It’s off the coast so you may have to worry about tsunami.
Incidentally, we have a spare bedroom here in my place if you and yours need an evac locale in the future. It’s actually in Kugayama, so we are safe from any flooding danger.
I am pretty much on the highest ground (that I know of) in Chiba City... I think/hope that I won’t have to worry, unless there is a massive tsunami from the Tokyo Bay coast..
Thank you very much though... Stay safe and stay in touch with us!
