The vegetables and meat here in the US don't taste the same — I don't know if it's the way they make it or grow it. I also feel like things last longer in Japan. For example, if you were to buy cucumbers in Japan, they wouldn't rot for a while, but here, a couple of days later, they get moldy.
My daily meals would typically be rice, a choice of protein, lots of vegetables, and a soup. A lot of Japanese people have okazu, which are small side dishes of different vegetables. Here in the US, it's more like, you have your carbs and protein and salad or something like that, but over there it's a lot more varied.
