hago did get the forehead shinjuu seal symbol just after he started using his sp senjutsu (I know it was filler), so maybe hashirama's sm might be connected to that.. they do say the more chakra one has, the easier it is for one to learn it, and man, hashirama had tons of chakra.. enough chakra to say that bsm Naruto was just getting close to their edo chakra levels. so alive, his chakra was massive. and hago had even more. for hago's senjutsu training, it was like Naruto learnin rasengan.. probably not THAT hard.
