Morinaga Pancake Chocolate Syrup. Best selling chocolate syrup in Japan for decades. When it comes to nostalgic taste in Japan, you won’t find many bigger names than sweets and snacks maker Morinaga. Their popular caramels and chocolates were a childhood favorite of those in the Showa era, so much that they were turned into McShakes for a vintage success. One of the company’s most well-known products, however, is their chocolate syrup, maple syrup and pancake mix, which has even inspired a maple syrup pancake hot spring in Japan.
