Okonomiyaki
I’m not sure when mayonnaise started being served with okonomiyaki. If you go eat at an okonomiyaki shop now, your okonomiyaki comes with mayonnaise. If you buy okonomiyaki at your local convenience store, it comes with a pouch of mayonnaise.
Growing up in Kansai, a lot of our weekend lunches was okonomiyaki (and yakisoba too). When I visit my parents, my mom usually makes okonomiyaki, but no mayonnaise in the Kimura residence (^^) Just lots of katsuobushi (dried bonito flakes) and aonori (powdered green seaweed) on top of the sauce.
