How could japan have made that powerplant tsunami proof? Put the emergency generators on a pontoon or on a inland moumountain?

put some generators on roof. Generator placement in Jp was based on BWRs placement in US - underground, which is sane considering tornados and stuff. But it wasnt adapted there

The same way anyone else avoids flooding: by building it on slightly higher ground.
