The Yamato was huge. You should go see it sometime.
Bring a towel.
Reading this source I noted nine bomb hits, but I think what really got the ship was 7 plus torpedo hits on the port site. I am sure that was a damage control problem that there was no way to solve.
I bet for an aircraft carrier that hitting the island would render it inoperative.
