They may look good enough to eat, but Japan’s mouthwatering food replicas are only for show as restaurateurs compete for the attention of hungry customers. They’re common sights in this food-obsessed nation, with everything from sudsy beers and perfectly glazed sushi to hamburgers and deep-fried pork cutlets, known as tonkatsu, on display. Making food replicas began during the early 1920s, when artists producing models of human organs for doctors were approached by restaurants to do the same thing for the food they wanted to sell.
