I've heard Japanese people think this way of people who drink milk.

It so. Domino’s Japan has a corn & mayo pizza. Most pizza chains do.

It is so. Mayo is huge in Japan. Andrew Zimmermann did an episode on it, one of the few times he's struggled to eat something. https://www.travelchannel.com/shows/bizarre-foods/episodes/japan

Edit: Zimmern, not Zimmermann

Went to Asian market yesterday to pickup some stuff, and there's a whole section dedicated to mayonnaise.

They love their mayo.

Please don't correct this. It works great.

Edit: Helped the person with a good call on thier comment, only to be a target of whatever the hell they're imagining.

Canadian here. Nope, that shit can stay in Japan.

If you want to try it fine. But it's a hard pass for me.
