Headquartered in Tokyo, Nichirei is one of Japan’s top frozen food producers. It also provides cold storage warehousing and operates globally through 80 subsidiaries. In response to the cyberattack, the company disconnected its systems on July 13, affecting operations at Nichirei Logistics Group’s refrigerated warehouses and Nichirei Foods’ shipping operations. The disruption has affected multiple restaurant chains, retailers, and delivery services, according to local media reports . On Thursday, Nichirei announced (PDF) that it would gradually restore the impacted operations starting Friday, but did not provide details on when services would be fully operational. The frozen food company said its investigation has established that hackers targeted its servers as part of the attack, and that some of the affected systems stored personal information.

The company will continue its investigation and, should any leakage be confirmed, will promptly report the matter to the relevant parties,” it said. Nichirei said it was withholding details of the cyberattack as a precautionary measure, so it is unclear whether it was hit by a known ransomware or data extortion group. The company also noted that it is currently assessing the incident’s impact on its consolidated financial results and that it will disclose any identified material impact.
