I sure hope that no one in Aomori Prefecture ever made a promise that was contingent on Nio Waterall (Niogataki) freezing over—such as, "Sure I'll pay you back—when Nio Falls freezes over."
Because that's exactly what happened this week.
Actually the freezing of the falls is known to happen occasionally—the last time was 3 years ago—and is said to be a sign of a bountiful harvest in the fall.

Yeah, I'd say it's a little cold today.
