More on the yum yum debacle.
Sure, mayo exists in Japanese cooking. Or at least as a nice swirly decoration on the greatest sushi roll ever.
If you people SAW what the woman across from me was DOING with the yum yum, you'd be horrified and tweaked as well. I'm talking POURING it over rice, vegetable, and meat. I have to think this is NOT what the gods of Japanese chefery (I made that word up. Suck it) intended as the usage of this condiment.
If they ("they" being Morimoto on Iron Chef when he defeated Bobby Flay) get pissy when someone jumps on a cutting board, I have to think they would throw a samurai sword at your head if the mayo was poured over so excessively.
