According to RocketNews24, one of the current items that sits as a "common fixture in Japanese cafes" is a creamy soup corn potage. The result apparently includes KFC launching a deep-fried corn potage fritter, describing their process in a frighteningly nonchalant manner, "We bread the corn potage and cook it to a crisp."
The deep fried soup will be available for a limited time only at KFC locations across Japan starting September 5th.
