First of all, it must be because Japan's fishery is developed. As the saying goes, relying on mountains to feed on water, Japan is mostly a volcano, so it is impossible to cultivate, so we can only find a way from the sea.

However, there are many areas with developed fisheries all over the world. Why is Japanese sashimi famous all over the world?

Japanese geographical position is superior, and the intersection of ocean cold current and heat current is rich in fish resources. The fish is tender and delicious, and the fish diet is rich in nutrition, which is rich in protein. However, if it is cooked by heating, it will lead to nutrient loss.

In addition, the Japanese can't cook, and the cooking method is relatively simple. Until now, Japanese cooking methods are still relatively simple, far less than China.

Finally, Japan is short of materials and iron resources in history. Iron products are imported from China, and iron tools are luxury goods, resulting in a shortage of cooking tools.
