It's being called the "scariest commercial ever," because it is.

In fact, this just-released ad for Japanese tire retailer Autoway Tires is so scary, it's prefaced with a health warning and a liability disclaimer.

"Not for the faint of heart," warns the ad. "Please refrain from watching the content if any of the following applies to you: Have any mental or physical health concern and may have to see a doctor regularly."

Autoway goes on to caution viewers that it "shall not be liable for any injuries, illness, and damages claimed to be caused by watching the contents."

Still not sold on just how scary this ad is? Then turn up the volume, turn down the lights, and proceed.

You have been warned.
