**Overview** The labor shortage in the manufacturing industry is becoming increasingly serious year by year, with particularly low employment rates among young people and high turnover rates posing significant challenges. In a situation where it is difficult to increase personnel, "environmental improvement" is crucial for maintaining productivity and achieving sustainable growth for companies. This seminar will focus on the improvement of "things," "people," and "information," explaining how to create a workplace where "people do not leave" through enhancing employee motivation and standardizing operations. Additionally, we will introduce specific approaches to environmental improvement, incorporating examples of successful initiatives using Kamikashi. **Program** 1. What are the causes of labor shortages in the food industry? 2. The importance of improving "things," "people," and "information" on-site. 3. Examples of successful workplace creation through digitalization.
