The interdependencies among people, communities, and nations are ever present. Much of what we eat has global origins. The fast food you eat in Tokyo may include lettuce from Nagano, onions from China and shrimps from Thailand. Further, relocating production site to overseas is a common corporate strategy for cutting down production costs. For those people who are concerned about food safety, tracing the origins of food is becoming increasingly difficult. Against these backgrounds, we attempt to trace the movement of food by using the analytical framework called the global commodity chains analysis and consider social ramifications deriving from globalization of food.
