Risotto in Italian cooking definitely uses buttoer. But, I already know what your reply will be: "Oh, that's Northern Italian cooking -- it doesn't count." Most normie readers don't care about that distinction.

Japanese izakayas frequently sell grilled items wrapped in foil that is swimming in butter. Again, I assume you will reply: "Oh, but that's not traditional Japanese cooking -- it doesn't count." Again, most normie readers don't care about that distinction.

Japanese cuisine absolutely does use butter, just not nearly as much as other cultures.
