Japan’s Food Self-Sufficiency Slips Further from Goal

Japan’s food self-sufficiency ratio has slipped to 37% for the fiscal year ended March 31, down one percentage point from the previous year and still far below the government’s 45% target for fiscal 2030. That figure measures how much of the country’s food supply is produced domestically on a calorie basis — and it tells a story Japan has been wrestling with for decades.

Japan is a wealthy country with advanced technology, but wealth does not grow wheat, soybeans, or feed grain by itself. The nation depends heavily on imports for many staples and livestock feed ingredients. That leaves consumers and producers exposed to exchange rates, shipping disruptions, trade tensions, and global crop failures.

For Japanese farmers, the number reflects familiar challenges: aging farm operators, fragmented land, high production costs, and competition from imports. Yet it also points to opportunity. If policymakers are serious about raising self-sufficiency, support may need to flow toward land consolidation, younger farmers, smart machinery, feed production, and crops that replace vulnerable imports.

Livestock producers will be watching closely because feed is a major piece of the self-sufficiency puzzle. A country can produce meat, milk, and eggs domestically while still relying on imported corn and soy to feed the animals. True resilience means looking upstream, all the way back to the ration.

Japan’s situation is a reminder for every country: food security is not something you buy once and store on a shelf. It has to be planted, staffed, financed, and renewed season after season.
