Tinkering with the Colonel’s chicken seems to be the norm at KFC Japan. Most recently, they’ve introduced new Ginger Salt Fried Chicken (previously they offered chicken with a rice breading).
The chicken is flecked with black sesame seeds and comes with a ginger seasoning packet to sprinkle on before eating for more ginger flavor.
KFC Japan is not cheap though. A single piece comes in at 260 yen (or about $3.23 US).
In addition to the Ginger Salt Fried Chicken, KFC is also offering a Ginger Chicken Soup for the winter season. For 290 yen (~$3.61 US), it features a dashi bonito (fish stock) and chicken base with pieces of chicken, enoki mushrooms, ginger, and vermicelli noodles.
