Japanese beer exports to South Korea hit zero last month amid boycotts sparked by a simmering trade row between the Asian neighbours.
Official figures on Thursday showed Japan food exports were down 58.1% in October, according to broadcaster NHK.
Sake shipments tumbled more than 90% and instant noodles also flat-lined, it said.
What began as a diplomatic feud over wartime labour compensation has evolved into a trade row between the countries.
The dispute has hit various industries, from Japanese car makers to Korean electronics suppliers.
Beer-sellers have been among the hardest hit. Japan shipped 800.34m yen ($7.3m; £5.6m) worth of beer to South Korea last October, according to news agency Kyodo.
South Korea is one of the biggest markets for Japanese beer, accounting for about 60% of total overseas shipments last year, Kyodo said.
