Japanese restaurant, want to be a chef, how can an apprentice work in a Japanese restaurant? I am in Shanghai, and I would like to ask you. Think of Japan

If Japanese restaurants are high-end stores, they never recruit inexperienced people to recruit chefs. If it's izakaya or something, you can go in and work without experience. As soon as I came to Japan, I worked in the kitchen in izakaya, and learned how to cut sashimi sushi and fry it, which was a mess. Therefore, I want to study deeply and achieve great success. Either go to which school to lay a good foundation, or go to which shop to accumulate some experience first. I think it's best to find a job and see the real situation of Japanese shops, or go to a Japanese cuisine school. What tools, materials and steps others use are worthy of reference, and then try to enter a high-end restaurant as an apprentice.
