The name comes from the Chinese word for fried chicken, zhájī — the Kushiro shop that coined it inserted an extra "n" sound in the middle, borrowed from the Japanese word for good luck, un.
A whole chicken is hacked into large bone-in pieces, marinated in soy sauce, sake, garlic and ginger, then deep-fried to a dark, heavily seasoned crust and served with a dipping sauce, distinct from plain karaage's simple squeeze of lemon.
