FamilyMart, a Japanese convenience chain has apologised to its customers after a video showing rats wandering around in one of its stores was released by the public.

The chain stated that it closed down the store for now and felt extremely sorry if the “unsanitary” video had made several customers feel “uneasy” about the products purchased from their stores.

The video, which was circulating on social media on Monday, shows around six rats wandering around the store, particularly right next to sushi displays. Some rats appear to be rushing under shelves that are holding packaged items.

According to NHK, Japan’s national broadcasting company, the clip racked up more than five million views.

FamilyMart started investigating the cause of the rat outbreak, and since the release of the video, the company has closed down a store in the Shibuya district, one of its most popular stores.

In a statement translated from Japanese, the company said “[we] apologise deeply for making you feel uncomfortable and uneasy.”

The company also added that it “will proceed with measures such as disinfection,” whilst also removing and carefully disposing of any tainted products found in the store.

Apart from having numerous stores in Japan, FamilyMart also has plenty of outlets all across Asia.
