Kirk here. I complained about EVERYONE getting repeated midnight warnings and reports that gave the impression that everyone had to evacuate. But, it’s also true that a lot of people were put in harm’s way and quite a few suffered significant damage, particularly in the Tamana area.
If you are one of those whose property was damaged, you may be able to get compensation. Check out this page from the prefecture.

The page also says that you may be able to receive compensation if your car was damaged.
