Avoiding Trans Fats?

Do you guys know any tips for identifying and/or avoiding trans fats in packaged foods in Japan or how widespread the use is? Any obvious ones to avoid or text to look out for on the label? ​Coming from U.S. where they basically eliminated all trans fats from things you normally buy, and nutrition labels that are detailed enough and easy to confirm ingredients, I don't know how to identify the same on Japan's food labels, it sounds like they still use trans fats in some ​packaged foods? I cook most dinner from scratch but lunches​ I love to get the frozen noodles like tan tan and champon and the richna/ajinomoto Bolognese and carbonara ones. Also love frozen gyoza 😄 ​thank you for any advice!
