Question: are the hokage the strongest kages?
Answer: Hashirama Senju was the First Hokage of Konohagakure and one of the strongest to ever live. He was the first-ever Kage to be elected and was thus an example for many. Hashirama Senju remained unsurpassed for quite some time and even by the end of the series only a few shinobi managed to get past his level.
