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.
To be clear, A staple food is something that provides a significant portion of the calories (or other nutrients) in an overall diet.
A single slice of bread for breakfast, which while popular as you point out, simply doesn’t come up to that level. From your own link only 60% of respondents even eat breakfast every day, and 20% don’t eat it at all.
The whole statement I made was that bread just isn’t consumed in the quantities or for the purposes that we have it for in North America, so that’s why trying to find things like Whole Wheat bread is so difficult.

Americans eat on average 37 to 53 pounds of bread per year, or around 50-80 loaves. Around two slices of bread per person per day. Extrapolating from the Japanese situation, their average is probably closer to 1/3rd of that value.
