Interesting, I was under the impression that the food quality in Japan was quite good. Although I suppose I have no reason to believe Europe would be any worse, or different.
What makes you say that Europe has a better food quality?

Japan has a huge problem with counterfeit fish meat (substituting inferior, sometimes toxin tainted, different species meat).
Japan's non-seaweed vegetables are generally watery and not as nutrient rich as what you can get in Europe (rucola & feldsalat, for example). Their staple "vegetable" tends to be a nasty variety of cabbage, and daikon and pumpkin.
Bread in Japan is blanched wheat flour. In Europe there are dozens of grains to choose from. Even grau brot tastes amazing. Japan's XYZ pan couldn't even compare. Home cooked food in France was a truly magical experience.
Bio (organic) is very popular and very strictly regulated in Europe. In Japan they don't care as much, and in the USA its a joke.
It's relatively easy in Europe to get prepackaged foods (such as canned goods/soups & frozen foods) made strictly from first ingredients (there's nothing in the ingredients list you can't pronounce, or that you wouldn't add yourself if making it from scratch).
More space to grow food and a large open market between EU countries, whereas Japan grows a lot of rice on the very limited space they have and is very restrictive wrt. importing foods from abroad. Which is why you can good food in Japan but sometimes fruits are ridiculously expensive. Also, bread in Japan is terrible (but then again, good Japanese food in Europe is tricky too).
