Japanese set meal restaurant chains, including industry leader Ootoya, have reportedly been enjoying a surge in popularity. The secret behind this trend seems to be the traditional and home-style appeal of the meals they serve, which are typically well balanced, nutritious, and based on locally sourced ingredients. The trend highlights the shifting dining preferences of Japanese consumers, who are increasingly seeking wholesome and comforting meals.

In Japan, set meal restaurants are valued for their reflection of the country's culinary culture that emphasizes seasonal ingredients and balanced nutrition. These places often become a favorite for individuals, families, and even salarymen due to their affordability and the feeling of home-style cooking.

In comparison, in the US and EU, although fast food and convenience are often prioritized, there is a growing movement towards farm-to-table concepts and health-conscious dining, which echoes the Japanese dining trend of nutritious set meals.
