The naval ship Yamato wasn't much use in the end. It was too valuable to be put in harm's way until the end when it was sent on a suicide mission to try and interdict the landings on Mindanao. It was sunk by US divebombers and torpedo planes.
There is still debate over whether it was capable of firing a full broadside with those 18" main guns without turning turtle.
Japanese capital ships were less vulnerable to air attack than British ones but much more vulnerable than US ships especially the later ones which had vast numbers of small machine cannon able to put a hail of lead in the air.
