A B-grade Nakajima restaurant is a standard of measurement in the Japanese food industry and a basis for consumers to judge the quality of a restaurant. Nakashima restaurants are usually categorized as Class A, Class B and Class C. Class B Nakashima restaurants are Chinese restaurants that are moderately priced, have a certain level of in-store environment and service, and have better-tasting food. Although their grades are not as good as Grade A Nakashima stores, Grade B Nakashima stores are more cost-effective and favored by consumers.

The history of B-grade Nakashima restaurants can be traced back to the 1950s, when Japan's economy was growing rapidly and the fast-food culture began to take hold in the country. In order to meet the consumer demands of a fast-paced lifestyle, many catering companies began to offer fast food items that were affordable, had quick preparation times, and tasted good. These caterers quickly became the first choice of consumers, and the concept of the B-grade Nakajima restaurant emerged as a measure of the quality of fast food.
