【Aging, safety net and fiscal crisis in Japan】No.118: Food Self-Sufficiency Rate

In this column series, Yukihiro Matsuyama, Research Director at CIGS introduces the latest information about aging, safety net and fiscal crisis in Japan with data of international comparison.

When thinking about the safety net for Japanese people, a food self-sufficiency rate is important. The food self-sufficiency rate is an index showing how domestic agricultural production covers much domestic food consumption. There are two definitions, a food self-sufficiency rate based on the production value and a food self-sufficiency rate based on calories. Figure 1 shows the calculation formula and the historical trend.

According to the Ministry of Agriculture, Forestry and Fisheries, the food self-sufficiency rate based on the production value declined from 86% in 1965 to 68% in 2016. The food self-sufficiency rate based on calories dropped further from 73% to 38% during the same period. The ministry also released international comparative data. As shown in Figure 2, Japan's food self-sufficiency rate is the lowest among developed countries. This suggests that, if there is a sharp depreciation of the yen triggered by financial collapse and so on in the future, this will be a major obstacle to food security.
