A convenience store in Tokyo has been forced to shut after rats were filmed scampering down the walls, along shelves and across aisles. Video clips posted on social media appear to show at least six of the rodents, with some descending from refrigerated display racks. The company that owns the convenience store chain, FamilyMart, apologised. 'We deeply apologise for making you feel uncomfortable and uneasy,' it said. The store is in Tokyo's popular Shibuya district and has been closed until further notice
