I’ve used the “school closed” image to indicate that Kumamoto Gakuen University has cancelled classes scheduled for Monday (which is a holiday but, because the government requires universities to make sure that classes scheduled for each day of the week meet at least 15 times per semester, classes had been scheduled for tomorrow).

Kumamoto University also has classes scheduled for tomorrow but their web site still does not indicate whether or not classes will actually be held. Kumadai seems to have different cancellation criteria so it’s possible that they will hold classes even if other universities in town do not.
Kumamoto City has cancelled various events scheduled for today and tomorrow:
