In 2018, the United States exported nuts worth 465 million dollars (422 million Euros) to Japan. As a result, Japan has become the 8th largest overseas market for American nuts. In particular, almonds and walnuts are exported, which accounts for more than half of the total import of nuts and nut products in Japan during 2018.
The years in the overview above correspond to the Japanese fiscal year that starts on 1 April.
Japan is dependent on imports for most of its nut consumption. Almonds and walnuts are supplied almost exclusively by the United States. Salted mixed nuts remain a popular snack in the retail market, while unsalted nuts are gaining popularity due to the supposed health benefits. The United States is the second largest supplier of peanuts to Japan after China. As a result of the trade agreement between Japan and the US, American peanuts have a tariff advantage over Chinese peanuts, which will certainly have an effect on trade.
