Class Status within
Liberal Arts Education Biological Science, especially food science in agricultural area. To understand the need for a range of disciplines through chocolate, not just biology (of which agriculture is one), but also history, geography, economics, industry, natural sciences (physics, biology, chemistry, geology), etc.
Area Courses（Courses in Natural Sciences)　Category：Biology
Expected Outcome By deepening their understanding of how chocolate came into contact with mankind, how it has been processed, and the problems it faces today, students will be able to understand that in order to understand a single event, it is necessary to view it as an integrated science, drawing on history, geography, economics, engineering, natural sciences (physics, biology, chemistry, geology), etc. The course also aims to provide students with a deeper understanding of what the various issues are and what they are currently about.

Class Objectives
/Class Outline The objective of the course is to achieve what is stated in the 'Learning outcomes' section above. In other words, the course aims to answer the following questions about chocolate: how does the cocoa bean, the raw material of chocolate, originate, how does the cocoa bean encounter mankind, how is it processed, and how is it finally produced industrially on a mass scale? Furthermore, the aim is to understand the problems faced by cocoa farmers, who are the producers of the cocoa bean, the raw material of chocolate, through history, geography, economics, industry and natural science (physics, biology, chemistry and geology). The aim of the project is to understand the various problems faced by cocoa farmers (cocoa plantations) through history, geography, economics, industry and natural science (physics, biology, chemistry and geology). In this way, the aim is to understand that chocolate, a food and an industrial product, requires a comprehensive understanding from various perspectives throughout the process of its production.
