First, Japan is relatively small and the transportation is relatively expensive. Long-term hiking makes Japanese girls have enough exercise without fitness. There are always many thin and beautiful girls on the streets of Japan. Why are there so few local fat women? They can keep such a good figure with little exercise? Thanks to the expensive local transportation. Japan itself is rare, but the most impressive thing is that transportation is super expensive. In order to save money, many girls walk to school directly. Enough exercise every day keeps Japanese girls in good shape, and almost no extra exercise is needed. Of course, some girls will still be influenced by genes and look fatter.
Second, the diversification and small amount of diet make Japanese girls have poor physical maintenance and obesity is not serious. In addition to getting enough exercise every day, Japan's special food culture is also an important factor leading to girls' good figure maintenance; The diet in Japan is indeed diverse. Almost every meal has a lot of dishes, but the amount is super small. It is enough to add 5-6 dishes and rice in one night. The amount of these dishes is almost only one bite! On the contrary, domestic food is mainly in large quantities, which leads to domestic girls being mainly fat, while Japanese girls give people the feeling of being thin and beautiful. If it is a small series, it is estimated that they will be able to slim down after going to Japan for one year.
Adequate exercise and a small amount of food culture have led to Japanese girls' well-maintained bodies and no need for fitness.
