The claim
中国からの食料輸入がなくなったら日本の食卓はイモだらけ?
Original review summary
The review says the viral image depicts a hypothetical diet based on Japan producing all its food domestically, not the effect of imports from China alone: “拡散した画像は、中国を含むすべての国からの食料輸入が止まった場合のシミュレーション” and “『中国から食料輸入が止まった場合』を想定した画像ではない.” It reports that Chinese imports made up 2% of Japan’s food supply by calories in fiscal 2024, and concludes that losing those imports alone would not produce the pictured situation: “カロリーベースでは2％” and “中国から食料の輸入が途絶えただけで、拡散した画像のような食料事情になることはない.”[S1]
Additional context
The review traces the image to a scenario assuming full domestic food self-sufficiency, rather than a disruption limited to China: “日本が食料を輸入せずに100％自給した場合の食卓” and “中国を含むすべての国からの食料輸入が止まった場合.” [S1]
It also notes that fertilizer is a separate food-security concern, reporting that Japan imports much of its chemical fertilizer and much of its ammonium phosphate from China: “日本は化学肥料の大半を輸入に頼っており、特にりん酸アンモニウムの多くを中国から輸入している.” [S1]
