcome his weaknesses with sheer hard work. Thanks to his various abilities, such as the Sage Mode, the power of Kurama, and the Six Paths powers, Naruto is deemed as the strongest ninja to ever exist, with the only one capable of rivaling him being Sasuke Uchiha.
During the Fourth Great Ninja War, Naruto received half of the Sage of Six Paths' powers, along with the chakra of the remaining Tailed Beasts, making him a pseudo-ten-tails Jinchūriki. He's only gotten stronger over the years, and right now, he's grown to a level where he can rival the Gods of the Narutoverse, such as Momoshiki Otsutsuki. Undoubtedly, Naruto is the strongest Hokage to have ever lived, and it is unlikely that anyone will ever surpass him.
