The wooden fish barbecue was mixed with some minced chicken, and a small round poached egg was lying on the white rice. The Japanese call it Shao. After eating, two people are not hungry even if they work until one or two in the afternoon.

Rice balls are a kind of traditional food in ancient China, which was popularized as military food in the Han Dynasty and later spread to Japan. The main ingredient is rice and the main ingredient is fish fillets. Producers can add ingredients according to their own preferences, and they can also make rice balls of various styles according to their own preferences.

Rice balls have changed since the age of 1970. The traditional impression of rice balls is that in a fluffy white rice, the stuffing may be roasted salmon, and the whole rice ball is covered with seaweed by the mother. And convenience stores have completely changed this picture.

Since the convenience store appeared in the 1970 s, rice balls have become one of the most important commodities in convenience stores, and they still maintain this status today. Due to the development of a packaging method to separate rice from seaweed, seaweed can remain crisp and consumers can enjoy rice balls without getting their hands dirty, which makes rice balls sold in convenience stores popular.

The choice of fillings in rice balls is also very diverse, and there are many fillings with foreign flavors, which makes this precious Japanese cuisine more exotic.
