Is it considered rude to ask for an ingredient to be left off of food in Japan?

I know that Japan could sometimes get upset if not all of the food was eaten in some places, and other stuff like that. So say i didn’t want mayo on my okonomiyaki, would they be personally offended by that? or is there a line where asking for no lettuce on my McDonalds burger is ok but not for the okonomiyaki... show more I know that Japan could sometimes get upset if not all of the food was eaten in some places, and other stuff like that.
