Do not try to cook popcorn in a pan using sweet cooking wine instead of cooking oil. Though the bottles look exactly the same here in Japan, one cooks down into a super-hero-strength, seemingly atomic-bomb-proof crust and it fuses directly to the bottom of the pan. The other doesn't.
Unless one wants to spend the next two days trying to remove said fused composition with a heavy-duty scrubber and feeble chemistry attempts of baking soda and boiling water, JUST DON’T DO IT.
My suggestion: before coming to Japan, learn the Kanji for cooking oil.
