Hashirama. He trained hiruzen,one of the strongest kages ever. Hiruzen then raised oro,j man and tsunade,the legendary sannin. Oro trained sasuke ,on of the gods on the world. Tsunade trained sakura and made her the best medic non out of nothing. J man.... He trained minato,the hokage and genius,trained nagato,yahiko and konan,and naruto. So if u think about it,it was hashi trained all of hokages.
