I’m not talking about the “typical” junk food (like KFC or McDonalds), instead it’s more on certain aspects of Japanese cuisine being carb heavy or features fried items such as: ramen, agepan, karage, tempura, gyudon, tonkatsu, yakitori, etc. I mean, can ramen or gyudon bowls still be deemed “fast food” even though they appear ‘healthier’ than American fast food.


We call those foods you mentioned as “junky foods” as that’s still a concept in Japan too. It’s usually pretty clear based on nutritional content, but the main reason is how sick you feel afterwards.
There can be healthier options in fast food as well as better ways to prepare karage and tempura to be less unhealthy. And no, none of that appears more or less healthier than American fast food to us, but fast food also includes chipotle and subway which are not quite as greasy as what you have in mind.
