It didn't take long for the truth to be revealed: these pigs were plastic replicas for restaurant window displays, used to attract customers.
As a traditional part of Japanese restaurant culture, realistic looking handcrafted replicas originated around 1920.
They are supposed to be an accurate expression of the items on the menu.
Tokyo-based food replica company Nagao Sample released the images using Twitter on July 17 and immediately sparked debate on the web.
While some online users said that the realness of the pigs destroyed their appetite, others praised the creator’s craftsmanship.
These photos have also generated thought-provoking discussions over inhumane animal slaughter and meat consumption.
Nagao Sample welcomed the different opinions and said they wanted to expand the production of these plastic food replicas.
These weird food creations are far from unusual though.
Uncanny products such as pink soya sauce and excrement-shaped chocolate all exist in Japan.
A company in Aomori, a Northern city in Japan, has created different garlic flavoured products, like garlic beer and garlic ice cream.
