　Generally, chickens are not fried whole. Instead, the chicken is divided into its constituent pieces. The white meat sections are the breast and the wings from the front of the chicken, while the dark meat sections are the thighs and legs or "drumsticks" from the rear of the chicken. The breast is typically split into two pieces, and the back is usually discarded. Chicken fingers, which are boneless pieces of chicken breast cut into long strips, are also commonly used.
　American-style fried chicken gradually passed into everyday use as a general Southern dish, especially after the abolition of slavery, and its popularity spread. Since fried chicken traveled well in hot weather before refrigeration was commonplace and industry growth reduced its cost, it gained further favor across the South. Fried chicken continues to be among this region's top choices for "Sunday dinner". Holidays such as Independence Day and other gatherings often feature this dish. During the 20th century, chain restaurants focused on fried chicken began among the boom in the fast food industry. Brands such as Kentucky Fried Chicken (KFC) and Popeyes expanded in the United States and across the world.　(From Wikipedia)

　The original term "chicken karaage" existed in Japan, but this expression became popular due to the expansion of the restaurant industry that originated from the United States.
