Heinz sells squid ink pasta sauce in Japan. I am not sure how well the product is doing, but squid ink is a standard spaghetti sauce in Japan, and is available at all Italian restaurants. You also see squid ink flavored snacks fairly often - usually as limited edition products.I checked on the US website and did not find any such product for sale in the US by Heinz, so I suppose this was specially developed for the Japanese market.
The love of all things squid is one of many things that overlaps in Japanese and Italian food.
