Your description is unclear.

Japanese sushi, such as sushi, is as cheap as 8,1,12 yen per plate, which is equivalent to RMB 6-8 yuan RMB per plate, far lower than the price of sushi restaurants in China.

to be precise, it should be said that "Japanese sushi" in China is expensive!

The reason is that many marine fish used to make "sashimi" in China are imported.

In addition, the store rent is expensive, and the salaries of Japanese chefs are high.
